Abstract
A hardware-based and software-based method for enhancing resistance against side-channel attacks in a cryptosystem that includes providing a current internal state memory with a segment of randomized data and operating within a cryptosystem, receiving leaky external data and the segment of randomized data from the current internal state memory at a randomizer module, and randomizing the leaky external data with the randomizer module utilizing the segment of randomized data from the current internal state memory to generate a randomized representation of the leaky external data as a data input for a crypto operation within the cryptosystem.
