NTTRU: Truly Fast NTRU Using NTT [PDF]
Transactions on Cryptographic Hardware and Embedded Systems, 2019 We present NTTRU – an IND-CCA2 secure NTRU-based key encapsulation scheme that uses the number theoretic transform (NTT) over the cyclotomic ring Z7681[X]/(X768−X384+1) and produces public keys and ciphertexts of approximately 1.25 KB at the 128-bit ...

Improved Plantard Arithmetic for Lattice-based Cryptography [PDF]
Transactions on Cryptographic Hardware and Embedded Systems, 2022 This paper presents an improved Plantard’s modular arithmetic (Plantard arithmetic) tailored for Lattice-Based Cryptography (LBC). Based on the improved Plantard arithmetic, we present faster implementations of two LBC schemes, Kyber and NTTRU, running ...

Hints from Hertz: Dynamic Frequency Scaling Side-Channel Analysis of Number Theoretic Transform in Lattice-Based KEMs [PDF]
Transactions on Cryptographic Hardware and Embedded SystemsNumber Theoretic Transform (NTT) has been widely used in accelerating computations in lattice-based cryptography. However, attackers can potentially launch power analysis targeting the NTT because it is one of the most time-consuming parts of the ...

Improved Attacks Against Lattice-Based KEMs Using Hints From Hertzbleed [PDF]
Transactions on Cryptographic Hardware and Embedded SystemsThe Number Theoretic Transform (NTT) is widely employed to accelerate computations in lattice-based cryptography. At CHES 2024, Yu et al. introduced a class of side-channel attacks targeting NTT operations in the simplified Kyber and NTTRU schemes ...
