摘要
根据哈希函数链的单向性,设计出一种基于哈希函数链的密钥分发机制,通过将哈希链与对称加密算法和非对称加密算法的结合应用,为每个用户组的成员分发特定的服务密钥,实现了密钥分发的实时性、动态性和安全性。
Based on hash chains, a real time key distribution of group communication is designed.In this scheme with the hash chain the special application key to the user in the group is provided,and sending the keys online and ensure its safety.
