SAP BCM to SWIFT integration file security

Hi,

We are integrating SAP BCM with SWIFT via SAP PI using "SAP Integration Package for SWIFT".

We are generating XMLv2 file (FIN MT101 format) from BCM & sending to SWIFT via PI, while sending to SWIFT,
we need to use the local security (Local Authentication) for the file before sending to SWIFT.

Let me know which Service interface to use & how to and which adapter modules to use in sender & receiver CC.

Please help if anyone has done this.

thnx in adv,
rgds,
