邮件加密算法PGP的改进

Improvement of Mail Encryption Algorithm PGP

从PGP算法的核心算法IDEA,RSA,MD5入手,分析了每一个算法的安全性,并针对RSA,MD5提出了2种改进的算法:基于RSA的概率加密算法以及基于Rijndael的哈希函数,对这2种算法各项性能进行理论分析和测试,得出它们具有很高的安全性和可靠性.

Trom the aspect of he central algorithms consisting of the PGP algorithm: IDEA,RSA,MD5,the security of each algorithm is analyzed,algorithms are put forward: a PEC algorithm based on RSA and a new hash function based on Rijndael. Through the theoretic analysis and test of the performance of the two algorithms, a conclusion is drawn that they have very high security and reliability.
