Blockchain and other Distributed Ledger Technologies (DLTs) have evolved significantly in
the last years and their use has been suggested for numerous applications due to their …

The advent of quantum computing threatens to break many classical cryptographic
schemes, leading to innovations in public key cryptography that focus on post-quantum …

Rapid advances in quantum computing, together with the announcement by the National
Institute of Standards and Technology (NIST) to define new standards for digitalsignature …

Abstract The Fujisaki-Okamoto (FO) transformation (CRYPTO 1999 and Journal of
Cryptology 2013) turns any weakly secure public-key encryption scheme into a strongly (ie …

At IEEE Security & Privacy 2015, Bos, Costello, Naehrig, and Stebila proposed an
instantiation of Peikert's ring-learning-with-errors–based (Ring-LWE) key exchange protocol …

In this paper, we introduce Saber, a package of cryptographic primitives whose security
relies on the hardness of the Module Learning With Rounding problem (Mod-LWR). We first …

Although quantum computing is still in its nascent age, its evolution threatens the most
popular public-key encryption systems. Such systems are essential for today's Internet …

Cryptography is essential for the security of online communication, cars and implanted
medical devices. However, many commonly used cryptosystems will be completely broken …

Lattice-based cryptography, as an active branch of post-quantum cryptography (PQC), has
drawn great attention from side-channel analysis researchers in recent years. Despite the …

The subfield attack exploits the presence of a subfield to solve overstretched versions of the
NTRU assumption: norming the public key h down to a subfield may lead to an easier lattice …
