基于身份的无可信中心Ad-hoc密钥管理方案

Identity-based without a Trusted Center Key Management Scheme in Ad-hoc Networks

针对移动Ad-hoc网络中迫切需要解决的安全问题是建立一个安全、高效、可行的密钥管理系统,提出了一种基于身份无可信中心的适合于Ad-hoc网络密钥管理方案,有效地解决了节点间的信任问题及基于身份密码体制的密钥托管问题,并给出了一种可以为用户在线周期性更新密钥机制。最后证明了所得用户公钥与用户身份的绑定及用户私钥的安全性。

The security issue needed to be solved urgently in mobile Ad-hoc networks is to build a safe,efficient and feasible key management system.This paper presents a suitable Ad-hoc networks key management scheme,which uses identity-based cryptosystem without trusted center.It effectively solves the issue of the trust between nodes and identity-based cryptography key escrow issues.And it gives a user key online periodically update mechanism.finally,It turns out that the obtained public key is binding with the user identity and proved the safety of the user private key.
