In this paper, we show a very efficient side channel attack against HMAC. Our attack assumes the presence of a side channel that reveals the Hamming distance of some registers. Aft...

Tamper-proof devices are pretty powerful. They can be used to have better security in applications. In this work we observe that they can also be maliciously used in order to defea...
