A Dynamic Layering Scheme of Multicast Key Management

摘要：

Group key management is a difficult task in implementing large and dynamic secure multicast. In this paper, a new scheme is proposed in the basis of indepth analysis of the requirements of the secure multicast and group key management. The scheme is based on the multicast group security architecture and multicast security group key management architecture proposed by IETF. This scheme constructs group key based on pairings and distributes the group key using HSAH function polynomial, and manages group key making use of the dynamic layering GCKS. The scheme is better in security, lower in computation cost and communication cost. The analysis comparison proves that the scheme has strong scalability and efficiency.
