Abstract
A method and an apparatus for hardware security to countermeasure side-channel attacks are provided. The method or apparatus may introduce at least one redundant or partial redundant computation having a similar power dissipation profile or an electromagnetic emission profile when compared to that of a genuine operation for cryptographic devices, and/or to reorder the iterations of operations in a different sequence. The redundant or partial redundant computation may be performed by using a different password key and/or a different raw data (e.g., plaintext). The presence of the redundant or partial redundant computation would make side-channel attacks difficult in the sense that genuine or redundant/partial redundant operations are difficult to be clearly identified, hence serving as a countermeasure for hardware security.
