Local Authentication Unit (LAU) application secures the messages during transfer between the back office (BO) application and the SAA. It is quick to implement and maintain and it requires minimum changes on the level of the BO application.
AEG LAU application is a tool to calculate the Local Authentication Unit for a message to authenticate it with the SWIFT interface. It can be called by the back-office applications to calculate and insert the LAU into the SWIFT message trailer or to check the correctness of received LAU codes.
How it works
It is an application-to-application authentication solution. The first application authenticates the batch generated from its side with a HASH. The corresponding application verifies this HASH, uploads the file in case the HASH is valid or else wise rejects it.
