Using Aqua’s LAU Module, e2gen will transmit messages to the SWIFT device with a Local Authentication signature in the trailer of each SWIFT message. The LAU value depends on 2 16 digit keys that are concatenated to provide a key for the encryption algorithm that uses Hash-Based Message Authentication Code (HMAC) Secure Hash Algorithm (SHA-256) signatures.
The symmetric key is shared by both the back-office application and Alliance Access. For any Incoming SWIFT with an LAU in the header e2gen will verify that the LAU is correct and reject messages where there is no LAU. Similarly the SWIFT device will check the authenticity of the LAU on messages created by e2gen
