Date Science: Post Quantum Safe Cryptography

Abstract

New cryptographic techniques have emerged in recent decades that do provide protection against quantum threats. These techniques are termed “postquantum cryptography” and consist of techniques based on quantum properties of light that prevent interception of messages, as well as classic computational techniques, all of which were designed to resist quantum attacks emerging from the rapidly accelerating research field of quantum computation. This paper provides background information on post-quantum security. It explores the security threats against communication security and particularly against key exchange that are enabled by the development of quantum computers. The applied and theoretical aspects of quantum-cryptographic technologies are considered, which is designed to be a reference for those operating in the ICT space in fields other than information security and postquantum cryptography. The interrelated elements that make up the concept and content determined by the application of quantum cryptography are analyzed. The systematic analysis of quantum algorithms, quantum cryptography and quantum hashing are presented. The proper concept vehicle over is brought, in particular the concepts of singularity and supersingularity are determined for elliptic curves and theoretical positions, lyings in their basis, are examined. Terms which must be taken into account at the selection of elliptic curves for cryptographic applications are determined.
