网络会议密钥发布策略

A Scheme Study of Broadcast Conference Key in Network

主要讨论如何实现基于广播的网上会议密钥的发布.实现机制是建立在TA基础之上的交互密钥分发方案(IKDS).根据策略可以发布使广播会议密钥到一组且将其发送到参加会议会话的具有一定优先权的用户.每一个用户都可以使用他的密钥解密网络会议信息.为了保证网络通信的安全,应采用一种简单而有效的方法来鉴别信息的发送者和接收者.

This paper gives a new scheme based on broadcast keys in the network. The protocol structure uses TA （Trusted Authority） as a key distribution center, and users get the keys from TA. Every user is able to decrypt the information in the network through his known keys. Considering the security of the communication we use a simple and efficient method to authenticate the senders and receivers.
