| 摘 要： | 本文针对建立在对等方式下的融合网络提出了一种新的认证和密钥更新算法.认证包括三个方面:非漫游状态下的完整认证、漫游状态下的完整认证以及切换状态下的快速认证.密钥更新包括两个方面:非漫游状态下的密钥更新和漫游状态下的密钥更新.在算法中,通过引入认证中心,不仅实现了网络对用户身份的认证,而且实现了节点对网络身份的认证,由此保证了双方身份的合法性;同时为了实现切换的无缝性,采用节点对认证数据包进行中继转发的方式,减少了切换时的认证时间.性能分析表明,该算法能够有效地抵御常见攻击.

| Abstract: | This paper proposes an authentication and key-update algorithm for heterogeneous wireless networks which are based on the peer to peer network architecture.The authentication includes three aspects:the full authentication in the state of non-roaming,the full authentication in the state of roaming,and the local fast authentication in the state of handoff.The key-update includes two aspects:the update in the state of non-roaming and the update in the state of roaming.A certifi- cation authority is introduced,... |
