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