To appear.Abstract
This paper presents an integrated sense-and-react countermeasure for a Shared Group Key (SGK) system. 1) A set of fully CMOS-compatible integrated sensors detects multimodal physical attacks exploiting direct-probing, side channel, and laser-injection from both front- and back-side of a silicon chip. 2) Upon the attack detection, the system immediately updates SGK based on the detailed attack information obtained by the sensor for reactive SGK protection. Prototype test-chip measurements successfully demonstrate the double-sided multimodal attack detection and counter-reaction capability with small hardware overhead for future resource-constrained information systems.
