【摘要】：反馈移位寄存器是众多流密码算法的核心部件,加快反馈移位寄存器操作是提高流密码处理速度的关键.为提高传统流密码算法中反馈移位寄存器软件实现性能,在分析通用微处理器上反馈移位操作特征的基础上,设计了相应的反馈移位寄存器RISC扩展指令和灵活高效的硬件支持单元,构建了基于NIOSⅡ的SOPC测试平台,测试结果表明,使用扩展指令后,通用微处理器上反馈移位操作性能最大提高7.5倍,而流密码算法软件实现性能也随之提高了3~4倍.
[Abstract]:Feedback shift register is the core part of many stream cipher algorithms. The key to improve the speed of stream cipher processing is to speed up the operation of feedback shift register, in order to improve the performance of feedback shift register software in traditional stream cipher algorithm. On the basis of analyzing the characteristics of feedback shift operation on general microprocessor, the corresponding feedback shift register RISC extended instruction and flexible and efficient hardware support unit are designed, and the SOPC test platform based on NIOS 鈪，
