Single-Trace Attack on NIST Round 3 Candidate Dilithium Using Machine Learning-Based Profiling

IEEE Access, 2021
In this paper, we propose single-trace side-channel attacks against $\mathsf {CRYSTALS{-}DILITHIUM}$ . $\mathsf {CRYSTALS{-}DILITHIUM}$ is a lattice-based digital signature algorithm, one of the third round finalists of the national institute of ...

Heterogeneous Reconfigurable Accelerator for Homomorphic Evaluation on Encrypted Data

IEEE Access
Homomorphic encryption (HE) enables third-party servers to perform computations on encrypted user data while preserving privacy. Although conceptually attractive, the speed of software implementations of HE is almost impractical.

Multiscale Granger causality analysis by \`a trous wavelet transform

, 2017
Since interactions in neural systems occur across multiple temporal scales, it is likely that information flow will exhibit a multiscale structure, thus requiring a multiscale generalization of classical temporal precedence causality analysis like ...
