移动IPv4的快速重认证协议

针对移动节点在外地网络移动时的重认证问题，提出一种基于共享密钥的快速重认证协议。在移动节点移动到新的外地代理前，为双方分发重认证密钥，移动节点与新外地代理使用重认证密钥完成认证过程。采用BAN逻辑对协议的安全性进行证明，并比较协议的性能，结果表明，该协议比同类协议更高效。

Protocol of Fast Re-authentication for Mobile IPv4

According to the re-authentication issue when the mobile node roams in the foreign network, this paper gives a fast re-authentication solution based on shared secret. Before the mobile node moves to the new foreign agent, a re-authentication key is distributed to the new foreign agent and the mobile node, and the two entities finish the authentication procedure using the shared key. It proves the security of authorization solution using BAN logic, and compares the performance of this solution with other related solution. Results show that the protocol is much more efficient than other current protocols.
