QRIS and GOST: A Symbiotic Approach for Secure QR Code Transactions

This study investigates using the GOST encryption algorithm to enhance security within QRCode Indonesia Standard (QRIS). Given ubiquity of QR Codes in digital transactions, particularly for Micro, Small, and Medium Enterprises (MSMEs), robust measures are paramount. We evaluated algorithm’s ability secure data Code, converting code into an encrypted carrier decipherable only via a specially-equipped Code reader. Our findings reveal that presents potent defence mechanism against potential malicious attacks, offering promising path enhancement. However, comprehensive application this measure QRIS poses challenges, including need specialized reader applications broader understanding procedures. Future research opportunities lie optimizing processes, exploring alternative algorithms, developing user-friendly, applications, which could ultimately support more standard usage.
