On the leakage-resilient key exchange

Journal of Mathematical Cryptology, 2017
Typically, secure channels are constructed from an authenticated key exchange (AKE) protocol, which authenticates the communicating parties based on long-term public keys and establishes secret session keys.

Pl\"ucker Embedding of Cyclic Orbit Codes [PDF]

, 2012
Cyclic orbit codes are a family of constant dimension codes used for random network coding. We investigate the Pl\"ucker embedding of these codes and show how to efficiently compute the Grassmann coordinates of the code words.Comment: to appear in ...

On linear codes with random multiplier vectors and the maximum trace dimension property

Journal of Mathematical Cryptology
Let CC be a linear code of length nn and dimension kk over the finite field Fqm{{\mathbb{F}}}_{{q}^{m}}. The trace code Tr(C){\rm{Tr}}\left(C) is a linear code of the same length nn over the subfield Fq{{\mathbb{F}}}_{q}.

Every Binary Self-Dual Code Arises From Hilbert Symbols

, 2012
In this paper we construct binary self-dual codes using the \'etale cohomology of $\mathbb{Z}/2$ on the spectra of rings of $S$-integers of global fields.

Application of Mordell–Weil lattices with large kissing numbers to acceleration of multiscalar multiplication on elliptic curves

Journal of Mathematical Cryptology
This article aims to speed up (the precomputation stage of) multiscalar multiplication (MSM) on ordinary elliptic curves of j-invariant 0 with respect to specific “independent” (also known as “basis”) points.

DAGS: Key encapsulation using dyadic GS codes

Journal of Mathematical Cryptology, 2018
Code-based cryptography is one of the main areas of interest for NIST’s Post-Quantum Cryptography Standardization call. In this paper, we introduce DAGS, a Key Encapsulation Mechanism (KEM) based on quasi-dyadic generalized Srivastava codes.

One- and Two-Point Codes over Kummer Extensions

, 2016
We compute the Weierstrass semigroup at one totally ramified place for Kummer extensions defined by $y^m=f(x)^{\lambda}$ where $f(x)$ is a separable polynomial over $\mathbb{F}_q$.

Predicate signatures from pair encodings via dual system proof technique

Journal of Mathematical Cryptology, 2019
Recently, Attrapadung (Eurocrypt 2014) proposed a generic framework for fully (adaptively) secure predicate encryption (PE) based on a new primitive, called pair encodings.

Some bounds for the relative generalized Hamming weights of some evaluation codes

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
In this paper we find some bounds for the relative generalized Hamming weights of some codes parameterized by a set of monomials of the same degree.

Further Results of the Cryptographic Properties on the Butterfly Structures

, 2016
Recently, a new structure called butterfly introduced by Perrin et at. is attractive for that it has very good cryptographic properties: the differential uniformity is at most equal to 4 and algebraic degree is also very high when exponent $e=3$.
