摘　　要：在组播安全需求的基础上,提出了一种基于Weil Pairing和连分式插值的组密钥管理方案。该方案充分利用了组播的优势和效率,使得组密钥的分发和更新有很快的速度,提高了组密钥的管理效率。并且满足前向保密、后向保密和抗同谋破解等组播安全性要求,加强了组播安全。同时也具有良好的可扩展性。In order to make good use of the advantages of muhicast and enhance the security and efficiency of key management, a improved multicast key management schema was proposed. It could satisfy both forward and backward confidentiality. Actually it also been showed that the schema has a strong resistance of attacks. This secure multicast key management schema is extensible and could be used in diversified environment.
