The Future of Encryption in the Face of Advancing Quantum Computing Technology

Abstract

Quantum computing is an emerging technology that significantly reduces calculation and processing time. Unlike classical computers that use binary bits with two states (0 or 1), quantum computers use qubits that can exist in two states simultaneously, known as superposition. Shor’s algorithm takes advantage of quantum parallelism to easily break RSA encryption algorithms, which are widely used in modern online services and encryption. This presents a threat to personal information and data security. This paper discusses the threat of quantum computing to current encryption algorithms and proposes new algorithms to prevent it.
