• 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 …

A recent security model for fully homomorphic encryption (FHE), called IND-CPAD security
and introduced by Li and Micciancio [Eurocrypt'21], strengthens IND-CPA security by giving …

Polynomial multiplication algorithms such as Toom-Cook and the Number Theoretic
Transform are fundamental building blocks for lattice-based post-quantum cryptography. In …

In this work, we recover the private key material of the FrodoKEM key exchange mechanism
as submitted to the NIST Post Quantum Cryptography (PQC) standardization process. The …

In this survey, the authors review the main quantum algorithms for solving the computational
problems that serve as hardness assumptions for cryptosystem. To this end, the authors …

We propose the signature scheme Hawk, a concrete instantiation of proposals to use the
Lattice Isomorphism Problem (LIP) as a foundation for cryptography that focuses on …

In this work, we are concerned with the hardening of post-quantum key encapsulation
mechanisms (KEM) against side-channel attacks, with a focus on the comparison operation …
