摘要：

在基于身份的Ad Hoc网络密钥管理的方案中，根据用户身份生成用户密钥时无法对用户的身份真实性进行有效确认，针对这一问题，该文结合基于身份的密码系统和基于口令的认证技术，给出一个密钥管理方案，该方案通过口令技术实现节点身份的认证，使用基于身份的密钥管理系统完成密钥的安全分发。同时基于ROM 模型证明了该方案的安全性。

Abstract: Identity-Based Cryptographic(IBC) schemes are considered to secure Ad Hoc networks due to their efficient key management properties. However, proposed schemes do not provide efficient mechanisms for identity authentication. In order to solve this problem a new key management scheme is promoted combining with identity-based and password authentication in this paper. The peer identity is identified by password in Ad Hoc networks. It shows that identity-based key management schemes are effective and efficient for key distributing. The formal proof of its security is presented based on the ROM model.
