A Post-quantum Zero-Knowledge Proof System Using Quantum Information Theory

Abstract

In recent decades, the importance of protecting computer systems and networks from information disclosure (relevant to information technology and cybersecurity fields) has risen to the utmost importance. With wide applications in subjects such as voting registration, insurance, credit card information, personal identity security, and as of recently crypto-based blockchains, the field is becoming increasingly significant. Due to the perpetual and expanding reliance on computer systems, the way that we handle and send our data is vital. Improper methods of establishing privacy for secure data transmission can compromise substantial amounts of user data, making the development of high-level privacy-preserving mechanisms impervious to tampering of immense importance. For example, the existence of most cryptographic systems is threatened by the development of quantum computing, and therefore, the development of making post-quantum/quantum-resistant cryptographic systems is in great demand. In this research, unlike most current existing systems, we propose a classical to quantum mapping channel for zero-knowledge that will not be negatively affected by the existence of quantum technologies.
