Abstract
Security Association (SA) rekeying between two endpoints of a network, is achieved without resorting to a central entity and a separate key management protocol. A packet sent from a first peer to a second peer is modified to add extra data to signal the rekey procedure, and to include cryptographic material to provide a new common keying material, which will be used to create new SAs. Since the rekey procedure is a multi-stage procedure, the peers are assigned (initiator/responder) roles in order to transition from one stage to another. Rekeying may be initiated by a timer present at one of the peers. Embodiments allow network peers to autonomously rekey without the help of a central controller, and each peer can rekey with only N−1 of its peers.
