SM3 acceleration method and device

Abstract

The embodiment of the invention relates to an SM3 acceleration method and device. The method comprises the following steps: carrying out message filling and grouping on an input message to obtain a grouped message; performing message expansion on each grouped message to generate an expanded message word group; performing compression function calculation on each extended message word group to obtain a calculation result; wherein at least one of the message extension and the compression function calculation is realized through an extension instruction; and storing the calculation result in a preset register. According to the embodiment of the invention, a software and hardware combination mode is adopted, so that the efficiency of SM3 operation is effectively improved, the cost is considered, and better configuration of resources is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to an SM3 acceleration method and device. Background technique [0002] SM3 is a cryptographic hash algorithm (GM / T 0004-2012) released by the State Cryptography Administration, for the length less than 2 64 For bit information, the SM3 hash algorithm undergoes padding, iterative compression and output selection to generate a 256-bit hash value. For some computing devices, such as general-purpose processors, when using pure software to perform SM3 hash operations, there are often disadvantages of low efficiency and long-term occupation of the device, which leads to tight allocation of system resources and increased power consumption. For some hardware solutions, pure hardware realizes SM3 hash operation, which increases the hardware cost too much. How to improve the efficiency of SM3 computing while taking into account the cost to achieve a better a...
