摘　　要：利用分层的密钥共享体制,提出了一种基于身份的分层的分布式ad hoc组密钥管理方案,避免了将系统密钥平等分发给每个节点,攻破任意K个节点即可更新组密钥的缺陷。并以网格作为逻辑结构,具有了高联通性、低负载、扩展性强的特点。经分析表明,该方案比传统方案更高效、更安全、抗攻击能力更强。An identity-base group key management scheme in ad-hoc was proposed, which was based on distributing key management.In this scheme, nodes were divided into two parts, server nodes and ordinary nodes.The shares held by server nodes included more information than ordinary nodes.The scheme reducing the risk of distributing key shares to all nodes that compromising of any K node would leak the system's group key.The logical structure of the scheme was a grid.This scheme not only has the advantages of high connectivity and low overhand, but also has high expandability.It is analyzed that this scheme is more efficient, security and stronger anti-attack than traditional scheme.
