Secure Chip To Chip Communication Based On Zero Trust Architecture In Embedded Systems

Abstract

Nowadays, semiconductor companies frequently outsource the production of chips to meet the rising demand for integrated circuits. As a result, the chip supply chain is now dealing with a number of security problems, like hardware intellectual property theft, trojans, and over-production. In critical systems where adversary assaults have the potential to cause large losses or damage, zero-trust offers a promising method for guaranteeing the validity of Integrated Circuits (ICs). A reliable protocol which makes use of certificates to guarantee the legitimacy of ICs is the Security Protocol and Data Model (SPDM). The work under this study presents a secure chip-to-chip (S2C) zero-trust security architecture based on SPDM protocol, which attempts to authenticate any attached peripheral before using it. The contributions include a comprehensive explanation of the proposed design, the SPDM protocol's implementation, and a discussion of the obstacles that were encountered while executing and implementing.
