Abstract

Security is a concern in the design of smartcards. It is possible to leak much side channel information related to secret key when cryptographic algorithm runs on smartcards. Power analysis attacks are a very strong cryptanalysis by monitoring and analyzing power consumption traces. In this paper, we experiment Exclusive OR operation. We also analyze the tendency of state-of-the-art regarding hardware countermeasures and experiments of Hamming-Weights on power attacks. It can be useful to evaluate a cryptosystem related with hardware security technology.
