The urgent requests to protection integrated circuits (IC) and hardware intellectual properties (IP) have led to the development of various logic obfuscation methods. While most existing solutions focus on the combinational logic or sequential logic with full scan-chains, in this paper, we will revisit the security of sequential logic obfuscation within circuits where full scan-chains are not available...
The heavy reliance on third-party resources, including third-party IP cores and fabrication foundries, has triggered the security concerns that design backdoors and/or hardware Trojans may be inserted into fabricated chips. While existing reverse engineering tools can help recover netlist from fabricated chips, there is a lack of efficient tools to further analyze the netlist for malicious logic detection...
In a modern IC design flow, from specification development to chip fabrication, various security threats are emergent. Of particular concern are modifications made to third-party IP cores and commercial off-the-shelf (COTS) chips where no golden models are available for comparisons. Toward this direction, we develop a tool, named Reverse Engineering Finite State Machine (REFSM), that helps end-users...
