A new method of choosing primitive elements for Brezing–Weng families of pairing-friendly elliptic curves

Journal of Mathematical Cryptology, 2015
In this paper we present a new method of choosing primitive elements for Brezing–Weng families of pairing-friendly elliptic curves with small rho-values, and we improve on previously known best rho-values of families [J.

Inner product functional encryption based on the UOV scheme

Journal of Mathematical Cryptology
We analyze the efficiency and security of the inner product functional encryption (IPFE) protocol introduced in 2021 by Debnath, Mesnager, Dey, and Kundu, specifically when instantiated with UOV.

New lattice attacks on DSA schemes

Journal of Mathematical Cryptology, 2016
We prove that a system of linear congruences of a particular form has at most a unique solution below a certain bound which can be computed efficiently.

On the Dimension of Algebraic-Geometric Trace Codes

Mathematics, 2016
We study trace codes induced from codes defined by an algebraic curve X. We determine conditions on X which admit a formula for the dimension of such a trace code.

A note on cohomology and algebraic geometric codes on the curves over rings

Annals of the West University of Timisoara: Mathematics and Computer Science
Let A be a local Artinian ring with residue field k(A). Let X be a curve over A and let be X′ = X ×spec A spec k(A) the fiber of X over k(A). Consider ℒ an invertible sheaf on X and ℒ ′ = ϕ*ℒ ∈ Pic(X′), where ϕ : X′ → X is the natural map.

A small serving of mash: (Quantum) algorithms for SPDH-Sign with small parameters

Journal of Mathematical Cryptology
We find an efficient method to solve the semidirect discrete logarithm problem (SDLP) over finite nonabelian groups of order p3{p}^{3} and exponent p2{p}^{2} for certain exponentially large parameters. This implies an attack on SPDH-Sign,Pronounced “SPUD-

Smaller public keys for MinRank-based schemes

Journal of Mathematical Cryptology
MinRank is an NP-complete problem in linear algebra whose characteristics make it attractive to build post-quantum cryptographic primitives. Several MinRank-based digital signature schemes have been proposed.
