An efficient, secure distributed key management scheme ( D-OFT) using a one-way function tree was developed to avoid the single failure point problem and the unfairness in group key generation or refreshment algorithms in centralized group key management schemes.

针对集中式组密钥管理方案具有单失效点和密钥非公平产生等问题提出了一种基于单向函数树的高效分布式组密钥管理方案（D-OFT）。

This strategy uses Chord protocol as group management Protocol in unstructured P2P networks; all replica nodes of the same file form a Chord ring. An update propagation tree is gradually built by continuous dividing the node space in Chord ring.

该策略在无结构P2P网络中使用Chord协议作为组管理协议，同一文件的所有副本所在节点构成一个Chord环，通过不断分割Chord环上副本节点的空间区域，逐渐构建一棵更新传播树。

Then, by blending the bilinear pairing based key agreement with ternary key tree, we present a group key management scheme for high-delay dynamic peer networks, which supports join, leave, merge and partition events.

然后结合基于双线性对的密钥协商和三叉树结构，提出了一种适用于高时延动态对等网的群组密钥管理方案。此方案可以有效地处理成员的加入、离开以及子群的合并、分割事件。
