Hardware countermeasure against cryptographic attack

摘要

A hardware countermeasure for a cryptographic hardware module of a computing device is provided. The hardware countermeasure may include a noise-sample generator and a distributed buffer network co-located with the cryptographic module. The noise-sample generator may take as input data samples to be processed by the cryptographic hardware module and generate as output a non-Gaussian noise-sample for each of the input data samples. The distributed buffer network may take as input the non-Gaussian noise-samples and generate a non-Gaussian noise output corresponding to each of the non-Gaussian noise-samples.
