Title:
Hybrid Memristor-CMOS Obfuscation Against Untrusted Foundries
Authors: Amin Rezaei, Jie Gu, Hai Zhou
Abstract:The high cost of IC design has made chip protection one of the first priorities of the semiconductor industry. In addition, with the growing number of untrusted foundries, the possibility of inside foundry attack is escalating. However, by taking advantage of polymorphic gates, the layouts of the circuits with different functionalities look exactly identical, making it impossible even for an inside foundry attacker to distinguish the defined functionality of an IC by looking at its layout. Moreover, since memristor is compatible with CMOS structure, it is possible to efficiently design hybrid memristor- CMOS circuits. In this paper, we propose a hardware obfuscation method based on polymorphic hybrid memristor-CMOS technology. Overhead of the polymorphic designs and the time complexity of possible attacks are discussed.
