融合多重加解密算法的保密通信系统

Secure communication system with combination of multiple encryption algorithm

针对移动电子商务中的信息安全需求,提出一种融合AES、RSA和CPRS混沌3种加解密方式的保密通信系统。分析系统实现原理,设计三层密钥模型和3种加密算法在系统中的优化实现过程,发挥3种加密算法各自的优势,对程序执行代码、用户身份和语音等信息进行多重加密。实验结果表明,该方法可以克服传统单一方法在密钥管理上的缺陷,增加了加密的安全性,可有效用于移动电子商务等保密传输系统,具有良好的数据保密通信效果。

For information security needs in mobile E-commerce, a secure communication system was proposed, which integrated three kinds of encryption and decryption methods including AES, RSA and CPRS. The system implementation principles, three key models and three encryption algorithms were described respectively in optimized implementation of the system, three encryp- tion algorithms of their respective advantages were fully taken advantage of by the system, multiple encryption was conducted on program execution code, the user identity and voice information etc. Experimental results show that the method can overcome the de- fects of traditional single method of the key management, greatly increasing the security of the encryptiora The method can be effectively used for mobile electronic commerce security transmission system. It has good effect on data encrvDtion communication.
