Profiling Side-Channel Attacks on Dilithium
We present an end-to-end (equivalent) key recovery attack on the Dilithium lattice-based signature scheme, one of the winners of the NIST postquantum cryptography competition. The attack is based on a small side-channel leakage we identified in a bit unpacking procedure inside Dilithium signature generation.Ulitzsch, Vincent Quentin +3 more

Side Channel Attacks and Countermeasures
2011Side-channel attacks bypass the theoretical strength of cryptographic algorithms by exploiting weaknesses in the cryptographic system hardware implementation via nonprimary, side-channel inputs and outputs. Commonly exploited side-channel outputs include: power consumption, electromagnetic (EM) emissions, light, timing, and sound (Fig. 8.1).

Introduction to Side-Channel Attacks
2009Side-channel cryptanalysis is a new research area in applied cryptography that has gained more and more interest since the mid-nineties. It considers adversaries trying to take advantage of the physical specificities of actual cryptographic devices. These implementation-specific attacks frequently turn out to be much more efficient than the best known ...
