AES

针对32位MIPS微处理器中CLZ指令（对单个字高位连零进行计数）的实现电路，使用了类似于超前进位的逻辑结构。包含测试文档，以及Design Compile所用的环境和脚本。(The CLZ instruction counts the number of leading zeros in a word. The 32-bit word in the GPR rs is scanned from most-significant to least-significant bit.The number of leading zeros is counted and the result is written to the GPR rd. If all 32 bits are cleared in the GPR rs, the result written to the GPR rd is 32. )

这是一个自治的三维混沌系统的彩色图像加密程序，该混沌系统具有优良的动力学特性，加密效果明显有效，且抗干扰能力强，是很好的加密系统。(This is an autonomous chaotic system color image encryption procedures, the chaotic system has excellent dynamic characteristics, the effect is obvious encryption effective, and anti-interference ability, is a good encryption system.)

应用背景一个安全的版本称为安全AODV路由协议AODV（网）。它提供的功能，如完整性，认证，和路由数据的不可否认性。它采用了双方案为确保AODV。维护合作机制的AODV路由协议，包括一种情况允许中间节点回复的委派功能RREQ消息。这就是所谓的双重签名：当一个节点产生一个RREQ消息，除了 ；正规的签名，它可以包括第二签名，这是在一个虚拟的RREP消息向本身的计算。中间节点可以在他们的路由表，以及与其他相关的路由信息节点如果其中一个节点，然后接收RREQ走向节点，它可以在一个代表回复RREP消息，同样，与普通AODV会发生什么。这样做，中间节点生成RREP消息，包括节点的签名，它以前缓存，和符号带有它自己的私有密钥的消息。关键技术网不需要尊重其他消息AODV。然而，网消息明显更大，主要是因为数字签名。而且，情况需要重量级的非对称加密操作：每次一个节点产生一个路由信息，它必须生成签名，每次收到一个签名路由消息（也作为中间节点），它必须验证签名。这会变得更糟的时候，双签名机制是使用，因为这可能需要单个签名的生成或验证信息。在情况允许的操作，网验证AODV路由数据。机制是用于实现此：哈希链和签名

程序采用当前最先进的Rijndael算法作为核心算法，带有可变块长和可变密钥长度的迭代块密码。块长和密钥长度可以分别指定成 128、192 或 256 位。多线程操作，保证加密时程序界面流畅，加密速度大约9M每秒。(Procedures using the most advanced as a core algorithm Rijndael algorithm with variable block length and variable key length of the iterative block password. Block length and key length can be specified as 128,192 or 256. Multi-threaded operation, to ensure smooth program interface encryption, encryption speed of about 9M per second.)
