基于通用可重构处理器的AES算法设计与实现
Design and Implementation of AES Algorithm Based on General Reconfigurable Processor
摘要
Abstract
Based on the architecture of General Reconfigurable Processor(GReP),this paper proposes an Advanced Encryption Standard(AES)-128 implementation scheme,which is optimized in algorithm structure,Processing Element (PE) utilization ratio and storage cost.This scheme uses a 256 bit x 32 bit look-up table to complete the byte instead of mixing with the column on encryption time,improves PE utilization ratio through data decomposition and data stream decomposition,and reduces storage overhead through local register and reasonable layout of PE.Experimental result indicates that,PE utilization ratio reaches 60％ and memory access cost reduces 74％ than totally using shared memory.Compared with the serial method on Intel Atom230,this scheme increases throughput rate by about 100％.关键词
