High-speed realization of parallel algorithm for hash computation on multicore cryptographic processor

摘要

Hashing algorithms are used widely in information security area. Having studied the characteristics of traditional cryptographic hashing function and considered the features of multi-core cryptographic processor, this paper proposes a parallel algorithm for hash computation well-suited to multicore cryptographic processor. The algorithm breaks the chain dependencies of the standard hash function by implementing recursive hash to get faster hash implementation. We discuss the theoretical foundation for our mapping framework including security measure and performance measure. The experiments are performed on a PC with a PCIE card including multi-core cryptographic processor as the cipher processing engine. The results show a performance gain by an approximate factor of 7.8 when running on the 8-core cryptographic processor.
