Resilient Uniformity: Applying Resiliency in Masking

Siemen Dhooghe and Svetla Nikova

Abstract: Threshold Implementations are known countermeasures defending against side-channel attacks via the use of masking techniques. While sufficient properties are known to defend against first-order side-channel attacks, it is not known how to achieve higher-order security. This work generalizes the Threshold Implementation notion of uniformity and proves it achieves second-order protection. The notion is applied to create a second-order masking of the PRESENT cipher with a low randomness cost.
