Small Leaks Sink a Great Ship: An Evaluation of Key Reuse Resilience of PQC Third Round Finalist NTRU-HRSS [PDF]
, 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 the NIST competition, the submitted NTRU cryptosystem is the merger of NTRU-HPS and NTRU-HRSS.

Message Recovery Attack in NTRU through VFK Lattices
, 2023 In the present paper, we implement a message recovery attack to all variants of the NTRU cryptosystem. Our approach involves a reduction from the NTRU-lattice to a Voronoi First Kind lattice, enabling the application of a polynomial CVP exact algorithm ...

LWE with Side Information: Attacks and Concrete Security Estimation [PDF]
, 2022 We propose a framework for cryptanalysis of lattice-based schemes, when side information---in the form of ``hints\u27\u27--- about the secret and/or error is available.
