Embodiment 1
[0043] This embodiment provides an accelerated processing method based on high-level synthesis of the national secret algorithm SM4;
[0044] Such as figure 1 As shown, based on the high-level comprehensive national secret algorithm SM4 accelerated processing method, the data packets sent to the server to be processed by the national secret algorithm are processed, including:
[0045] S101: Using the high-level integrated HLS to realize the national secret algorithm SM4 through the high-level programming language; perform simulation processing on the high-level programming language;
[0046] S102: After the simulation process passes normally, perform synthesis to obtain a comprehensive report, and observe the performance of the national secret algorithm through the comprehensive report; use high-level comprehensive HLS to optimize the national secret algorithm SM4, and finally export the IP core through joint simulation, so that High-level comprehensive HLS automatically real...
example 1
[0084] Example 1-realization based on the disclosed SM4 algorithm:
[0085] The implementation of the present disclosure will be described below in conjunction with the accompanying drawings. The design, implementation and acceleration method of the SM4 algorithm based on high-level synthesis described in this implementation, the specific process is as follows:
[0086] First of all, E1 implements the SM4 algorithm through C language. This algorithm has multiple functions to implement, but in this example, in order to describe the problem simply, the algorithm is used as a function, and the input is all fixed length, such as unsigned long*sk, unsigned char*input, unsigned char*output, although the parameters of the function are in the form of pointers, in fact, unsigned long*sk is a 1024bit extended key in the form of unsigned long sk[32] in an encryption process, the same unsigned char *input, unsigned char*output is 128bit input and output information in the form of unsigned...
