一种改进的组播密钥管理方案
Improved Multicast Key Management Scheme
摘要
Abstract
Aiming at the problems that multicast key management scheme exists forward confidentiality, backward confidentiality and conspiracy cracked, this paper presents an improved multicast key management scheme. It includes multicast authentication, secure multicast forwarding tree management, key distribution when users are initialized and periodical key updating. It reduces the complexity of the key updating problem when members leave the group by two-layer control and guarantee the efficiency and security of key management. Experimental result shows that this scheme performs better on computation cost and communication cost, and it has acceptable storage cost.关键词
