摘　　要：针对互联网通信过程存在信息泄露的风险,提出了一种基于混合加密算法的安全通信系统,主要功能包括建立安全通信连接和发送即时数据.首先采用RSA算法对服务端和客户端进行双向身份认证,再通过AES算法和SHA算法将发送数据加密生成密文和数字签名,最后再将密文和数字签名一起发送给对方进行验证.与其他混合加密算法相比,提出的混合加密算法计算复杂度更小、耗时更短,在保证安全性的前提下极大地提高了通信的传输效率.Aiming at the risk of information leakage in the process of Internet communication,a secure communication system based on hybrid encryption algorithm is proposed.The main functions include establishing secure communication connection and sending instant data,firstly,the RSA algorithm is used to perform two-way identity authentication between the server and the client,then,AES algorithm and SHA algorithm are used to send data encryption to generate ciphertext and digital signature,and finally,the ciphertext and digital signature are sent to each other for verification.The experimental results show that compared to the other hybird encryption alogrithms,the proposed hybird encrytion algorithm has less computational complexity and time consuming,which greatly improves the transmission efficiency of communication under the premise of ensuring security.
