A Group Key Agreement Protocol Based on Tree and Threshold Idea
Zhiwei Wang, Dawu Gu · 2004
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.
