摘要 以同步序列密码为模型,在分析目前提出的选择Ⅳ统计分析典型框架的基础上,提出了一个新的更一般的选择Ⅳ统计分析框架,并且在该框架下给出了两个重要的统计测试分析方法,分别可以用来作为密钥流区分器和随机性检测器。此外,作为本文提出的框架和分析方法的一个应用,对eSTREAM入选算法Trivium进行了选择Ⅳ统计分析。 This paper proposes a new framework for chosen-Ⅳ statistical analysis of synchronous stream ciphers based on the presently typical framework.Two significant statistical tests are also presented under the new framework,which can be used as a keystream distinguisher and a randomness tester respectively.Moreover,the framework and tests are applied to Trivium which has been selected into the eSTREAM portfolios of promising stream ciphers for hardware.
