A New Trick for Polynomial Multiplication

Transactions on Cryptographic Hardware and Embedded Systems
In this paper we present a novel transformation strategy for polynomial multiplications and apply it to NTRU Prime, specifically the parameter sets sntrup761 and ntrulpr761 working in the ring Z4591[x]/⟨x761−x−1⟩.

Algorithms on Ideal over Complex Multiplication order [PDF]

, 2016
We show in this paper that the Gentry-Szydlo algorithm for cyclotomic orders, previously revisited by Lenstra-Silverberg, can be extended to complex-multiplication (CM) orders, and even to a more general structure.

Provably weak instances of ring-LWE revisited [PDF]

, 2016
In CRYPTO 2015, Elias, Lauter, Ozman and Stange described an attack on the non-dual decision version of the ring learning with errors problem (RLWE) for two special families of defining polynomials, whose construction depends on the modulus q that is ...

Multikey Fully Homomorphic Encryption: Removing Noise Flooding in Distributed Decryption via the Smudging Lemma on Discrete Gaussian Distribution

IET Information Security, Volume 2025, Issue 1, 2025.
The current multikey fully homomorphic encryption (MKFHE) needs to add exponential noise in the distributed decryption phase to ensure the simulatability of partial decryption. Such a large noise causes the ciphertext modulus of the scheme to increase exponentially compared to the single‐key fully homomorphic encryption (FHE), further reducing the ...

Optimized Design and Implementation of CRYSTALS‐KYBER Based on MLWE

Security and Communication Networks, Volume 2025, Issue 1, 2025.
CRYSTALS‐KYBER is a postquantum key exchange mechanism based on the MLWE problem. At present, it is a major challenge to realize CRYSTALS‐KYBER with high‐performance and low‐resource consumption on the FPGA platform. The design proposed in this paper aims at the high efficiency implementation of CRYSTALS‐KYBER based on the MLWE scheme.
