We present GKMPAN, an efficient and scalable group
rekeying protocol for secure multicast in ad hoc networks.
Our protocol exploits the property of ad hoc networks that
each member of a group is both a host and a router, and distributes
the group key to member nodes via a secure hop-by-hop
propagation scheme. A probabilistic scheme based on
pre-deployed symmetric keys is used for implementing secure
channels between members for group key distribution.
GKMPAN also includes a novel distributed scheme for efficiently updating the pre-deployed keys. GKMPAN has three attractive properties. First, it is significantly more efficient
than group rekeying schemes that were adapted from those
proposed for wired networks. Second, GKMPAN has the
property of partial statelessness; that is, a node can decode
the current group key even if it has missed a certain number
of previous group rekeying operations. This makes it very attractive
for ad hoc networks where nodes may lose packets
due to transmission link errors or temporary network partitions.
Third, in GKMPAN the key server does not need any
information about the topology of the ad hoc network or the
geographic location of the members of the group. We study
the security and performance of GKMPAN through detailed
analysis and simulation.
