| 摘 要： | 为了在IP组播中实现用户身份认证等安全管理,避免IP组播中的不安全因素,提出了一种运用门限技术和椭圆曲线密钥体制相结合的方案,构建一个IP组播服务系统并在其上分层实现了组播密钥的分发与恢复。最后通过实验测试给出了此方案的管理代价,证明了此方案可以很好地实现IP组播应用中的密钥管理,有效地解决了用户身份认证和授权管理问题,实现了安全IP组播。

| Abstract: | In order to preserve insecurity factors and accomplish identity certification in IP multicast,this paper proposes a scheme using threshold technology and elliptic curve cryptography.The multicast key distribution and recovery can be achieved by establishing an IP multicast service system.In the end,the paper gives an experiment and discusses the cost of management,which indicates that this scheme can accomplish key management in IP multicast.This scheme solves the problem of user authentication effectively and privilege management and it can achieve secure multicast. |
