Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1, a wireless communication encryption method according to an embodiment of the present invention includes:
the invention provides a wireless communication encryption method, which comprises the following steps:
s11, step one: acquiring original data;
s12, step two: generating an encryption code based on the original data;
s13, step three: checking the encryption code based on a preset password table, and judging whether the encryption code is used or not, wherein the password table is used for storing the used encryption code;
s14, step four: if yes, executing the step two; if not, encrypting the original data based on a preset encryption rule to obtain encrypted data.
In the above step S11, the original data may include a start bit, a data field, a check field, and an end bit. Wherein the start bit indicates the start of a frame data packet (i.e., a data frame); the end bit indicates the end of a frame data packet; the data field comprises data which needs to be transmitted actually; the Check field includes a Check value for ensuring correctness of data transmission, and in practical application, a CRC (cyclic redundancy Check) mode, a parity mode, and the like may be adopted, which is not specifically limited in the embodiment of the present invention. Wherein, the content of the data field can be customized according to the service requirement. In a specific application, the data frame format may further include a packet length (indicating a total length of a data packet of a frame), a data type (e.g., service data, management data), and the like, which may be defined according to actual requirements.
In the above step S12, when the terminal receives the original data, the encryption code may be randomly generated by the terminal through some algorithm based on the C language. For example, c + +11 < random > c + +11 introduces a < random > header file for generating random numbers. It comprises two parts: random engine, used to generate random bit stream; distribution is used to generate random numbers that meet user requirements. The generated random number may be used as an encryption code. The application method comprises the following steps: random _ device is initialized by using seed, preferably std:, random _ device generates different random bit streams each time the random _ device runs, and if the same sequence is generated at each start-up, a constant int is used for initializing a distribution object by using a min-max range value. The randomly generated encryption code may be obtained in various ways, and is not limited in any way.
In the step S13, after generating the encryption code, it is required to query whether the encryption code of the corresponding original data has been used by table lookup, otherwise, the encryption code is considered to be illegal. Since the encryption code is randomly generated, a repetition with a previously used password is generated with a certain probability. If the cipher table is not set, when the randomly generated encryption code is repeated with the previously used cipher, and when the receiving end decrypts the encrypted data, the used cipher is stored in the cipher table of the receiving end, and the receiving end misunderstands that the encrypted data is cloned, so that the information cannot be decrypted normally. Therefore, when the original data is encrypted at the sending end, the encryption code is checked by using the cipher table, so that the receiving end can be prevented from misjudging the encrypted information, and the normal transmission of the encrypted data is ensured.
At the above step S14, if it is judged that the currently generated encryption code corresponds to the password stored in the password table, it is verified that the encryption code has been used previously. Therefore, a new encryption code needs to be generated again, and then the new encryption code is compared with the password table until the encryption code is verified to be unused, and the original data is encrypted based on a preset encryption rule to obtain encrypted data.
Further, the checking the encryption code based on a preset encryption table to determine whether the encryption code is used, wherein after the step of storing the used encryption code, the checking comprises:
detecting whether the storage space of the password table is completely occupied;
if so, clearing the encryption code added at the first position, and adding the encryption code which is used currently.
Since the storage space of the cipher table is limited, if the storage space of the cipher table is completely occupied, the subsequent storage of the encryption code is affected. Therefore, by removing the encryption code added at the first position, the problems that the performance of the terminal equipment is influenced when the storage space is too much and the storage capacity is full, the program operation error is caused, the new encryption code cannot be stored and the like can be avoided by adding the currently used encryption code.
Further, the cryptographic table is created on a memory of the CPU.
The common wireless communication encryption is generally realized by a complex AES encryption mode, a DES encryption mode, an RC4 encryption mode, a Rabbit encryption mode and a tripleles encryption mode, and the requirements on software and hardware resources are high. The general internet of things equipment has limited CPU computing capability, such as a single chip microcomputer and the like, complex encryption algorithm is not easy to realize, cloning is easy to realize by using a common simple encryption method, illegal equipment access and data monitoring and tampering are difficult to prevent, and the safety of data acquisition cannot be guaranteed. The method and the device are suitable for point-to-point communication in the Internet of things technology, and are used in occasions with small information amount and high encryption requirements, the encryption technology is upgraded by using small cost (CPU (Central processing Unit) operation resources and time), the hardware cost is low, the encryption strength is improved, and information cloning in wireless communication is effectively prevented.
Further, the preset encryption rule comprises: and inserting the encryption code at a preset position of the original data.
Specifically, the encryption code is inserted into the first bit of the original data, the encryption code is inserted into the last bit of the original data, the encryption code is inserted into every predetermined position (for example, 1 bit, 2 bits or 3 bits or more) in the original data, and the like, so as to perform operations such as addition, subtraction, multiplication, division, modulo addition, modulo subtraction, modulo multiplication, and modulo exponentiation. The preset encryption rule can adopt some simple encryption methods to realize the upgrade of the encryption technology with low cost (CPU operation resource and time).
Referring to fig. 2, a wireless communication decryption method includes:
s21, acquiring encrypted data;
s22, acquiring an encryption code according to the encrypted data;
s23, checking the encryption codes based on a preset encryption code table, and judging whether the encryption codes are used or not, wherein the encryption code table is used for storing the used encryption codes;
s24, if yes, the verification is not passed; if not, the encrypted data is decrypted based on a preset decryption rule to obtain decrypted data, and then the decrypted data is further obtained.
The encrypted data in step S21 has the following two cases: the wireless communication encryption method is used for encrypting and sending the original data; or accessed by illegal equipment and data is monitored and tampered. Therefore, the encrypted data described above needs to be identified by the following steps.
In the step S22, the encryption code is identified and extracted according to the rule agreed between the transmitting end and the receiving end. In this step, either the normal encrypted data or the illegally cloned encrypted data needs to obtain the encryption code, so as to facilitate the next identification of the encrypted data.
In the above steps S23 and S24, before each communication confirmation, whether the encryption code of the encrypted data has been used is checked by means of table lookup, and if not, it is determined that the encrypted data is legal; and if used, is deemed illegal. And in the communication verification process, if the password is found to be used, the data is regarded as cloned data, discarded and the verification is not passed. In short, the encryption code is only allowed to be used once, so as to prevent the clone from being reused.
Further, the checking the encryption code based on a preset password table to determine whether the encryption code is used, wherein after the step of storing the used encryption code, the method comprises:
detecting whether the storage space of the password table is completely occupied;
if so, clearing the encryption code added at the first position, and adding the encryption code which is used at present.
Since the storage space of the cipher table is limited, if the storage space of the cipher table is completely occupied, the subsequent storage of the encryption code is affected. Therefore, by removing the first added encryption code, the problems that the performance of the terminal equipment is affected when the storage space is too much and the storage capacity is full, the program operation is wrong, the new encryption code cannot be stored and the like can be avoided by adding the currently used encryption code.
Further, the cryptographic table is created on a memory of the CPU.
The common wireless communication decryption is realized by a complex AES decryption mode, a DES decryption mode, an RC4 decryption mode, a Rabbit decryption mode and a TripleEes decryption mode, and the requirements on software and hardware resources are high. The general internet of things equipment has limited CPU computing capability, such as a single chip microcomputer and the like, complex decryption algorithms are not easy to realize, cloning is easy to be performed by using a common simple decryption method, illegal equipment access and data monitoring and tampering are difficult to prevent, and the safety of data acquisition cannot be guaranteed.

Further, the preset decryption rule includes: and removing the encryption code at a preset position of the encrypted data.
The decryption rules correspond to the encryption rules. And removing the encryption code at the preset position of the encrypted data to obtain the original data, and completing decryption. The decryption process performs operations such as addition, subtraction, multiplication, division, modulo addition, modulo subtraction, modulo multiplication, and modulo exponentiation. The preset decryption rule can adopt some simple encryption methods to realize the upgrade of the encryption technology with low cost (CPU operation resource and time).
