A Configurable Dual-Mode PRINCE Cipher with Security Aware Pipelining in 65nm for High Throughput Applications

Abstract

A dual-mode PRINCE encryption cipher is implemented, in 65nm technology, that is configurable between pipelined and fully unrolled modes. Correlation Power and EM analysis on test-chip measurements show minimal exploitability of leakage from intermediate registers in pipelined mode. The pipelined PRINCE designs are seen to exhibit similar side channel resistance to unrolled designs while providing higher frequency and throughput. The overall dual-mode system has a minimum MTD of 460K and a projected maximum throughput of 492 Mega encryptions per second.
