Quantum Blockchain Architecture for Military Internet of Things

Abstract

In a world rapidly shaped by the ascent of Quantum Computing, the cybersecurity ecosystem confronts unprecedented challenges. The immense computational power of Quantum Computers (QCs) threatens the security of classical cryptographic methods used in both military systems and blockchain technology. This study takes a comprehensive review of Post-Quantum (PQ) Cryptosystems within the context of blockchain by delving into existing schemes around dynamic shifts for security requirements, and performance criteria for quantum-secure systems. The research investigates the vulnerabilities of QC poses to current military systems and presents strategies to prevent the potential effects of attacks by emphasizing the creation of secure systems against quantum attacks. In addition, operational challenges of blockchain in the Quantum Age (QA) are assessed through a comparison with current challenges based on NIST Quantum Challenge Algorithms. Finally, Private Authentication for Rotational Secrecy (PARS) Protocol is proposed for Internet of Military Things Based Quantum Blockchain (IoMT-QB), MiliChain, which bolster secure message exchange of military systems in a quantum-threat environment.
