查询词典 cipher code

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。

This text-editor encrypts your text using the ULTRA cipher and stores it in usn files with the Crypto Message Format.

这个文本编辑器可以使用ULTRA密码来加密你的文本，用Crypto Message Format格式将其保存在usn文件中。

In order to save the space of memory, the local C/A code generator based on RAM, NCO based on CORDIC algorithm and the code phase detector based on Robertson approximate algorithm were proposed in this paper.

设计过程中，为了节约存储空间还提出了基于RAM的本地C/A码产生器、基于CORDIC算法的NCO和基于Robertson近似算法实现的码相位鉴别器等。

From demesne code arrives source code, this one market precedes platform realized software history to go up most about-face.

从私有代码到开源代码，这一市场领先平台实现了软件历史上的最大转变。

The range of application of the abstract provisions in a civil code is much larger than the pigeonhole system of anglo-american case law.it must be borne in mind,however,that behind the screen of the general terms of a civil code the courts develop a bulk of so-called case law that in many ways resembles its counterpart in the common law.although the means by which a certain solution to a legal problem is reached may be strikingly different,the results tend to be very much the same under common-law and civil influence.

适用范围的抽象规定，在一部民法典是远大于扣压制度的英美案例law.it必须紧记，不过，这背后的屏幕上的一般条款，一部民法典法院发展散装的，所以所谓的判例法在许多方面相似，其对应在共同law.although手段，其中某一方案的一个法律问题是达成的，可突出不同，但结果往往是极为相似的共同下-法律和民间的影响力。

Pachomius manual labour was organized as an essential part of the monastic life; and since it is a principle of the monks as distinguished from the mendicants, that the body shall be self-supporting, external work of one sort or another has been an inevitable part of the life ever since.

根据圣pachomius体力劳动组织作为一个重要组成部分寺院生活；以来，这是一个原则的和尚，作为有别于乞丐，该机构应自支撑，对外工作的这种或那种已一个必然的一部分，生活至今。

In order to study the effects of parametrical rolling on the ship movement and tilts, in allusion to ship's navigating in regular following waves, the equation of ship rolling motion is transformed into normal Mathieu equation by proper variable replacement when strong parametrical excitation in restoring moment varied according to sine or cosine wave.

为研究参数横摇对船舶运动和倾覆的影响，通过对船在规则波上随浪航行时，恢复力矩中出现的1个以正余弦规律变化的强参数激励项进行适当的变量置换，将船舶的横摇运动方程转换成标准形式的Mathieu方程。
