Post-Quantum Security Enhancements for the TRISA Framework: A Technical Perspective

Abstract

This paper presents a comprehensive technical analysis of the Travel Rule Information Sharing Architecture (TRISA), a compliance framework designed to facilitate secure and privacy-preserving exchange of identity information between Virtual Asset Service Providers (VASPs) in accordance with the Financial Action Task Force (FATF) Travel Rule. We highlight the emerging threat posed by quantum computing to TRISA's current cryptographic mechanisms, including RSA and ECDSA, which underpin identity verification, secure communication, and data confidentiality. To address these vulnerabilities, we propose a migration path integrating post-quantum cryptographic primitives standardized by NIST, specifically CRYSTALS-Kyber for key encapsulation and CRYSTALS-Dilithium for digital signatures. Our approach ensures the preservation of confidentiality, integrity, authenticity, and non-repudiation in the quantum era, enabling TRISA to maintain regulatory compliance and trustworthiness. This work fills a critical gap in adapting specialized compliance architectures to the post-quantum landscape, providing practical recommendations for upgrading TRISA's cryptographic infrastructure to withstand quantum attacks.
