Transforming Military Security: Quantum Age Blockchain Architecture for IoBT - PARS

In a world rapidly shaped by the ascent of Quantum Computing, the blockchain ecosystem confronts unprecedented challenges. The immense computational power of Quantum Computers (QC) poses a threat to classical cryptographic approaches employed by blockchain technology. This study takes a comprehensive view of Post Quantum Cryptosystems within the context of blockchain, delving into existing schemes, security requirements, and dynamic shifts necessary to navigate in the Quantum Era. The research delves into the vulnerabilities QC poses to current blockchain schemes and explores potential mitigation strategies while emphasizing the creation of quantum-secure systems. Additionally, the study includes a comparative analysis of post-quantum cryptography algorithms that could ad-vance next generation blockchain systems. Moreover, 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 Defense Blockchain (IoMT-QDB) which bolster secure message exchange of military systems in a quantum-threat environment.
