detailed description

Example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown.

Fig. 1 shows a flowchart of a method for generating machine codes according to an embodiment of the present invention.

As shown in FIG. 1 , at step 101 , device information of a computer is acquired. The device information includes: a combination of part or all of at least one hardware serial number of the computer. For example, the hardware serial number can be the CPU serial number, hard disk serial number, network card serial number, graphics card serial number, etc. of the device, and the device information can be the CPU serial number, hard disk serial number, network card serial number, graphics card serial number, etc. Part of a serial number or a combination of parts of multiple serial numbers, it can also be all of a serial number or all of multiple serial numbers among the CPU serial number, hard disk serial number, network card serial number, graphics card serial number, etc. The combination. For example, device information can be obtained through the computer's operating system.

In an example, the obtained device information may be a part of the hard disk serial number, the hard disk serial number is "JP2940J82STPVV", and the device information may be "JP2940J8".

In step 102, each character in the device information is encrypted to generate a first character string. Characters can be encrypted using various encryption algorithms.

A method for encrypting each character in device information to generate a first character string according to an embodiment of the present invention will be described below with reference to FIG. 2 .

Fig. 2 shows a flowchart of a method for encrypting each character in device information to generate a first character string according to an embodiment of the present invention.

In step 201, each character in the device information is replaced with a corresponding ASCII code value to generate an ASCII code value group. Here, the replacement is performed based on the American Standard Code Table for Information Interchange (ASCII Code Table). That is, find the numerical value corresponding to the character in the ASCII code table, and replace the character with the corresponding numerical value, so as to generate an ASCII code value group.

In an example, the ASCII code value group obtained by replacing the obtained device information "JP2940J8" with the corresponding ASCII code value is: 74 80 50 57 52 48 74 56.

In step 202, the ASCII code values in the ASCII code value group are divided into N (N is a natural number greater than zero) groups according to predetermined rules, and each group corresponds to a predetermined mathematical operation. The predetermined rules here may be various methods capable of grouping. For example, grouping by a predetermined number, grouping by odd-numbered positions and even-numbered positions may be performed. For example, the predetermined mathematical operation corresponding to each group may be one of addition, subtraction and multiplication. It should be understood that the predetermined mathematical operation is not limited thereto.

It should be understood that when N=1, all the ASCII code values in the ASCII code value group are divided into one group. In other words, the group of ASCII code values is not divided. Meanwhile, when N=1, each ASCII code value in the ASCII code value group performs the same predetermined mathematical operation. The predetermined mathematical operation may be addition, subtraction or multiplication.

In an example, the ASCII code value group "74 80 50 57 52 48 74 56" is divided into 2 groups in units of 4, the first group is: 74 80 50 57, and the second group is: 52 48 74 56 . The predetermined mathematical operation corresponding to the first group is addition, and the predetermined mathematical operation corresponding to the second group is subtraction.

In step 203, a predetermined mathematical operation corresponding to the group in which each ASCII code value belongs is performed on each ASCII code value and the first preset value. That is, each group grouped in step 202 corresponds to a predetermined mathematical operation, and the ASCII code value in each group and the first preset value are subjected to a predetermined mathematical operation corresponding to the group. For example: when N in step 202 is 2, the predetermined mathematical operation corresponding to the first group can be a kind of mathematical operation in addition, subtraction and multiplication, and the predetermined mathematical operation corresponding to the second group can be addition, subtraction and multiplication Another mathematical operation in . When N in step 202 is 3, the predetermined mathematical operation corresponding to the first group may be multiplication, the predetermined mathematical operation corresponding to the second group may be addition, and the predetermined mathematical operation corresponding to the third group may be subtraction. The first preset value may be any integer. It can be understood that when the predetermined mathematical operation is multiplication, the first preset value is any non-zero integer.

In an example, after grouping the ASCII code value groups, the first group is: 74 80 50 57, the second group is: 52 48 74 56, the first preset value is 7, and the first group corresponds to the predetermined mathematical operation is addition, and the predetermined mathematical operation corresponding to the second group is subtraction, then the result obtained after the predetermined mathematical operation corresponding to the first group and the first preset value is: 81 8757 64, the second group is carried out with the first preset value The result obtained after the corresponding predetermined mathematical operation is: 45 41 67 49.

In another example, after grouping the ASCII code value groups, the first group is: 74 80 50 57, the second group is: 52 48 74 56, the first preset value is 50, and the first group corresponds to the predetermined math The operation is addition, and the predetermined mathematical operation corresponding to the second group is subtraction, then the result obtained after the predetermined mathematical operation corresponding to the first group and the first preset value is: 124130 100 107, the second group and the first preset value The result obtained after performing the corresponding predetermined mathematical operation is: 2 -2 24 6.

In step 204, it is determined whether the number of digits of the result obtained after each predetermined mathematical operation reaches the predetermined number of digits. It should be understood that when there is a negative sign in the result obtained by the operation, the number of digits of the result includes the number of digits of the negative sign and the number of digits; when there is no negative sign in the result obtained by the operation, only the number of digits is included. digits.

The predetermined number of digits is the maximum number of digits of the results obtained after performing predetermined mathematical operations corresponding to different groups of all ASCII code values in the ASCII code table and the first preset value. The number of digits of the result here is the same as the above. When the result obtained by the operation has a negative sign, the number of digits of the result includes the number of digits of the negative sign and the number of digits; when the result obtained by the operation does not have a When negative, only include the number of digits. Based on the ASCII code table, it can be seen that the value range of the ASCII code value is [0, 127], and then all the ASCII code values in the ASCII code table are obtained after performing predetermined mathematical operations corresponding to different groups with the first preset value The numerical value having the largest median has a predetermined number of digits.

In one example, the first preset value is 7, the predetermined mathematical operation corresponding to the first group is addition, and the predetermined mathematical operation corresponding to the second group is subtraction, then all ASCII code values in the ASCII code table are respectively added with the first The maximum number of digits of all results obtained after a preset value of 7 and all ASCII codes in the ASCII code table after subtracting the first preset value of 7 is 3 digits. That is, the predetermined number of digits is 3 digits.

In another example, the first preset value is 50, the predetermined mathematical operation corresponding to the first group is addition, and the predetermined mathematical operation corresponding to the second group is subtraction, then all ASCII code values in the ASCII code table are respectively added The maximum number of digits of all the results obtained after the first preset value of 50 and all the ASCII codes in the ASCII code table is 3 digits after subtracting the first preset value of 50. . That is, the predetermined number of digits is 3 digits.

In step 205, zero values are added before the result that does not reach the predetermined number of digits, so that the result reaches the predetermined number of digits. That is, zero values are added before the results obtained in step 203 where the median of the results is less than the predetermined number of digits.

In one example, the result obtained after performing the predetermined mathematical operation in the example shown in step 203 is: 8187 57 64 45 41 67 49, due to the pre-positioning of the example shown in step 203 in the example shown in step 204 The number is determined to be 3, so after adding zero values before the result that does not reach the predetermined number of digits: 081 087 057 064 045 041067 049.

In another example, the result obtained after performing the predetermined mathematical operation in the example shown in step 203 is: 124 130 100 107 2 -2 24 6, because the example shown in step 204 is compared to the example shown in step 203 The predetermined number of digits is determined to be 3, so after adding zero values before the result that does not reach the predetermined number of digits: 124 130 100 107002 0-2 024 006.

In step 206, the results obtained after performing predetermined mathematical operations are arranged according to the sequence of the corresponding ASCII code values in the ASCII code value group obtained in step 201 to generate a first character string. That is, the results obtained in step 205 are still arranged according to the sequence of the corresponding ASCII code values in the ASCII code value group to generate the first character string.

In one example, the result obtained in step 205 is: 081 087 057 064 045 041 067 049, and the first character string "081087057064045041067049" is obtained by arranging according to the order of the corresponding ASCII code values in the ASCII code value group.

In another example, the result obtained in step 205 is: 124 130 100 107 002 0-2 024 006, and the first character string "1241301001070020-2024006" is obtained by arranging according to the order of the corresponding ASCII code values in the ASCII code value group.

Returning to FIG. 1 , at step 103 , the character group corresponding to each character in the first character string is determined. In one example, each character in the first character string corresponds to a character group, each character group includes at least one Chinese character, and there are no identical Chinese characters among different character groups. Specifically, there can be 11 character groups, and the content of each character group is as follows:

Character group (0): mixed with chan 鋋 廛 flatter intestine factory 麨 hate 漦 瘛 摴 kitchen hoe 諔 嘬 sore 摐 噇 踳 give vinegar to destroy;

Character group (1): 鰆, stirrup, upsetting, iron, mace, 镢, 鐍锎, shackle, continuation, phosphonium, 镤, praseodymium, 镪, tattoo, 謦, salamander, 繻worm gill;

Character group (2): 饆can cicada 繟 焭 牟 懤 young 繮 storage 炮 鄜 pick cadmium ring filthy 劐 gallium armor town weaving 镏铎Nie;

Character group (3): step on the charm, pity, amazement, surprise, anger, and sorrow, order, sorrow, thick, toad, Chu, chu, stupid, Cong, weary, rubbing;

Character group (4): 怊伡 疢 宬 fear wears through the spring 殂 promoting poison degree 怏 gadolinium palace 剞 刭 咓 咕 庥 xu xu xu xu xuan ku;

Character group (5): toad, shovel, pomfret, punishment, delay, favor, speech, Cu, prayer, dysprosium, dial, calf, mirror, keng, delicacy, selection, gilt, carved, trowel, anchor, 镆, move;

Character group (6): 艑艑色色话嘥僝嘉玚綝调感质兲琊搊琊琊琊琊琊琊琊琊磯箠波搋僢悠感喜女色;

Character group (7): Shencao's side hairpin produces prostitutes, often wanders and sings nests in the morning, 琤瓻 spoon, soy sauce, Chong 紬 灢 place, sips the boat;

Character group (8): adz meal 憯 穇 cabin rough 蹅 peer 鹨 阊 氅 鋹 Chen 踸 赪 褫 long 瘳 kick 遄 frontier hammer 輴 猞ci;

Character group (9): rubbing operation 艚 螬 懆 馇 馇 锸 Zen compensation 韔 鼌 帱 憷 歜 deposes 膗 Cong alone plated forging E pot 锾 emblem;

Character group (-): file toot osmium front apply zirconium 馓 骟 release widow 铴 璺 gnaw nickel twist scorpion que que tin block cobalt potassium before suppressing victory.

The characters in () of each character group are characters corresponding to the character group.

In step 104, each character in the first character string is replaced with any character in the corresponding character group to form a machine code. That is, for each character in the first character string, a character is randomly selected from the character group corresponding to the character, and the character is replaced.

In one example, the machine code obtained after replacing each character in the first string "081087057064045041067049" is: .

In another example, the machine code obtained after replacing each character in the first character string "1241301001070020-2024006" is: Mo said angrily.

According to the method for generating machine code according to the embodiment of the present invention shown in FIG. 1 and the method for encrypting each character in the device information according to the embodiment of the present invention shown in FIG. 2 to generate the first character string, it is possible The machine code used to generate the registration code is generated based on the equipment information of the computer, and the machine code is composed of a group of Chinese characters, so as to effectively protect the software development results.

Fig. 3 shows a flowchart of a method for generating a registration code according to an embodiment of the present invention.

As shown in FIG. 3, in step 301, a machine code is received. Here, the received machine code may be the machine code sent by the electronic terminal, or the machine code input manually.

In one example, the received machine code is: 问船销股諔酲酲食柔柔耏铹耏皮皮鸡踳鉞韔.

In another example, the received machine code is: 镢繟宬镄感瘛破脱呴吧童continue嘬摐摐战小斗艟艟缦Can wear麨旨言.

In step 302, the character group corresponding to each character in the machine code is determined. That is, determine in which character group each character in the machine code exists. Here, each character group includes at least one Chinese character, and there are no identical Chinese characters among different character groups.

In one example, the machine code is: 闹船锋肻諔酲食重重重摐耏铹炎皮鸡鸳鉞韔. A character in the machine code is "chan", based on the content of the aforementioned character group, it can be known that the character "chan" exists in the character group (0), that is, the character group corresponding to the character "chan" is the character group ( 0).

In step 303, each character in the machine code is replaced with the character corresponding to the corresponding character group to obtain the first character string. That is, based on the correspondence between the aforementioned character groups and characters, each character in the machine code is replaced with the character corresponding to the corresponding character group.

In one example, a character "chan" in the machine code can be replaced with the character "0" corresponding to the corresponding character group (0), and so on, the machine code "chan" After replacing each character in "Poisonous Hoe, Fear, Drum, Scalp, Scalp, Silk, Scalp, Scalp", the first character string can be obtained: 081087057064045041067049.

In another example, after replacing each character in the machine code "镢繟宬镄喜瘛破破" and "头繟箬镄盛瘛破" to get the first character string: 1241301001070020-2024006.

In step 304, the first character string is decrypted to obtain decrypted information. The first character string may be decrypted by using a decryption algorithm corresponding to the encryption algorithm.

A method for decrypting a first character string to obtain decrypted information according to an embodiment of the present invention will be described below with reference to FIG. 4 . Here, the first character string is encrypted using the method shown in FIG. 2 . It can be understood that the decrypted information obtained here is device information.

Fig. 4 shows a flowchart of a method for decrypting a first character string to obtain decrypted information according to an embodiment of the present invention.

In step 401, the characters in the first character string are divided into multiple parts in units of predetermined digits. Here, the predetermined number of digits is the maximum number of digits of the results obtained after performing predetermined mathematical operations corresponding to different groups of all ASCII code values in the ASCII code table and the first preset value. The number of digits of the result here is the same as the above. When the result obtained by the operation has a negative sign, the number of digits of the result includes the number of digits of the negative sign and the number of digits; when the result obtained by the operation does not contain When negative, only include the number of digits. The first preset value is the same as the first preset value in the corresponding encryption process. The predetermined mathematical operations corresponding to different groups are predetermined mathematical operations corresponding to different groups in the corresponding encryption process. The method for determining the predetermined number of digits is the same as the corresponding The method of determining the predetermined number of digits in the encryption process is the same. That is, the predetermined number of digits here is the same as that in the corresponding encryption process.

In an example, the first character string is: 081087057064045041067049, the first default value is 7, the corresponding predetermined mathematical operations corresponding to different groups in the encryption process are addition and subtraction, and the predetermined number of digits is 3. The multiple parts obtained by dividing the first character string in units of 3 predetermined digits are: 081 087 057 064 045 041 067 049.

In another example, the first character string is: 1241301001070020-2024006, the first preset value is 7, the corresponding predetermined mathematical operations corresponding to different groups in the encryption process are addition and subtraction, and the predetermined number of digits is 3. The multiple parts obtained by dividing the first character string in units of 3 predetermined digits are: 124 130 100 107 002 0-2 024 006.

In step 402, the zero value to the left of the first non-zero character from the left of each part is removed.

In one example, the zero value on the left side of the first non-zero character from the left of the multiple parts "081 087 057 064045 041 067 049" obtained in the example shown in step 401 is removed to obtain: 81 87 57 64 4541 67 49.

In another example, the zero value on the left side of the first non-zero character from the left of the multiple parts "124 130 100 107002 0-2 024 006" obtained in the example shown in step 401 is removed Get: 124 130 100107 2 -2 24 6.

In step 403, the multiple parts obtained in step 401 are divided into N (N is a natural number greater than zero) groups according to predetermined rules, and each group corresponds to a predetermined mathematical operation. The predetermined rules here can be the same various methods that can be grouped as the predetermined rules in the corresponding encryption process, for example, in the corresponding encryption process, grouping is performed by a predetermined number, and the predetermined rule here is to group by a predetermined number , corresponding to grouping by odd-numbered positions and even-numbered positions in the encryption process, and the predetermined rule here is to group by odd-numbered positions and even-numbered positions. The predetermined mathematical operation corresponding to each group is the inverse operation of the predetermined mathematical operation corresponding to the corresponding group in the corresponding encryption process. For example, in the corresponding encryption process, the predetermined mathematical operation corresponding to the first group is addition, the predetermined mathematical operation corresponding to the second group is subtraction, and the predetermined mathematical operation corresponding to the third group is multiplication, then the predetermined mathematical operation corresponding to the first group here is The mathematical operation is subtraction, the predetermined mathematical operation corresponding to the second group is addition, and the predetermined mathematical operation corresponding to the third group is division.

In one example, the multiple parts "81 87 57 64 45 41 6749" obtained in the example shown in step 402 are grouped according to the same method as the predetermined rule in the corresponding encryption process. That is, 4 units are divided into 2 groups, the first group is: 81 87 57 64, and the second group is: 45 41 67 49. Since in the encryption process corresponding to the first character string "081087057064045041067049" in the example shown in step 401, the predetermined mathematical budget corresponding to the first group is addition, and the predetermined mathematical operation corresponding to the second group is subtraction, so here The predetermined mathematical operation corresponding to the first group is subtraction, and the predetermined mathematical operation corresponding to the second group is addition.

In another example, the multiple parts "124 130 100 107 2-2 24 6" obtained in the example shown in step 402 are grouped according to the same method as the predetermined rule in the corresponding encryption process. That is, 4 units are divided into 2 groups, the first group is: 124 130 100 107, and the second group is: 2 -2 24 6. Since in the encryption process corresponding to the first character string "1241301001070020-2024006" in the example shown in step 401, the predetermined mathematical budget corresponding to the first group is addition, and the predetermined mathematical operation corresponding to the second group is subtraction, Therefore, the predetermined mathematical operation corresponding to the first group here is subtraction, and the predetermined mathematical operation corresponding to the second group is addition.

In step 404, a predetermined mathematical operation corresponding to the group of each part is performed on each part and the first preset value. That is, each group grouped in step 403 corresponds to a predetermined mathematical operation, and each part in each group performs a predetermined mathematical operation corresponding to the group with the first preset value.

In one example, the first preset value is 7, the predetermined mathematical operation corresponding to the first group "81 87 57 64" is subtraction, and the predetermined mathematical operation corresponding to the second group "45 41 67 49" is addition, then the first The result obtained after the predetermined mathematical operation corresponding to the first preset value is: 74 80 50 57, and the result obtained after the predetermined mathematical operation corresponding to the second group is 52 48 74 56.

In another example, the first preset value is 50, the predetermined mathematical operation corresponding to the first group "124 130 100 107" is subtraction, and the predetermined mathematical operation corresponding to the second group "2 -2 24 6" is addition, then The result obtained after the first group of predetermined mathematical operations corresponding to the first preset value is: 74 80 50 57, and the result obtained after the second group of predetermined mathematical operations corresponding to the first preset value is: 52 48 74 56.

In step 405, each numerical value obtained by the predetermined mathematical operation is replaced with a corresponding ASCII code character, so as to obtain decryption information. Here, the replacement is performed based on the American Standard Code Table for Information Interchange (ASCII Code Table). That is, find the character corresponding to the numerical value in the ASCII code table, and replace the numerical value with the corresponding character, so as to obtain the decrypted information.

In one example, the result "74 80 50 57 52 48 74 56" obtained by the predetermined mathematical operation is replaced with ASCII code characters to obtain the decrypted information: JP2940J8.

Returning to Fig. 3, in step 305, each character in the decrypted information obtained by decrypting in step 304 is encrypted to generate a second character string. The second character string is different from the first character string. Characters can be encrypted using various encryption algorithms.

In an example, the encryption method here may be the same as the method of encrypting each character in the device information to generate the first character string according to the embodiment of the present invention shown in FIG. Two preset values are used to perform predetermined mathematical operations corresponding to the group in which each ASCII code value belongs to each ASCII code value, while the method shown in FIG. 2 uses the first preset value. The second preset value is any integer different from the first preset value, so that the second character string generated by encryption is different from the first character string. It can be understood that when the predetermined mathematical operation is multiplication, the second preset value is Any non-zero integer different from the first preset value.

In step 306, a character group corresponding to each character in the second character string is determined. In an example, each character in the second character string corresponds to a character group, each character group includes at least one Chinese character, and there are no identical Chinese characters among different character groups. Specifically, there may be 11 character groups, and the content of each character group is as described above. The characters in () of each character group are characters corresponding to the character group.

In step 307, each character in the second character string is replaced with any character in the corresponding character group to form a registration code. That is, for each character in the second character string, a character is randomly extracted from the character group corresponding to the character, and the character is replaced.

In one example, the second character string is: 0354036003300337-228-232-206-224, and the registration code obtained after replacing each character in the second character string is: The factory toad is stupid, the key is to release the scorpion, the tin, the cong, the storage, the armor, the sore, the blunderbuss, and the weaving.

According to the method for generating a registration code according to the embodiment of the present invention shown in FIG. 3 and the method for decrypting the first character string to obtain the decrypted information according to the embodiment of the present invention shown in FIG. 4 , it can be based on the obtained machine code Generate a registration code, which is composed of a group of Chinese characters, so as to effectively protect the software development results.

That is, it is determined in which character group each character in the registration code exists. Here, each character group includes at least one Chinese character, and there are no identical Chinese characters among different character groups.

In one example, the registration code is: 噇絺芝舡冲悲成士都火絺竔堂都着键码繟儭赪銐抐顺益骨防病针打结爭. For the character "噇" in the registration code, based on the content of the aforementioned character group, it can be known that the character "噇" exists in the character group (0). That is, the character group corresponding to the character "噇" is the character group (0).

In step 503, each character in the registration code is replaced with a character corresponding to the corresponding character group to obtain a second character string. That is, based on the correspondence between the aforementioned character groups and characters, each character in the registration code is replaced with a character corresponding to the corresponding character group.

In one example, each character in the registration code "噇絺芝舡冲悲父爷爷爷火火狔堂肠病魔节繟儭赪犐抐皮盟窟防病舡冲早父爭" can be replaced after each character in the registration code The obtained second character string is: 0354036003300337-228-232-206-224.

In step 504, the second character string is decrypted to obtain decrypted information.

In step 508, after it is determined that the software has passed the registration, a registration file is created under the preset path, the registration code is written into the registration file, the creation time of the registration file is modified to past time, and the file attribute is set to hidden. Here, the preset path can be set to any path, for example, the preset path can be set to C:\windows\system32\ or C:\winnt\system32\. The created registration file is used to store the registration code, and the file name and extension can be set arbitrarily, for example, the file name and extension of the registration file can be set as C0MCAT.dll. The past time may be any time before the current time, for example, it may be 2004-8-17 20:00:00.

In step 506, if it is judged that the decrypted information is inconsistent with the device information obtained in step 505, then step 509 is executed to prompt that the registration code is wrong.

That is, based on the correspondence between the aforementioned character groups and characters, each character in the registration code is replaced with a character corresponding to the corresponding character group.

In step 605, the second character string is decrypted to obtain decrypted information. The second character string may be decrypted using a decryption algorithm corresponding to the encryption algorithm.

For example, when the second character string is obtained by using the encryption method shown in FIG. 2 with the second preset value, the decryption method here is the same as that shown in FIG. The information method is the same, the difference is that in step 605, the second preset value is used to decrypt the second character string, while in the method of FIG. 4 , the first character string is decrypted using the first preset value.

In step 606, the device information of the computer is obtained. Here, the acquired device information is the device information of the computer on which the software is currently installed. For example, device information can be obtained through the computer's operating system.

In step 607, it is determined whether the decrypted information obtained in step 605 is consistent with the device information obtained in step 606, and if the decrypted information is consistent with the device information obtained in step 606, then step 608 is executed to open all functions of the software.
