Generation of a secure key exchange authentication request in a computing environment

A computer-implemented method of facilitating processing within a computing environment, the computer-implemented method comprising:

• receiving an initialization response message at a local key manager (LKM) executing on an initiator node, the initialization response message sent from an initiator channel on the initiator node in response to a responder channel on a responder node sending the initialization response message to the initiator channel to initiate a secure communication;
• deriving a set of cryptographic keys based on a security association payload of the initialization response message;
• building a proposal list based on one or more security capabilities supported by the initiator channel;
• building an authentication request message based at least in part on the set of cryptographic keys and the proposal list;
• and
• sending the authentication request message from the LKM to the initiator channel.

A computer system for facilitating processing within a computing environment, the computer system comprising:

• an initiator node;
• and
• a plurality of channels coupled to the initiator node, wherein the computer system is configured to perform operations comprising:
• receiving an initialization response message at a local key manager (LKM) executing on an initiator node, the initialization response message sent from an initiator channel on the initiator node in response to a responder channel on a responder node sending the initialization response message to the initiator channel to initiate a secure communication;
• deriving a set of cryptographic keys based on a security association payload of the initialization response message;
• building a proposal list based on one or more security capabilities supported by the initiator channel;
• building an authentication request message based at least in part on the set of cryptographic keys and the proposal list;
• and
• sending the authentication request message from the LKM to the initiator channel.
