High-throughput streaming canonicalization (C14N) and digital signature generation for interbank payment messages.
ISO 20022 replaces legacy MT messaging with verbose XML structures, introducing severe CPU overhead during canonicalization and digital signature generation. FinanceHSM deploys custom hardware XML parsing pipelines that complete canonicalization and signature generation in under 180 microseconds.
FinanceHSM embeds digital signatures directly into the ISO 20022 AppHdr (Business Application Header), ensuring end-to-end cryptographic non-repudiation from the originating commercial bank to the clearinghouse.
