网络即时通讯在为人们日常交流带来便利的同时,也伴随着信息泄露、个人隐私被窃等烦扰。如何保证敏感信息在网络上安全的传输成为一个重要的研究课题。基于网络通信的软件都需要采用加密手段来最大限度上对用户的敏感信息进行保护,其中密钥的管理将影响整个系统的性能和安全性。模拟SSL协议原理,提出使用公钥密码进行私密钥的分配,并通过密钥分配中心(KDC)对公钥密码进行认证的解决方案。
Instant messaging for the network to bring convenience to people’s daily communication, but also accompanied by information disclosure, theft of personal privacy and other annoyances. How to ensure the safe transmission of sensitive information on the network has become an important research topic. The software based on network communication needs to adopt the encryption means to protect the sensitive information of users to the maximum extent, in which the key management will affect the performance and security of the whole system. Simulation SSL protocol principle, the use of public key password for private key distribution, and through the key distribution center (KDC) public key password authentication solution.
