The learning with errors (LWE) problem has become a central building block of modern
cryptographic constructions. This work collects and presents hardness results for concrete …

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

Abstract The National Institute of Standards and Technology is in the process of selecting
publickey cryptographic algorithms through a public, competition-like process. The new …

• Increase noise parameter for Kyber512 In the round-2 submission of Kyber, the decryption
error for Kyber512 was rather conservative, while at the same time, there were requests to …

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 …

Many recent private set intersection (PSI) protocols encode input sets as polynomials. We
consider the more general notion of an oblivious key-value store (OKVS), which is a data …

Lattice-based cryptography offers some of the most attractive primitives believed to be
resistant to quantum computers. Following increasing interest from both companies and …

To solve the approximate nearest neighbor search problem (NNS) on the sphere, we
propose a method using locality-sensitive filters (LSF), with the property that nearby vectors …

We consider all LWE-and NTRU-based encryption, key encapsulation, and digital signature
schemes proposed for standardisation as part of the Post-Quantum Cryptography process …

In today Internet era, confidential information transmitted over an insecure channel. With the
significant development in the area of quantum computing, there is a need for unconditional …
