Abstract

A fast implementation method of the GPU-based SM3 cryptographic hash algorithm, by asynchronously copying messages to be processed from the memory to the video memory of the GPU as a global memory, when the GPU uses the SM3 fast implementation method that contains padding expansion and compression function loop expansion When calculating the hash value, the CPU transmits the next batch of messages at the same time; the GPU outputs the calculation results to the video memory and the CPU reads the results in the video memory and transmits the message digest value. The invention has simple implementation and stable performance, and the SM3 quickly realizes a performance of 1.14 billion Hash / s, which greatly improves the calculation efficiency of the SM3.

Description

technical field [0001] The present invention relates to a technology in the field of information security, in particular to a fast implementation method of the SM3 cryptographic hash algorithm based on OpenCL and GPU. Background technique [0002] Digest algorithms are widely used in important fields such as digital signature, message authentication, data integrity and password protection. Among them, the SM3 algorithm belongs to computing tasks with fewer computing branches, arithmetic-intensive, and high-bandwidth requirements. Using the OpenCL language, the SM3 fast computing service can be realized by taking advantage of the performance advantages of GPU general computing. There are many existing technologies for implementing the SM3 hash algorithm through hardware, but they cannot implement an efficient computing solution for SM3. Contents of the invention [0003] The present invention aims at the prior art, when the CPU transmits messages, the GPU needs to wait for...
