Abstract
Aspects of the invention include detecting that a rekey timer has expired. The rekey timer is one of a shared key rekey timer for a current shared key between the first node and a second node, and a session key rekey timer for a session key used in a secure communication between a channel on the first node and a channel on the second node. The session key was created based on the current shared key and is used for encrypting data in the secure communication. Based on the rekey timer being the shared key rekey timer, a new shared key is obtained and stored as the current shared key. Based on the rekey timer being the session key rekey timer, a new session key that is based at least in part on the current shared key is obtained and used in the secure communication.
