Optimal Cryptographic Approach Based on Secure Post-Quantum Cryptographic Algorithms and Classical Algorithms

Abstract

Quantum computing is an incipient and exhilarating field of future computing. Classical computers nowadays are susceptible to security threats and attacks. Security is a major concern in communication and data exchange. The existing encryption technologies that use a shared key are thought to be the most dependable means of secure key generation and distribution. The most popular cryptographic algorithm, RSA Algorithm, has been cracked by a quantum computer utilizing Shor's algorithm. Quantum teleportation is an impeccable way by which information and cryptographic keys can be exchanged securely by building potent quantum circuits. This can obviate information from sniffed or interpreted as quantum computing works predicated on the principle of skepticism. This chapter aims at developing an unbreakable secure cryptographic quantum network utilizing quantum circuits for seamless data exchange in virtual networks.
