Abstract
Systems and methods are disclosed for acknowledgement-based retirement of expired secure association keys (SAK). A new SAK is generated by a key server. The new SAK is transmitted to members of a connectivity association (CA). The new SAK for key server ingress traffic is installed. An ingress SAK installation acknowledgement is received from the members of the CA. The new SAK for key server egress traffic is installed at the key server, based on receiving the ingress SAK installation acknowledgement from the members of the CA. A key server egress SAK installation notification is transmitted to the members of the CA A prior secure association key is retired after a configurable SAK retirement buffer delay in response to an earlier occurrence of either: receipt of an egress SAK installation acknowledgement from the members of the CA and expiration of a SAK retirement buffer delay, or expiration of a SAK retirement timeout.
