Will You Cross the Threshold for Me?
Transactions on Cryptographic Hardware and Embedded Systems, 2021 In this work, we propose generic and novel side-channel assisted chosenciphertext attacks on NTRU-based key encapsulation mechanisms (KEMs). These KEMs are IND-CCA secure, that is, they are secure in the chosen-ciphertext model.

Single-Trace Attacks on Message Encoding in Lattice-Based KEMs
IEEE Access, 2020 In this article, we propose single-trace side-channel attacks against lattice-based key encapsulation mechanisms (KEMs) that are the third-round candidates of the national institute of standards and technology (NIST) standardization project. Specifically,

A framework for cryptographic problems from linear algebra
Journal of Mathematical Cryptology, 2020 We introduce a general framework encompassing the main hard problems emerging in lattice-based cryptography, which naturally includes the recently proposed Mersenne prime cryptosystem, but also problems coming from code-based cryptography.

Optimization of NTRU Prime asymmetric encryption algorithm
Radiotekhnika, 2017 The results of algorithms optimization for the post-quantum mechanism of asymmetric encryption NTRU Prime are given. Namely: module reduction, blinding polynomial calculation, encryption and decryption algorithms. A comparative analysis of different polynomials multiplications is also given.

A detailed analysis of the hybrid lattice-reduction and meet-in-the-middle attack
Journal of Mathematical Cryptology, 2019 Over the past decade, the hybrid lattice-reduction and meet-in-the middle attack (called hybrid attack) has been used to evaluate the security of many lattice-based cryptographic schemes such as NTRU, NTRU Prime, BLISS and more.

Engineering Reports, Volume 8, Issue 4, April 2026.Smart meter (SM): Collect the data of users' electricity consumption periodically, and preprocess the noise reduction by using the Robust Local Weighted Regression algorithm, then encrypt the private data in it by Boneh‐Goh‐Nissim homomorphic encryption, and submit the encrypted private data to the fog node.

A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication
CAAI Transactions on Intelligence Technology, Volume 11, Issue 2, Page 349-366, April 2026.ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.
