Abstract
Embodiments of the present disclosure provide systems and methods for generating a secure key exchange (SKE) Authentication Request using a Security Parameter Index (SPI) Transform to provide secure data transfer in a computing environment. A disclosed method comprises receiving an SKE SA Initialization Response message at a local key manager (LKM) executing on an initiator node to initiate a secure communication between an initiator channel on the initiator node and a responder channel on a responder node. The LKM creates an SPI based on an SPI Transform using an SA Index and SPI Transform values, and the LKM builds the SKE Authentication Request message, which comprises the SPI, a set of cryptographic keys, and a list of encryption algorithms supported by the initiator channel. The LKM sends the SKE Authentication Request message to the responder channel on the responder node using the initiator channel.
