The authors consider several distributed collaborative key agreement protocols for dynamic peer groups. This problem has several important characteristics which make it different from traditional secure group communication. They are distributed nature in which there is no centralized key server, collaborative nature in which the group key is contributory; i.e., each group member will collaboratively contribute its part to the global group key and dynamic nature in which existing members can leave the group while new members may join. Instead of performing individual rekey operations, i.e., re-computing the group key after every join or leave request, they consider an interval-based approach of rekeying.
