A One-Time Single-bit Fault Leaks All Previous NTRU-HRSS Session Keys to a Chosen-Ciphertext Attack [PDF]
IACR Cryptology ePrint Archive, 2022 This paper presents an efficient attack that, in the standard IND-CCA2 attack model plus a one-time single-bit fault, recovers the NTRU-HRSS session key. This type of fault is expected to occur for many users through natural DRAM bit flips.

Small Leaks Sink a Great Ship: An Evaluation of Key Reuse Resilience of PQC Third Round Finalist NTRU-HRSS [PDF]
IACR Cryptology ePrint Archive, 2021 NTRU is regarded as an appealing finalist due to its long history against all known attacks and relatively high efficiency. In the third round of NIST competition, the submitted NTRU cryptosystem is the merger of NTRU-HPS and NTRU-HRSS. In 2019, Ding et al. have analyzed the case when the public key is reused for the original NTRU scheme. However, NTRU-

New NTRU Records with Improved Lattice Bases [PDF]
IACR Cryptology ePrint Archive, 2023 The original NTRU cryptosystem from 1998 can be considered the starting point of the great success story of lattice-based cryptography. Modern NTRU versions like NTRU-HPS and NTRU-HRSS are round-3 finalists in NIST\u27s selection process, and also ...

NTT Multiplication for NTT-unfriendly Rings [PDF]
Transactions on Cryptographic Hardware and Embedded Systems, 2021 In this paper, we show how multiplication for polynomial rings used in the NIST PQC finalists Saber and NTRU can be efficiently implemented using the Number-theoretic transform (NTT).

IET Information Security, Volume 15, Issue 6, Page 472-486, November 2021., 2021 Abstract Multi‐key fully homomorphic encryption (MKFHE) allows computations on ciphertexts encrypted by different users, which can be applied to implement secure multi‐party computing (MPC). The current NTRU‐based MKFHE has the following two drawbacks: One is that the relinearisation process during homomorphic evaluation is so complicated that the ...

Leaking-Cascade: an Optimal Construction for KEM Hybridization [PDF]
, 2023 Hybrid post-quantum cryptography is a cautious approach that aims to guard against the threat posed by the quantum computer, through the simultaneous use of Post-Quantum (PQ) and classical (i.e. pre-quantum) cryptosystems, should the post-quantum schemes
