Abstract:
1. A method for re-establishing secure communications between a node and an endpoint node including the steps of: copying, responsive to a reset at the node, a set of security associations stored in a memory to a working set of security associations, wherein the set of security associations includes only the security associations for a set of trusted endpoint nodes, the set of trusted endpoint nodes determined according to a security association re-use policy of the node, wherein the security association re-use policy controls the set of trusted endpoints to comprise only end-points that are known to the node and communicate with the node on a regular basis; receiving, at the node, a communication from the endpoint node; determining whether a security association for the endpoint node is included in the working set of security associations; responsive to a determination that the security association for the endpoint node is in the working set of security associations, using the security association to process the communication from the endpoint node.
