Privacy Leakages in Approximate Adders
Shahrzad Keshavarz, Daniel Holcomb
Approximate computing has recently emerged as a promising method to meet the low power requirements of digital designs. The erroneous outputs produced in approximate computing can…
SAT-based Reverse Engineering of Gate-Level Schematics using Fault Injection and Probing
Shahrzad Keshavarz, Falk Schellenberg, Bastian Richter +2
Gate camouflaging is a known security enhancement technique that tries to thwart reverse engineering by hiding the functions of gates or the connections between them. A number of w…
Threshold-based Obfuscated Keys with Quantifiable Security against Invasive Readout
Shahrzad Keshavarz, Daniel Holcomb
Advances in reverse engineering make it challenging to deploy any on-chip information in a way that is hidden from a determined attacker. A variety of techniques have been proposed…
Design Automation for Obfuscated Circuits with Multiple Viable Functions
Shahrzad Keshavarz, Christof Paar, Daniel Holcomb
Gate camouflaging is a technique for obfuscating the function of a circuit against reverse engineering attacks. However, if an adversary has pre-existing knowledge about the set of…
