Trace Logic Locking: Improving the Parametric Space of Logic Locking
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2021To protect against an untrusted foundry, logic locking must 1) inject sufficient error to ensure critical application failures for any wrong key (error severity) and 2) resist any attack against it (attack resilient). We begin our work by deriving a fundamental tradeoff between these two goals which exists underlying all logic locking, regardless of ...

Provably-Secure Logic Locking: From Theory To Practice
Proceedings of the 2017 ACM SIGSAC Conference on Computer and Communications Security, 2017Logic locking has been conceived as a promising proactive defense strategy against intellectual property (IP) piracy, counterfeiting, hardware Trojans, reverse engineering, and overbuilding attacks. Yet, various attacks that use a working chip as an oracle have been launched on logic locking to successfully retrieve its secret key, undermining the ...

Redundancy Attack: Breaking Logic Locking Through Oracleless Rationality Analysis
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2023During the last decade, logic locking has been proposed to protect integrated circuits against piracy and reverse engineering threats. Functional pruning attacks, such as the Boolean satisfiability (SAT) attack, have greatly challenged the security of ...

SheLL: Shrinking eFPGA Fabrics for Logic Locking
Design, Automation and Test in Europe, 2023The utilization of fully reconfigurable logic and routing modules may be considered as one potential and even provably resilient technique against intellectual property (IP) piracy and integrated circuits (IC) overproduction. The embedded FPGA (eFPGA) is
