Design of programmable hardware security modules for enhancing blockchain based security framework

Globalization of the chip design and manufacturing industry has imposed significant threats to hardware security integrated circuits (ICs). It made ICs more susceptible various attacks. Blockchain provides a trustworthy distributed platform store immutable records related evidence intellectual property (IP) creation, authentication provenance, confidential data storage. However, blockchain encounters major challenges due its decentralized nature ledgers that contain sensitive data. The research objective is dedicated programmable modules scheme safeguard maintain information contained in networks context IC supply chain. Thus, framework could rely on proposed separate entire cryptographic operations within system as stand-alone units. This work put forth novel approach be considered utilized enhance real-time. critical components secure hash algorithm-256 (SHA-256) elliptic curve digital signature algorithm are designed entities framework. Physical unclonable functions adopted perform transactions blockchain. Relative comparison with existing works clearly depicts upper hand former terms performance parameters.
