IKEv2在基于IP的无线自组网中的应用研究

Research on Application of IKEv2 in Ad-Hoc IP Networks

无线自组网络没有专门的密钥管理协议,其安全性一直备受关注。IKEv2是目前IP网络中使用最广泛的密钥管理协议,但它不是专门为无线网络环境设计的。文章根据IKEv2使用的认证方法的不同提出了两个改进协议。这两个协议都使用无线自组网络认证方法—MANA证书来认证响应者,从而减少密码算法计算量,让IKEv2为无线自组网提供密钥管理服务。

Ad hoe networks has no its own special key management protocol and its security is always paid close attention by many researchers. IKEv2 is a key management protocol which is widely exploited in IP networks, but it is not designed for radio networks. This paper presents two improved protoeols according to different authentication methods in IKEv2. They both authentic-ate the responder by MANA certificate which is an authentication approach of Ad hoe networks, then it can minimize computations of cryptography algorithms to adapt IKEv2 for the special authentication requirements of ad-hoc networks.
