Book ChapterDOI
Successfully attacking masked AES hardware implementations
TL;DR: It turns out that masking the AES S-Boxes does not prevent DPA attacks, if glitches occur in the circuit.
Book ChapterDOI
A side-channel analysis resistant description of the AES s-box
TL;DR: This article introduces a new masking countermeasure which is not only secure against first-order side-channel attacks, but which also leads to relatively small implementations compared to other masking schemes implemented in dedicated hardware.
Journal Article
Analysis of step-reduced SHA-256
TL;DR: In this paper, the authors analyzed the security of SHA-256 against fast collision search and showed that the low probability of a single local collision may give rise to a false sense of security.
Book ChapterDOI
Exploiting coding theory for collision attacks on SHA-1
TL;DR: It is shown that coding theory can be exploited efficiently for the cryptanalysis of hash functions and the complexity for a collision attack on the full SHA-1 is conjecture.
Journal Article
Efficient AES implementations on ASICs and FPGAs
TL;DR: In this paper, two AES hardware architectures for ASICs and FPGAs are presented, one for full-custom as well as for semi-custom design flows, and one for the FPGA implementation does not require on-chip block RAMs.
