2010年8月31日 · This article proposes Proof-carrying Hardware (PCH) as a novel approach to bring formal verification to hardware security for reconfigurable platforms. The Proof-carrying Hardware combines a hardware module and a formal proof of safety which adheres to a previously established safety policy.

A comprehensive Proof-Carrying Hardware (PCH) based system level formal solution to evaluate the hardware trust and to further protect the entire hardware and software system. Combines an automated model checker with an interactive theorem prover to reduce the time for proving system-level security properties of SoC’s.

2014年10月15日 · Proof-carrying hardware (PCH) is an approach to achieving safety of dynamically reconfigurable hardware, transferring the idea of proof-carrying code to the hardware domain. Current PCH approaches are, however, either limited to combinational and bounded unfoldings of sequential circuits, or only provide semi-automatic proof generation.

We propose a new approach to PCH which employs IC3 as proof gen-erator, making automatic PCH applicable to sequential circuits in their full generality. We demonstrate feasibility of our approach by showing that proof validation is several orders of magnitude faster than origi-nal proof generation while (most often) generating smaller proofs than

2024年6月25日 · On hardware, and IP cores, author Yier Jin et al. developed a novel proof-carrying hardware (PCH) system [2, 60]. Also, for IP trustworthiness assessment, offer a formal protection strategy based on SAT solvers. Depending on the PCH framework, a new trustworthy IP gathering and delivery protocol is proposed .

PCH takes a key concept from software security, known as proof-carrying code, into the reconfigurable hardware domain. We outline the PCH concept and discuss runtime combinational equivalence checking as a first verification problem applying the concept.

2017年7月20日 · In this article, we present a novel technology for PCH based on inductive invariants. For sequential circuits, our approach is fundamentally stronger than the previous SAT-based one since we avoid the limitations of bounded unrolling. We contrast our technology to existing ones and show that it fits into previously proposed tool flows.

2017年1月3日 · Among all the proposed formal methods, proof-carrying hardware (PCH), which originated from proof-carrying code (PCC), emerged as one of the most prevalent methods for certifying the absence of malicious logic in soft IP cores and reconfigurable logic [6–10].
