Establishes node-to-node initialization between payment processing nodes such as an acquirer, issuer or payment network using Australian Standard 2805 (AS2805).
During node-to-node initialization, both communicating nodes must validate that they possess the correct Key Encrypting Keys (KEKs) before proceeding with session key exchange. In AS2805, the sending KEK (KEKs) of one node corresponds to the receiving KEK (KEKr) of its partner node. Each node uses its KEK to encrypt and decrypt session keys exchanged between the nodes. A KEK can be created or imported into Amazon Web Services Payment Cryptography using either the
CreateKey or
ImportKey operations.
The node initiating communication can use
GenerateAS2805KekValidation to generate a combined KEK validation request and KEK validation response to send to the partnering node for validation. When invoked, the API internally generates a random sending key encrypted under KEKs and provides a receiving key encrypted under KEKr as response. The initiating node sends the response returned by this API to its partner for validation.

Key types for specific data operations in the
Amazon Web Services Payment Cryptography User Guide.
Cross-account use: This operation can't be used across different Amazon Web Services accounts.
