line-height: 18px; text-align: justify;">Our
contribution is twofold: first we describe a very
compact hardware implementation of AES-128, which
requires only 2400 GE. This is to the best of our
knowledge the smallest implementation reported so
far. Then we apply the threshold countermeasure by
Nikova et al. to the AES S-box and yield an
implementation of the AES improving the level of
resistance against first-order side-channel
attacks. Our experimental results on real-world
power traces show that although our implementation
provides additional security, it is still
susceptible to some sophisticated attacks having
enough number of measurements.</span></span>
