【摘要】 根据选播组管理的特点,提出了一种安全的分布式解决方案.组成员的加入、退出等操作首先要经过组其他成员的认证,然后由这些成员向各个选播路由器发送相关指令来完成相应的操作.组成员之间的监测采用分组方式进行,成员之间的数据报文以及成员发送到选播服务器的更新报文都采用密文方式进行传输.分析表明,该方案可以满足选播组管理的时延要求.更多还原

【Abstract】 A secure distributed solution is proposed in this paper according to the characteristics of anycast group management.Operations of group member such as joining and exiting are first authenticated by other members of the group.These members send relevant orders to every anycast router to complete the corresponding operations.By dividing members into smaller groups,monitoring between group members is performed.Cipher text is used when datagrams among members and the update message from members to anycast routers are transmitted.The analysis indicates that this scheme can satisfy the delay requirements of anycast group management,and is secure,robust and scalable.更多还原
