Approximate Trapdoors for Lattices and Smaller Hash-and-Sign Signatures
Digital Signature Lattice
2019/9/16
We study a relaxed notion of lattice trapdoor called approximate trapdoor, which is defined to be able to invert Ajtai's one-way function approximately instead of exactly. The primary motivation of ou...
One Bit is All It Takes: A Devastating Timing Attack on BLISS’s Non-Constant Time Sign Flips
Lattice-Based Cryptography Cryptanalysis BLISS
2019/8/7
As one of the most efficient lattice-based signature schemes, and one of the only ones to have seen deployment beyond an academic setting (e.g., as part of the VPN software suite strongSwan), BLISS ha...
Cryptography with quantum states exhibits a number of surprising and counterintuitive features. In a 2002 work, Barnum et al. argued informally that these strange features should imply that digital si...
EVALUATION OF A TRAFFIC SIGN DETECTOR BY SYNTHETIC IMAGE DATA FOR ADVANCED DRIVER ASSISTANCE SYSTEMS
Scene Understanding Traffic Sign Detection Machine Learning Neural Network Synthetic Images
2018/6/4
Recently, several synthetic image datasets of street scenes have been published. These datasets contain various traffic signs and can therefore be used to train and test machine learning-based traffic...

Virtual Smart Cards: How to Sign with a Password and a Server
client-side cryptography consumer devices
2015/12/21
An important shortcoming of client-side cryptography on
consumer devices is the poor protection of secret keys. Encrypting the
keys under a human-memorizable password hardly offers any protection
