摘要
单独使用LFSRs(Linear Feedback Shift Registers)或FCSRs(Feedback with Carry Shift Registers)的序列密码产生系统会存在弱密钥。本文提出了一种Gollmann级联下的LFSRs和FCSRs混合的序列密码系统。该方案通过使用较小参数的多LFSR和FCSR混合来达到长周期、高线性复杂度和良好的统计特性的目的。
The generation of stream ciphers that is based on LFSRs(Linear Feedback Shift Registers) and FCSRs(Feedback with Carry Shift Registers) existed weak keys when using LFSR alone,or FCSR along.We present a stream ciphers combining LFSRs and FCSRs with Gollmann cascade.The method can use the LFSR and FCSR Mixers with less parameter in order to achieve the purpose of long period,high linear complexity and good statistic quality.
