Differential power analysis is a very effective cryptanalysis technique that extracts information on secret keys by monitoring instantaneous power consumption of cryptoprocessors. To protect against differential power analysis, power supply noise is added in cryptographic computations, at the price of an increase in power consumption. We present a novel technique, based on well-known power-reducing transformations coupled with randomized clock gating, that introduces a significant amount of scrambling in the power profile without increasing (and, in some cases, by even reducing) circuit power consumption.

Abstract
Differential power analysis is a very effective cryptanalysis technique that extracts information on secret keys by monitoring instantaneous power consumption of cryptoprocessors. To protect against differential power analysis, power supply noise is added in cryptographic computations, at the price of an increase in power consumption. We present a novel technique, based on well-known power-reducing transformations coupled with randomized clock gating, that introduces a significant amount of scrambling in the power profile without increasing (and, in some cases, by even reducing) circuit power consumption.Pubblicazioni consigliate
