Single-Trace Side-Channel Attacks on ω-Small Polynomial Sampling: With Applications to NTRU, NTRU Prime, and CRYSTALS-DILITHIUM [PDF]
, 2022 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 CRYSTALS-DILITHIUM algorithm implementations (which are NIST Round-3 finalists and ...

Find the Bad Apples: An efficient method for perfect key recovery under imperfect SCA oracles – A case study of Kyber [PDF]
, 2022 Side-channel resilience is a crucial feature when assessing whether a postquantum cryptographic proposal is sufficiently mature to be deployed. In this paper, we propose a generic and efficient adaptive approach to improve the sample complexity (i.e ...

Quantifying risks in cryptographic selection processes [PDF]
, 2023 There appears to be a widespread belief that some processes of selecting cryptosystems are less risky than other processes. As a case study of quantifying the difference in risks, this paper compares the currently-known-failure rates of three large ...

Quantum Key Search for Ternary LWE [PDF]
, 2021 Ternary LWE, i.e., LWE with coefficients of the secret and the error vectors taken from $\{-1, 0, 1\}$, is a popular choice among NTRU-type cryptosystems and some signatures schemes like BLISS and GLP.

NTRU-LPR IND-CPA: A New Ideal Lattices-based Scheme [PDF]
, 2018 In this paper, we propose NTRU-LPR IND-CPA, a new secure scheme based on the decisional variant of Bounded Distance Decoding problem over rings (DR-BDD). This scheme is IND-CPA secure and has two KEM variants IND-CCA2 secure in the random oracle model.
