ONE-BIT TO FOUR-BIT DUAL CONVERSION APPARATUS FOR ENHANCED SECURITY AGAINST SIDE CHANNEL ANALYSIS AND METHOD THEREOF

摘要

The present invention relates to a dual conversion apparatus for preventing a side channel analysis comprising: a microcontroller converting each of 1 bit representations, expressed by 0 and 1, into one of two 4 bit conversions respectively, reconstructing an encryption algorithm, and applying the dual 4 bit conversion to the reconstructed encryption algorithm; and a storage unit storing the dual 4 bit conversion performed by the microcontroller.
