在对多种流密码算法生成结构进行分析的基础上,提出一种基于流密码的可重构处理结构,并在总结重构流密码算法使用频率较高的基本操作类型的基础上,为该流密码可重构处理结构设计了一种专用指令集。描述了指令的具体格式,并对指令性能进行了评估。结果表明,该指令集作用在该流密码可重构结构上可灵活高效地实现多种流密码算法。

Based on the analysis of generation structure of many stream cipher algorithms,a reconfigurable processing structure based on stream ciphers is proposed in this paper.Based on summarizing the basic operation types which are used most frequently in reconfiguring the stream ciphers,a special instruction set for that reconfigurable processing structure of stream ciphers is designed.The concrete formats of the instructions are depicted and the performance of the instruction set is evaluated.The result indicates that when acting on the reconfigurable structure of stream ciphers,the instruction set can realize many different stream cipher algorithms flexibly and quickly.
