查询词典 cipher machine

Security analyses of a variant of a new block cipher system based on cellular automata theory are given using two cryptanalytic approaches. The results show that this variant of CAC is very insecure under chosen-plaintext attacks.

利用两种方法对一个基于细胞自动机的分组密码系统CAC的变形进行了分析，结果表明：CAC的这种变形在选择明文攻击下是极不安全的。

Secondly, the pseudo-chaotic stream cipher based on searching plaintext in a pseudo-random symbolic sequence is analyzed, by several successful cryptanalytic attacks such as one-time pad attacks, bifurcation diagram attacks, entropy attacks, differential attacks and key recovery attacks etc..

第二章研究了基于搜索机制的数字混沌序列密码算法，并详细分析了包括一次一密攻击，分叉图攻击，熵攻击，差分攻击以及基于符号动力学的攻击方法。

I see about two new cipher designs from amateur cryptographers every week.

每周，我都能看到大约两个来自爱好者的新的密码设计。

And since anyone can create a cipher that he believes to be secure, this means that cryptographers should only look at ciphers created by people whose opinions are worth something.

由于每个人都可以创造一个密码算法并相信它是安全，这意味着密码学家只会看那些其观点具有某种价值的人们创造的密码算法。

Some cryptographers worry about the security of AES . They feel that the margin between the number of rounds specified in the cipher and the best known attacks is too small for comfort.

由於已遭破解的弱版的AES，其加密回圈数和原本的加密回圈数相差无几，有些密码学家开始担心 AES 的安全性：要是有人能将该著名的攻击加以改进，这个区块加密系统就会被破解。

In f-act, the algorithm of S-box construction enjoys extremely highly nonlinear and h-igh level of confusion and diffusion. In contrast to most or all commonly known symmetric encryption algorithm designs (including the AES candidates such as Rijndael and Twofish), the Polymorphic Cipher proposed by C.B.

S盒是分组密码中重要的非线性组成部分，需要混淆和扩散性能好，高度非线性的算法来构造，和大多数通常已知的对称性加密算法(包括AES的代表算法例如Rijndael和Twofish)相比较，C.B。
