The complexity of the electronics supply chain has grown significantly due to the expansion of globalization in the 21st century. Electronic parts are now manufactured, distributed, and sold globally. Ensuring the security and integrity of the supply chain has become extremely challenging due to the widespread infiltration of untrusted hardware, specifically, counterfeit and cloned parts. Especially, the provenance of microelectronics and commercial off-the-shelf (COTS) parts becomes prohibitively difficult to track and calls for immediate solutions. In this paper, we present a non-destructive way of ensuring the traceability of electronic parts in the supply chain. We have implemented a blockchain-based framework, which helps to track and trace every chip while they are circulating in the supply chain. The proposed framework is built upon a permissioned blockchain. Hyperledger is used for implementing this framework. A detailed analysis is carried out to present the feasibility of our proposed approach.
