Optically induced static power in combinational logic: Vulnerabilities and countermeasures
Original language description
Physical attacks, namely invasive, observation, and combined, represent a great challenge for today's digital design. Successful class of strategies adopted by industry, allowing hiding data dependency of the side channel emissions in CMOS is based on balancing. Although attacks on CMOS dynamic power represent a class of state-of-the-art attacks, vulnerabilities exploiting data dependency in CMOS static power and light-modulated static power were recently presented. In this paper, we describe structures and techniques developed to enhance and balance the power imprint of the traditional static CMOS bulk structures under invasive light attack. The novel standard cells designed according to the presented techniques in the TSMC180nm technology node were used to synthesize the dual-rail AES SBOX block. The behavior of the AES SBOX block composed of the novel cells is compared to classical approaches. Usage of novel cells enhances circuit security under invasive light attack while preserving comparable circuit resistance against state-of-the-art power attacks.
