摘要

通过对分组密码算法加密特征的分析，将分组密码算法的并行性划分为分组内同操作并行性、分组内异操作并行性、分组间同操作并行性和分组间异操作并行性等四维度并行性，并根据此提出了基于Amdahl定律的分组密码四维度并行处理模型FDPM.该模型能够指导分组密码处理架构设计，为架构资源配置和并行性开发提供整体建议.以FDPM为依据，提出了一种面向分组密码的可重构流处理架构RCSA，该架构能够有效开发分组密码处理的并行性，在提高密码处理性能的同时也能提高资源利用率.通过算法映射结果分析，证明了FDPM模型的正确性与RCSA架构的高效性.

Abstract

According to the characteristics of block cipher algorithm

the parallelism of block cipher algorithm can be divided into Four Dimensions Parallelism(FDP)

which consists of same operational parallelism in a block

different operational parallelism in a block

same operational parallelism among multiple blocks and different operational parallelism among multiple blocks.Four Dimensions Parallel Processing Model (FDPM) for block cipher based on Amdahl's law was proposed

which can guide the design of block cipher processing architecture and provide the overall suggestions for resource allocation and parallelism development.And then Reconfigurable block Cipher Stream Architecture (RCSA) based on FDPM was proposed

which can effectively develop parallelism of block cipher and improve processing performance and the utilization rate of resources.The experimental results prove the veracity of FDPM and efficiency of RCSA.
