QUANTUM COMPUTING AS A THREAT TO MODERN CRYPTOGRAPHY. AN OVERVIEW OF SHOR'S ALOHORHYTHM AND POST-QUANTUM CRYPTOGRAPHY

The article is devoted to the study of the threat of the development of quantum computing for classical cryptographic systems vulnerable to the Shor algorithm. It is shown that the RSA and ECC protocols lose their stability with the advent of scalable quantum computers, while post-quantum lattice and code schemes demonstrate high stability. It is concluded that there is a need to move to post-quantum standards and develop hybrid cryptosystems.
