Abstract
A shared key, used by one node and another node of a computing environment in authentication of one or more links coupling the one node and the other node, is determined to be within an expiration range. Based on determining the shared key is within the expiration range, re-authentication of at least one link is automatically initiated. The automatically initiating re-authentication includes obtaining, by the one node, a new shared key from a key server, sending a message encrypted with the new shared key from the one node to the other node via one link of the one or more links, and receiving by the one node via the one link an indication that the other node decrypted the message using the new shared key.
