This letter describes a lattice encoder for the NIST-recommended post-quantum encryption
algorithm: Kyber. The key idea is to refine the analysis of Kyber decoding noise. We prove …

More and more electronic devices are connected to the internet. To secure these devices,
designers rely on cryptographic standards that provide encryption, authentication and data …

In this paper, we investigate the communication overhead of the Kyber, which has recently
been standardized by the National Institute of Standards and Technology (NIST). Given the …

We describe new arithmetic coding techniques and side-channel blinding countermeasures
for lattice-based cryptography. Using these techniques, we develop a practical, compact …

Post-Quantum Cryptography has gained attention in the recent years from the research
community due to the disastrous consequences that efficient quantum computers would …

NTRUEncrypt, proposed in 1996 by Hoffstein, Pipher and Silverman, is the fastest known
lattice-based encryption scheme. Its moderate key-sizes, excellent asymptotic performance …

The security proofs of post-quantum cryptographic schemes often consider only classical
adversaries. Therefore, whether such schemes are really post-quantum secure remains …

In this paper we investigate the impact of decryption failures on the chosen-ciphertext
security of lattice-based primitives. We discuss a generic framework for secret key recovery …

In some lattice-based cryptosystems, the encryption and decryption processes can be
interpreted as a noisy communication channel. In this work, we focus on cryptosystems …

CRYSTALS-Kyber, as the only public key encryption (PKE) algorithm selected by the
National Institute of Standards and Technology (NIST) in the third round, is considered one …
