NTRU-Like Random Congruential Public-Key Cryptosystem for Wireless Sensor Networks [PDF]
Sensors, 2020 Wireless sensor networks (WSNs) are the core of the Internet of Things and require cryptographic protection. Cryptographic methods for WSN should be fast and consume low power as these networks rely on battery-powered devices and microcontrollers.

Practical NTRU Signcryption in the Standard Model [PDF]
Entropy, 2023 Based on the NTRU trapdoor used in NIST’s Falcon, a signcryption scheme following the sign-then-encrypt paradigm is constructed. The existing partitioning technique based on Waters hash over the lattice can not complete the security reduction in the ...

A Post-Quantum Secure RFID Authentication Protocol Based on NTRU Encryption Algorithm [PDF]
SensorsAs a non-contact identification technology, RFID (Radio Frequency Identification) is widely used in various Internet of Things applications. However, RFID systems are highly vulnerable to diverse attacks due to the openness of communication links between

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.

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

, 2010 In this paper NTRUEncrypt is implemented for the first time on a GPU using the CUDA platform. As is shown, this operation lends itself perfectly for parallelization and performs extremely well compared to similar security levels for ECC and RSA giving speedups of around three to five orders of magnitude.

Characterizing overstretched NTRU attacks [PDF]
Journal of Mathematical Cryptology, 2020 Abstract Overstretched 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.

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.

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 ...
