数据加密算法研究与应用

Research and Application of Data Encryption Algorithm

公钥加密和对称加密各有其优缺点，为了能够实现这两种加密算法的互补，本文在公钥加密和对称加密算法的基础上研究一种组合加密算法，使得其具备公钥加密的安全性和对称加密的便捷性。

Public key encryption and symmetric encryption has its own advantages and disadvantages,in order to achieve complementarity of the two encryption algorithms,this public-key encryption and symmetric encryption in the algorithm based on the study a combination of encryption algorithm,making it with public key encryption safety and convenience of symmetric encryption.
