PROSPECTS AND PRACTICAL SOLUTIONS OF POST-QUANTUM CRYPTOGRAPHY

Abstract

With the rapid advancement of information technologies, cybersecurity threats are increasing at an alarming rate. In particular, the emergence of quantum computers poses a serious risk to traditional cryptographic algorithms such as RSA, ECC, and DSA, which rely on mathematical problems that are difficult to solve using classical computing. However, these same problems can be efficiently solved on a quantum computer using Shor’s algorithm, thus endangering the security of nearly all current public-key cryptosystems. In response, the concept of Post-Quantum Cryptography (PQC) is gaining global attention as a future-proof solution.
