摘　　要：提出了一种超球形的分布式安全多播密钥管理方案。该方案充分利用了分布式多播中成员之间既独立又协同的特点,解决了安全多播密钥的更新问题,更新效率较高,有效地降低了组密钥更新的通信开销,且不增加计算开销和存储开销,并能很好地保证更新时的前向安全性和后向安全性。A distributed multicast rekeying schema based on super geometry sphere was proposed. The schema took full advantage of both independent and collaborative features among members of distributed multicast to solve the security problem of multicast rekeying; in the same time, the higher efficiency updating of the program effectively reduced communication overhead of the group rekeying without increasing the computational and storage overhead and it could ensure the forward and backward security while updating.
