Key randomization using a power analysis resistant deterministic random bit generator
Paul Duplys, Eberhard Bohl, Wolfgang Rosenstiel · 2010
Hardware as well as software implementations of cryptographic algorithms are susceptible to power analysis attacks. Power analysis attacks exploit the dependence of the power consumption of a CMOS circuit on the data the circuit processes. We propose a power analysis-resistant deterministic random bit generator that operates on internal states with constant Hamming distance and Hamming weight.
