Efficient group key agreement & recovery in ad hoc networks
Nikos Komninos, Γεώργιος Μαντάς · 2008
Ad hoc networks are dynamic peer-to-peer wireless networks composed of a collection of nodes which employ wireless transmission methods in a self-organized way without relying on fixed infrastructure or predetermined connectivity. Such networks pose great challenges in group communication. In this paper, we propose an efficient group key agreement and recovery mechanism based on key escrow systems for ad hoc networks. Nodes randomly change their operation and perform authentication services for specific groups.
