Abstract: Ad Hoc network, composed by a collection of mobile nodes, is a temporary autonomic system. Since Ad Hoc Network doesn’t rely on any fixed network facilities, there exist a lot of security problems. Although ID-based authenticated key can achieve authentication and realize secret communication, the general communication is a difficult problem because there are no trusted third parties in Ad Hoc network. This paper proposes an ID-based key exchange protocol that can be applied in Ad Hoc network. The design of which is based on the idea of the polynomial secret share and the ID-based authenticated key exchange under PKI.

Key words: Polynomial secret share, Bilinear pairings, Forward security

摘要： Ad Hoc网络是一种由移动节点组成的临时性自治系统，不依赖于任何固定的网络设施，因此存在着安全隐患，而基于身份的认证密钥交换虽然可以在Ad Hoc网络中实现认证并解决秘密通信问题，但由于在无线Ad Hoc中没有可信第三方结点，密钥成为比较难解决的问题。该文利用多项式秘密共享的思想，提出了一种应用于无线Ad Hoc网络中的基于身份的认证密钥交换协议，此协议是在公钥基础体制下基于身份的密钥交换协议的基础上实现的。
