Abstract:
An apparatus, system and method are disclosed to block and replace intermediate combinatorial transitions that are correlated with secret data, also referred to as glitches, with random intermediate combinatorial transitions that are uncorrelated with the data being processed.

Claim (Index 13):
A glitch block circuit for reducing information leakage due to combinatorial logic glitches, consisting of:\n a multiplexer with an input signal that has glitches to be blocked and an uncorrelated signal that can be fixed or variable and a glitch block enable signal; and a one-shot glitch generator consisting of multiplexers in series, wherein the multiplexers use the same select which selects the unpredictable input when one-shot glitches are beneficial to reduce the signal-to-noise ratio (SNR) of the information leakage and the inputs consist of an uncorrelated signal and is any signal that is uncorrelated to the data being processed, wherein the data is a fixed or random value variable and an unpredictable random value input signal is combined with the output of the previous multiplexer in series unless it is the first multiplexer; and an output of the last multiplexer for combining with the functional output wherein the combining causes no functional difference by creating a total combined signal difference of zero.
