Embodiment 1
[0037] The main idea of the present invention is that the device adopts 16 basic message word registers and 3 dynamic message word registers, based on the characteristics of the SM3 algorithm itself: in the calculation of 64 rounds, in the calculation of the 0th round to the 11th round, The 16 basic message word registers are not reassigned. Starting from the 12th round of calculation, the 16 basic message word registers are dynamically assigned. The present invention can realize the SM3 algorithm by using 19 registers, which greatly reduces the hardware based on the SM3 algorithm. area.
[0038] The hardware implementation device of SM3 algorithm, such as figure 1 As shown, it includes an interface module (AHB interface) for receiving the original message data (Message) and outputting the encrypted result (Result), which allows the SM3 module to be mounted on the AHB bus, and the SM3 module can be accessed through the AHB bus;
[0039] Also includes: FIFO storage module fo...
