CRC32-Dym

说明：  一种64位的DES加密代码，可以使用挂在APB上(dec enc key to 64 bit rate)

各种反分析软件的手法,包括(反Dede,反单步跟踪,反SoftICE,Ollydbg,反静态分析,以及程序自身的CRC32效验等,对于初学者有很大的帮助.-Analysis of various anti-software approach, including the (Anti-Dede, anti-single-step tracking, anti-SoftICE, Ollydbg, anti-static analysis, as well as procedures for their own well-tested, such as CRC32, for beginners and has a great help.

通过调用openssl库进行aes加密，本程序已编译好了openssl，无需在进行编译！生成时请引用lib文件(By calling the openssl library aes encryption, the program has compiled the openssl, without making compilation! Please cite lib files generated)

The use of FPGAs for cryptographic applications is highly attractive for a variety of reasons but at the same time there are many open issues related to the general security of FPGAs. This contribution attempts to provide a state-of-the-art description of this topic. First, the advantages of reconfigurable hardware for cryptographic applications are discussed from a systems perspective. Second, potential security problems of FPGAs are described in detail, followed by a proposal of a some countermeasure. Third, a list of open research problems is provided. Even though there have been many contributions dealing with the algorithmic aspects of cryptographic schemes implemented on FPGAs, this contribution appears to be the first comprehensive treatment of system and security aspects.

MD5是一种被广泛使用的“消息-摘要算法”。实际上就是一个单项散列函数。(MD5 is a widely used " message- digest algorithm." Is actually a single hash function.)

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
