移动因特网中安全组播通信的密钥管理研究

Survey on key management for secure multicast communications in mobile Internet

比较了各种确保安全组播通信的密钥管理算法和方案,针对移动环境下移动频繁、可靠性差的特点,讨论了在RingNet结构下移动因特网的组播密钥管理问题。

A survey of many kinds of schemes was present about secure multicast key management. In the meanwhile, in view of mobile environment, frequent handoff and poor reliability are the key properties and differences. Thus the secure multicast key management strategy in mobile Internet was discussed deeply in the survey.
