The globalization of the semiconductor foundry business poses grave risks in terms of intellectual property (IP) protection, especially for critical applications. Over the past few years, several techniques have been proposed that allow manufacturing of ICs at untrusted foundries by obfuscating and/or locking, albeit at high design overhead, low security(More)
Physically Unclonable Functions (PUFs) were introduced over a decade ago for a variety of security applications. Silicon PUFs exploit uncontrollable random variations from manufacturing to generate unique and random signatures/responses. Existing research on PUFs has focused on either PUF design at the architectural level or optimization of lithography to(More)
IC recycling has become a grave problem in today's globalized semiconductor industry, with potential impact to critical infrastructures. In order to mitigate this problem, various Design-for-Anti-Counterfeit (DfAC) measures have been recently proposed. In this paper, we look at DfAC strategies based on recycling sensors, most notably the ones based on a(More)
