A 2.5ns-Latency 0.39pJ/b 289µm2/Gb/s Ultra-Light-Weight PRINCE Cryptographic Processor

Abstract : An ultra-light-weight PRINCE cryptographic processor is developed. A fully-unrolled differential-logic architecture saves delay, energy, and area (i.e. hardware weight) of XOR as a dominant cipher component. An S-box is composed only by four kinds of compact composite gates and a replica-delay-based transition-edge aligner prevents glitches accumulated in the long unrolled combinational- logic data path to further suppress the weight. A 28nm CMOS prototype successfully demonstrates 2.5ns-latency with 0.39pJ/b and 289µm 2 /Gb/s of ultra-light-weight cryptographic performance.
