摘　　要： 在基于身份公钥系统的基础上,给出新的注册协议。用各实体产生的随机数来计算会话密钥,避免了在无线链路上传输会话密钥,安全的实现了MN,FA及HA三者间的密钥分配。用公钥算法对实体进行认证,并且同时对实体所收发的随机数进行比较,实现了对实体的二次认证。对协议的安全性分析表明其能满足安全通信的条件。 Based on ID-based cryptography system,a new registration protocol is proposed.With the random numbers produced by entities,the session keys can be calculated,avoiding transmitting the session keys on the wireless link and realizing the distribution of the session keys among MN,FA and HA safely.Public key algorithm is employed to authenticate the entities,and at the same time by comparing the random numbers that are received and dispatched by the entities,the entities can be authenticated again.The analysis of the protocol indicates that it can satisfy the conditions of the secure correspondence.
