密码分析 meaning in English
cryptanalysis
cryptoanalysis
Examples
- In traditional block cipher , the s - box is the only one nonlinear core component and it determines the strength of these cryptosystems . therefore , the construction of cryptographically strong s - boxes is of much
在传统分组密码学中, s盒是唯一一个非线性运算部件,它的性能直接影响到整个密码系统的强度,它的设计一直是密码设计与密码分析的研究重点。 - Because there is lots of encrypt algorithm in the world , this paper elaborates the core idea , the theory of several algorithm that are more popular at present , and analyzes the resist - cipher - attacking ability of the main algorithm adopted in this applying system
由于目前国际上的加解密算法多种多样，而且比较复杂，因此，本文对其中流行的几种加密算法的核心思想、原理以及选择原则进行了对比，对本课题采用的主要加密算法的抗密码分析攻击能力也进行了剖析。 - 4 . security of a class of block ciphers based on chaotic maps against differential and linear cryptanalysis is studied . the results show that this kind of cipher structure is not good compared with some famous cipher structure such as cast - 256 cipher structure and common feistel structure
对一类基于混沌函数的分组密码结构gfs4 ( gfs8 )的安全性做了评估，分析结果表明：从抵抗差分密码分析和线性密码分析的安全性与所需要的执行代价相比，这类密码结构不如cast - 256型密码结构和普通的feistel型密码结构。 - Adopting this model and properly selecting some nonlinear and linear modules which has good cryptographic properties , a concrete block cipher can thus be constructed , which is provably secure against differential and linear cryptanalysis , and also has self - inverse structure for encryption and decryption
采用该模型，只需适当选取密码特性好的非线性模块和线性模块，就可以构造出具有很好地抵抗差分密码分析和线性密码分析的能力、加解密相似的分组密码算法； 3 - The main sections of this paper are as followed : in the first chapter , some basic concepts and terms of cryptology are introduced , including the classification of cryptology , the sttucture of a typical cryptosystem , the methods of cryptograph analysis and classfy the cryptograph algorithins using different methods
