The authors consider several distributed collaborative key agreement and authentication protocols for dynamic peer groups. There are several important characteristics which make this problem 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 may leave the group while new members may join.
