摘要
基于分簇结构提出一种Ad Hoc网络安全撤销方案。采用基于身份的密码算法,不需要公钥证书的存在,使用Beta信誉模型为网络中节点预测簇内其他节点的行为提供理论完善的基础。结合门限机制实现节点的撤销,避免簇头撤销权力的集中,可解决节点簇间漫游的安全隐患,增强网络的安全性。
This paper presents a secure revocation scheme for cluster-based Ad Hoc networks. This scheme uses ID-based signcryption and public key certificates are not needed. It offers a theoretically sound basis for a node in Mobile Ad Hoc Networks（MANETs） to predict the behavior of other nodes in the same cluster by using Beta reputation system. Combining with threshold mechanism to realize the revocation of nodes, it provides protection against the power of revocation being controlled. It defects in the roaming of mobile nodes and enhances security.
