The rapid development of quantum technologies is reshaping how we think about the security of modern cryptography. This bachelor’s thesis examines how the emerging era of practical quantum computers may affect current cryptographic systems, particularly in the highly sensitive domain of payment technologies. It focuses on technologies that currently dominate the payment ecosystem — EMV chips and RSA-based infrastructures — and demonstrates that these long-standing foundations may become vulnerable to future quantum attacks. The thesis reviews the current state of cryptography used in payment cards and other payment methods, identifies their weaknesses in the context of quantum computing, and analyzes how the industry is responding to these challenges. The practical part of the thesis includes the implementation of a demonstration application simulating a payment transaction scenario. Within the experimental section, the RSA, ML-DSA-44, and SLH-DSA algorithms are implemented and compared in terms of cryptographic operation performance, key sizes, and digital signature sizes.

Process of defence
Student prezentoval výsledky své práce a komise byla seznámena s posudky. Student obhájil bakalářskou práci s výhradami a odpověděl na otázky členů komise a oponenta. Během obhajoby vyvstaly pochybnosti o důsledné práci se zdroji a rozsahu použití generativní umělé inteligence při vytváření textu teoretické části, které student nebyl s to dostatečně rozptýlit.
