The lattice-based CRYSTALS-Dilithium scheme is one of the three thirdround digital
signature finalists in the National Institute of Standards and Technology Post-Quantum …

Motivated by the rise of quantum computers, existing public-key cryptosystems are expected
to be replaced by post-quantum schemes in the next decade in billions of devices. To …

This paper proposes a new single-trace side-channel attack on lattice-based post-quantum
protocols. We target the ω-small polynomial sampling of NTRU, NTRU Prime, and …

Key exchange protocols and key encapsulation mechanisms establish secret keys to
communicate digital information confidentially over public channels. Lattice-based …

This paper presents a new profiling side-channel attack on CRYSTALS-Dilithium, the new
NIST primary standard for quantum-safe digital signatures. An open-source implementation …

Post-quantum digital signature is a critical primitive of computer security in the era of
quantum hegemony. As a finalist of the post-quantum cryptography standardization process …

Lattice-based cryptographic schemes such as Crystals-Kyber and Dilithium are post-
quantum algorithms selected to be standardized by NIST as they are considered to be …

Quantum computing utilizes properties of quantum physics to build a fast-computing
machine that can perform quantum computations. This will eventually lead to faster and …

Homomorphic encryption (HE) allows computing encrypted data in the ciphertext domain
without knowing the encryption key. It is possible, however, to break fully homomorphic …

This paper demonstrates the first side-channel attack on homomorphic encryption (HE),
which allows computing on encrypted data. We reveal a power-based side-channel leakage …
