| Popis: |
We present the first side-channel attack on a lattice-based signature scheme, using the FLUSH+RELOAD cache-attack. The attack is targeted at the discrete Gaussian sampler, an important step in the Bimodal Lattice Signature Schemes (BLISS). After observing only 450 signatures with a perfect side-channel, an attacker is able to extract the secret BLISS-key in less than 2 minutes, with a success probability of 0.96. Similar results are achieved in a proof-of-concept implementation using the FLUSH+RELOAD technique with less than 3500 signatures. |
