A Novel Model for Resisting Side Channel Attack by Masking of Gates

Abstract

The XOR gate is often used in cryptography modules. These cells' hardware implementations are subject to power analysis attacks. Correlation power attacks (CPAs) allow an attacker to estimate a highly correlated hypothetical value from the actual hidden value. By masking the input and unmaking the output, the present countermeasure technology randomises the power consumption pattern and increases the number of cells. We proposed the mask XOR gate in this study because they do not require cell unmasking and demonstrate a smaller correlation between power traces and input data.
