Comparison Between Algebraic Cryptanalysis on DES and NTRU
InPrime, 2023 Algebraic cryptanalysis is a cryptanalysis method that aims to exploit the algebraic structure of an encryption algorithm to obtain the secret key. Algebraic cryptanalysis becomes interesting because it uses a small amount of known plaintext, which in ...

Lattice Attacks on NTRU Revisited
IEEE Access, 2021 NTRU cryptosystem was proposed by J. Hoffstein, J.Pipher and J.H. Silverman in 1996, whose security is related to the hardness of finding sufficient short vectors in NTRU lattice with dimension $2N$ .

Security Analysis of Hybrid Attack for NTRU-Class Encryption Schemes
IEEE Access, 2023 One of the significant post-quantum cryptographic candidates is the NTRU public key cryptosystem. It operates on polynomial rings, where the parameter largely determines the security of the system.

NTRU-type fully homomorphic encryption scheme without key switching
网络与信息安全学报, 2017 In order to construct a fully homomorphic encryption scheme based on NTRU cryptosystem from ring learning with errors, noise growth and homomorphic property in the NTRU cryptosystem were analyzed. The con-cept of zero homomorphic encryption was introdced

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.

Characterizing overstretched NTRU attacks [PDF]
Journal of Mathematical Cryptology, 2020 AbstractOverstretched NTRU is a variant of NTRU with a large modulus. Recent lattice subfield and subring attacks have broken suggested parameters for several schemes. There are a number of conflicting claims in the literature over which attack has the best performance. These claims are typically based on experiments more than analysis.

Flattening NTRU for Evaluation Key Free Homomorphic Encryption
Journal of Mathematical Cryptology, 2020 We propose a new FHE scheme F-NTRU that adopts the flattening technique proposed in GSW to derive an NTRU based scheme that (similar to GSW) does not require evaluation keys or key switching.

A New Attack on NTRU Public Key Cryptosystem Depend on Using Public Key and Public Information [PDF]
Engineering and Technology Journal, 2010 This paper proposed a new method to attack the NTRU cryptosystem [Hof00a,Hof98b]. It tried to exploit the public information about the parameters of NTRUcryptosystem and using the public key, to recover the private keys without delvingin the detail of ...

Quantum algorithms for attacking hardness assumptions in classical and post‐quantum cryptography
IET Information Security, Volume 17, Issue 2, Page 171-209, March 2023., 2023 Abstract In this survey, the authors review the main quantum algorithms for solving the computational problems that serve as hardness assumptions for cryptosystem. To this end, the authors consider both the currently most widely used classically secure cryptosystems, and the most promising candidates for post‐quantum secure cryptosystems.
