Abstract
Provided are a computer program product, system, and method embodiments for reverting from a new security association to a previous security association in response to an error during a rekey operation. An initiator maintains a first security association with the responder having a first key to use to encrypt and decrypt data transmitted with the responder. The initiator initiates a rekey operation to establish a second security association with the responder using a second key. The initiator detects a failure of the rekey operation after the responder started using the second key for transmissions. A revert message is sent to the responder to revert back to using the first security association and first key in response to detecting the failure of the rekey operation.
