【摘要】：反饋移位寄存器是眾多流密碼算法的核心部件,加快反饋移位寄存器操作是提高流密碼處理速度的關(guān)鍵.為提高傳統(tǒng)流密碼算法中反饋移位寄存器軟件實(shí)現(xiàn)性能,在分析通用微處理器上反饋移位操作特征的基礎(chǔ)上,設(shè)計(jì)了相應(yīng)的反饋移位寄存器RISC擴(kuò)展指令和靈活高效的硬件支持單元,構(gòu)建了基于NIOSⅡ的SOPC測(cè)試平臺(tái),測(cè)試結(jié)果表明,使用擴(kuò)展指令后,通用微處理器上反饋移位操作性能最大提高7.5倍,而流密碼算法軟件實(shí)現(xiàn)性能也隨之提高了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，
