Obtaining the soliton solutions of local M-fractional magneto-electro-elastic media
Heliyon, 2023 In this research paper, the generalized projective Riccati equations method (GPREM) is applied successfully to procure the soliton solutions of the local M-fractional longitudinal wave equation (LWE) arising in mathematical physics with dispersion caused

Additively Homomorphic Ring-LWE Masking [PDF]
, 2016 In this paper, we present a new masking scheme for ring-LWE decryption. Our scheme exploits the additively-homomorphic property of the existing ring-LWE encryption schemes and computes an additive-mask as an encryption of a random message. Our solution differs in several aspects from the recent masked ring-LWE implementation by Reparaz et al. presented

Reduction From Module-SIS to Ring-SIS Under Norm Constraint of Ring-SIS
IEEE Access, 2020 Lattice-based cryptographic scheme is constructed based on hard problems on a lattice such as the short integer solution (SIS) problem and the learning with error (LWE).

Estimation of the hardness of the learning with errors problem with a restricted number of samples
Journal of Mathematical Cryptology, 2019 The Learning With Errors (LWE) problem is one of the most important hardness assumptions lattice-based constructions base their security on. In 2015, Albrecht, Player and Scott presented the software tool LWE-Estimator to estimate the hardness of ...

Ad Hoc Multi-Input Functional Encryption [PDF]
, 2019 Consider sources that supply sensitive data to an aggregator. Standard encryption only hides the data from eavesdroppers, but using specialized encryption one can hope to hide the data (to the extent possible) from the aggregator itself.

Ring-LWE in Polynomial Rings [PDF]
, 2012 The Ring-LWE problem, introduced by Lyubashevsky, Peikert, and Regev (Eurocrypt 2010), has been steadily finding many uses in numerous cryptographic applications. Still, the Ring-LWE problem defined in [LPR10] involves the fractional ideal R ∨, the dual of the ring R , which is the source of many theoretical and implementation technicalities. Until now,

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.

Security considerations for Galois non-dual RLWE families [PDF]
, 2017 We explore further the hardness of the non-dual discrete variant of the Ring-LWE problem for various number rings, give improved attacks for certain rings satisfying some additional assumptions, construct a new family of vulnerable Galois number fields ...

Quantum-secure message authentication via blind-unforgeability [PDF]
, 2020 Formulating and designing unforgeable authentication of classical messages in the presence of quantum adversaries has been a challenge, as the familiar classical notions of unforgeability do not directly translate into meaningful notions in the quantum ...

A Toolkit for Ring-LWE Cryptography [PDF]
, 2013 Recent advances in lattice cryptography, mainly stemming from the development of ring-based primitives such as ring-LWE, have made it possible to design cryptographic schemes whose efficiency is competitive with that of more traditional number-theoretic ones, along with entirely new applications like fully homomorphic encryption.
