摘　　要：分析了即时通讯工具的安全性,针对安全性薄弱的特点设计了一套利用椭圆曲线密码系统和AES加密算法相混合的加密方案,该方案保证了即时通讯系统中客户与服务器、用户与用户三方通信过程的安全性.利用Java语言环境在Socket技术支持下开发出实验软件,验证了方案的可行性.The article analyses the safety of the present instant messenger in detail, and designs an encryption scheme based on a mix of elliptic curve cryptography and AES encryption algorithm according to the weakness of the security features of instant messenger. This scheme guarantees the safety of tripartite communication process from client to server and from customer to customer in the instant messaging system. Using the Java language environment in the socket technology, this design develops an experimental software to prove the feasibility.
