Property.
Below, with reference to Fig. 1, the encryption method for data that the application is provided is described in detail：
First, step S101 is performed, the logical operation function for encryption is write based on preset function template, it is described to be used for
The logical operation function of encryption includes at least two and calculates function, and the preset function template includes at least one template type.
Specifically, logical operation function has a variety of, for example addition function, SUbtractive function, multiplication function etc., this implementation
Logical operation function in example at least includes two kinds, and the preset function template includes at least one template type, specific
In implementation process, logical operation function can be write using the preset function template of various template type is included.
In order to illustrate more clearly of the logical operation function write based on preset function template for encryption, below with one
It is discussed in detail exemplified by specific preset function template, the general type of preset function template first is as follows：
template<Class data type parameters identifier 1 ..., class data type parameters identifiers n>
<Return type><Function name>(parameter list)
{
Function body
}
Wherein, template is non-data type parameters in the keyword of preset function template statement, angle brackets below
Identifier, can have one or more, different data type parameters identifiers to represent different template types, wherein class
For the keyword of template type.Then non-function in the return type of function, function name and parameter list, braces is followed successively by below
Body.Preset function template is a general template, and data type parameters identifier is actually a type parameter, is made
During with preset function template, the data type that the above-mentioned type parameter is instantiated as determining.After type parameter is instantiated
Parameter is referred to as template argument, and the function instantiated with template argument is referred to as stencil function.I.e. by by preset function template instances
Change, then can obtain the corresponding stencil function of preset function template.Lower mask body introduces what several utilization stencil functions were write
The method of logical operation function.
The first, add operation function is write using stencil function.
Wherein, template<Class T, class T1, class T2, class T3, class T4, class T5>It is
The statement of one stencil function, that is, notify the template type of the compiler stencil function to have 6, the number of template type can root
It is configured according to being actually needed.In above-mentioned function, inline is represented directly deploy during call function, and data type is used
The type that template T is represented, and data type is modified using const, pData and the formal parameter that add is the function,
The type represented using T, and modified with const, the effect of the function is that this function is to add one to parameter pData
Add numerical value, if data are encrypted using the addition function, pData is initial data, and using the base in pData
Initial data is encrypted plus an add numerical value on plinth.
Second, subtraction function is write using stencil function.
The effect of the function is that an add numerical value is subtracted to parameter pData, and SubData is function name, other and addition
Operation function is identical, will not be repeated here.
The third, XOR function is write using stencil function.
The effect of the function is that XorData is function name to one add numerical value of parameter pData XORs, other and addition
Operation function is identical, will not be repeated here.
4th kind, shift left operation function is write using stencil function.
The effect of the function is that an add numerical value is moved to left to parameter pData, and LeftData is function name, other with adding
Method operation function is identical, will not be repeated here.
5th kind, shift left operation function is write using stencil function.
The effect of the function is that an add numerical value is moved to right to parameter pData, and RightData is function name, other with adding
Method operation function is identical, will not be repeated here.
Similarly, other logical operation functions can also be designed, such as multiplying, division arithmetic.
Then step S102 is performed：The different calculating functions in the logical operation function are combined, first function is obtained；
In specific implementation process, the first letter can be obtained by the logical operation function in combination step S101
Number, the mode of combination can have a variety of, such as combination additional calculation function and XOR calculating function, combination subtraction function,
Subtraction function, function etc. is moved to left, and for a variety of logical operation functions of combination, can be by adjusting each logic
Operation function calls order to obtain different first functions, for example, combination additional calculation function and XOR calculate function
First function, it is one kind that addition, which is first carried out, and performs subtraction again, and it is then another first letter that subtraction, which is first carried out, and performs addition again
Number.The logical operation function different by combining obtains first function, can improve the complexity of first function.
The implementation method of first function is introduced with a specific example below, it is assumed that need to be sent to client service
The user behavior data of device is encrypted.Its initial data is：PData=" first page test
Hit1234566.... ", the initial data is long character string, it is however generally that client when being communicated with server,
Server can issue a KEY value and be used for that initial data is encrypted, and this KEY value is also a long character string, it is assumed that KEY:
PKey=" abcdef1234567899........... ", then the implementation method of first function is as follows：The logical operation letter of combination
Several orders is addition function, SUbtractive function, XOR function, moves to left function etc., may then pass through a circulation to realize
The function of first function：
For int i=0；i<pDataLen；i++；
{
AddData<int,char,int,int,int,int>(pData[i],pKey[i])；
SubData<int,char,int,int,int,int>(pData[i],pKey[i])；
XorData<int,char,int,int,int,int>(pData[i],pKey[i])；
LeftData<int,char,int,int,int,int>(pData[i],pKey[i])；
}
Wherein, pDataLen refers to the length of data, and i is loop parameter, and initial value is that 0, pData [0] is initial data
The first digit, i.e., " f ", pKey [0] be " a ", then be first carried out " f+a ", can be by being converted into specific implementation process
ASCII (American Standard Code for Information Interchange, ASCII American Standard Code for Information Interchange generation
Code) calculated.Above-mentioned code this operation be pData data are added with pKey data, subtracted each other, XOR, a left side
Operation is moved to be encrypted.
On the basis of the above, using generic function come calling logic operation function, so as to generate first function.
Wherein, EncodeData1 is the function name of first function, and remaining parameter declaration has hereinbefore made correlation
Explain with illustrating, will not be repeated here, very huge function generation can be generated for the final compiler of EncodeData1 functions
Code, and the stencil function wherein called can all generate a different logical operation function.
With above-mentioned EncodeData1 functions accordingly, it can be deduced that the inverse process of decryption function, i.e. AES.Example
If AES carries out addition to data, then decipherment algorithm is then to carry out subtraction, and it is decipherment algorithm that order, which is turned around,.
For example it is then for function EncodeData1 decipherment algorithm：
Next step S103 is performed：The template type is changed, and based on amended template type and described first
Function generates encryption function.
Optionally, the template type includes at least one data type；The modification template type, and be based on repairing
Template type and first function generation encryption function after changing, including：
By changing the data type, so as to change the template type, and amended template type is obtained；
According to the amended template type, the encrypted code of the code of multiple first functions is generated, will be described
Encrypted code is used as the encryption function.
Specifically, it is foregoing to have obtained the different first functions for calculating function of combination, it is using default due to calculating function
Function template is write, and preset function template includes at least one template type, then can be by changing template type
Mode obtain multiple encrypted codes, contain the code of first function in the encrypted code.
In specific implementation process, template parameter T1, T2, T3, T4, T5 in step S101 can be carried out different
Instantiation, to realize the modification to template type, for amended template type, compiler can all regenerate a addition
Code, so as to write a function, any a variety of encrypted codes can be then generated by changing template type.Implement
It is as follows：
Assuming that template type T is int types, the data to be encrypted are 1, and addend is 2, then calls the knot of add operation function
It is really as follows：
Int a=1；
Int b=2；
Int c=AddData<int,int,int,int,int,int>(a,b)；
Now, compiler can generate a type for int, int, int, int, int, int addition code.
If T1 type is revised as into char types, call the result of add operation function as follows：
Int c=AddData<int,char,int,int,int,int>(a,b)；
Likewise, compiler can generate a type for int, char, int, int, int, int addition code.
The result return for calling above two function is 3, but arbitrarily changes a kind of template type, and compiler can all give birth to
Into a addition code, for example：
Int c=AddData<int,char,int,int,int,int>(a,b)；
Int c=AddData<int,char,char,int,int,int>(a,b)；
Int c=AddData<int,char,float,int,int,int>(a,b)；
And in C Plus Plus, specific template type has int, char, float, double, int*, customization type etc.
Deng, therefore template type is infinite, and by changing any one template type, then different a codes can be obtained,
Size of code is so considerably increased, difficulty is cracked so as to improve.
Step S104 is performed again：Based on the encryption function, the data are encrypted.
Specifically, encryption function is generated based on amended template type and the first function in step S103,
Data can be then encrypted by encryption function, because modification template type can then obtain different encryption functions
Code, and template type be it is infinite multiple, each template can be changed, therefore the code of obtained encryption function is very huge
Big, if to be cracked to encryption function, the code of all encryption functions of decompiling is needed, has so added and has cracked number
According to the difficulty of encryption function, so improve the security of data encryption.
Alternatively, in order to further improve the complexity of encryption function, changing the template type, and based on modification after
Template type and first function generation encryption function, methods described also includes：
Based on the preset function template, the encryption function is converted into the mould corresponding with the preset function template
First encryption function of plate type function.
Specifically, because logical operation function is write based on preset function template, adjusted by generic function
Use logical operation function, you can to realize the function of stencil function, can be by order to further improve the complexity of encryption function
Encryption function is converted into corresponding stencil function, and the stencil function is the further complication on the basis of encryption function, i.e.,
First encryption function.In specific implementation process, in the first encryption function of stencil function type, the template type of use with
Logical operation function is consistent, and is implemented as follows：
template<class T,class T1,class T2,class T3,class T4,class T5>
void EncodeData(T const&pData,T const&add)
{
AddData<T,T1,T2,T3,T4,T5>(pData[i],pKey[i])；
SubData<T,T1,T2,T3,T4,T5>(pData[i],pKey[i])；
XorData<T,T1,T2,T3,T4,T5>(pData[i],pKey[i])；
}
Now, can be to template type if template parameter T1, T2, T3, T4, T5 of modification EncodeData functions
Modify, compiler can all generate portion EncodeData code for each type, so as to improve size of code, also increase
Add the complexity of code, difficulty is cracked so adding, improve the security of data encryption.
