Abstract
Disclosed embodiments implement rekeying keys of a Security Association (SA) using an SPI Transform to provide secure data transfer in a computing environment. A disclosed method comprises detecting, by a local key manager (LKM) executing on a computing node, an expired rekey timer of an SA between an initiator channel on the computing node and a responder channel on a responder node. The LKM requests, based on the expired rekey timer, an SA Index from the initiator channel on a computing node. The LKM creates an SPI based on an SPI Transform using the new SA Index and SPI Transform values. The LKM builds an SKE SA Initialization Request message based on an authentication key of the SA and the SPI to obtain a new session key.
