This work presents a novel architecture of a high-performance NTT accelerator capable of performing both NTT and inverse NTT operations using a single set of hardware resources.

This work explores several architectural optimizations and proposes a high-performance and area-time (AT) product efficient hardware accelerator for Kyber.

In this paper, we describe the first masked implementation of a lattice-based signature scheme.

In this work, we revisit ARS. Our contributions are threefolds: First, we show that all previous definitions of ARS allow the users’ purchase history to leak.

The main focus of this work is on exploring short pairing-based NIZKs for all NP languages based on standard assumptions.

We introduce a toolkit for transforming lattice-based hash-and-sign signature schemes into masking-friendly signatures secure in the t-probing mod

Threshold signatures improve both availability and security of digital signatures by splitting the signing key into N shares handed out to different parties.

This paper presents Raccoon, a lattice-based signature scheme submitted to the NIST 2022 call for additional post-quantum signatures.

The main purpose of this work is to raise awareness about a primitive that can provide large efficiency gains in post-quantum cryptography: multi-recipient KEMs, ormKEMs.

In this work, we assess the real-world practicality of CSIDH, an isogeny-based non-interactive key exchange.

In this work, we present two round-optimal blind signatures under standard assumptions in the ROM with different approaches: one achieves the smallest sum of the signature and communication sizes, while the other achieves the smallest signature size.

In this paper, we introduce a novel trapdoor generation technique for Prest's hybrid sampler over NTRU lattices.
