摘要：
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.
