We focus on the problem of distributing key updates in secure dynamic groups. Due to changes in group membership, the group controller needs to change and distribute the keys used...
We consider several distributed collaborative key agreement protocols for dynamic peer groups. This problem has several important characteristics which make it different from trad...
