| 摘 要： | 针对目前MD5基本算法加密结果容易被破解的问题，在研究分析MD5、SHA-1及其系列算法加密原理的基础上，提出一种增加消息摘要长度的优化算法，使得破解时碰撞的概率减少很多倍，增强了系统加密的安全性。安全分析结果表明，MD5优化算法在保留了原算法加密速度的前提下，具有较原算法更好的抗攻击能力

| Abstract: | According to the issue of the basic algorithm MD5 encryption easy to break the outcome ,the paper proposes a Optimization Algorithm based on the research and analysis in the MD5, SHA-1 encryption algorithm and its series of principles algorithm .The new algorithm increases the length of message digest, add reduce the probability of collision many times, and enhance the security of encryption systems. The results of the safety analysis shows that MD5 algorithm to optimize the original algorithm while retaini... |
