Webicantly smaller than the previous Keccak implementations and have higher frequency. Moreover, the threshold implementations with serial architecture can be considered within the limits of a lightweight imple-mentation. In addition, we discuss a way to reduce the area cost of the threshold implementations at the cost of extra randomness. First ... Web5 de dez. de 2024 · Abstract: Threshold Implementation (TI) is one of the most widely used countermeasure for side channel attacks. Over the years several TI techniques have been proposed for randomizing cipher execution using different variations of secret-sharing and implementation techniques.
