Paradigm of Post-quantum Cryptography and Crypto-agility: Strategy Approach of Quantum-safe Techniques

Abstract

General security protocols use cryptographic schemes which are not prepared against quantum attacks. Asymmetric public key cryptographic schemes based on well researched methods are defined as broken, from quantum computer perspective. In contrast, symmetric cryptographic schemes and there methods are considered quantum-safe. A new effective strategy is necessary with focusing on post-quantum cryptography for evaluating and researching new quantum-safe cryptographic principles and crypto-agility to update vulnerable security protocols.
