摘　　要：在分析现有的Ad Hoc网络分布式信任方案基础上,使用双线性对技术提出一个基于身份的Ad Hoc网络密钥管理方案。该方案结合基于身份的密码学算法与分布式秘密共享算法将系统主密钥分发给一组预选节点,由其合作实现私钥生成中心PKG功能。一次单播即可安全高效地实现节点私钥更新,基于双线性对性质,一次交互即可安全地建立节点间的会话密钥。分析结果表明该方案安全高效。Following the analysis of existing distributed trust model to Ad Hoc networks, this paper presents an ID-based key management scheme using bilinear pairing. It employs the secret-sharing technique to distribute system key among a pre-selected set of nodes, called D-PKGs, which offers a collaborative private-key-generator service. The construction method not only ensures secure and efficient network-wide key update, but also establishes session key via only a single message using property of bilinear pairing. Analysis show the scheme is secure and effective.
