摘要： 针对移动节点移动到外地网络时媒体无关切换(MIH)的服务安全问题，提出一种基于diameter的密钥分发方案，为移动节点和外地MIH服务器建立信任关系，使用消息鉴别码为MIH信令提供完整性保护。使用BAN逻辑对密钥分发方案的安全性进行证明，分析表明该方案性能优于同类方案。

Abstract: To solve the Media Independent Handover(MIH) security issue when the mobile node roams into the foreign network, this paper provides a key distribution solution based on diameter protocol to set up trust relationship between the mobile node and the MIH server, and offers the integrity protection to the MIH signaling by using the message authentication code mechanism. It proves the security of IKEv2 pre-shared key distribution by using BAN logic, and analyzes the performance of this solution. According to the analysis result, the performance of this solution is better than other related solution.

Key words: Media Independent Handover(MIH), pre-shared key, BAN logic
