> 中文摘要: 动态对等通信(dynamic peer communication)是目前最复杂的群组通信方式之一.简要分析了近几年提出的适合这种通信方式的5种组密钥协商协议,即CKD(centralized key distribution)协议、BD(burmester-desmedt)协议、STR(steer,et a1.)协议.GDH(group diffie-hellman)协议和TGDH(tree-based group diffie-hellman)协议,进而提出了一种基于树结构和门限思想的组密钥协商协议TTS(tree and threshold scheme).与现有的协议比较,TTS协议在计算量方面具有较大优势,适用于现有的网络环境.
Abstract:Dynamic peer communication is the most complicated of all the group communication mode. The paper concisely analysed five typical group key agreement protocols put forward in recent years, they are: centralized key distribution (CKD), burmester-desmedt (BD), steer et al. (STR), group diffie-hellman (GDH) and tree-based group diffie-hellman (TGDH). A new group key agreement protocol (TTS) is proposed and compared with other protocols. This protocol has the advantage in computation, and fit to common network condition.
