Lattice-based extended withdrawability

Ramses Fernandez-Valencia

We extend the extended withdrawable signatures of Liu, Susilo and Baek to lattice-based constructions built on the Fiat-Shamir with aborts paradigm. Departing from an earlier draft…

Withdrawability in Fiat-Shamir with aborts constructions

Ramses Fernandez-Valencia

This article presents an extension of the work performed by Liu, Baek and Susilo on withdrawable signatures to the Fiat-Shamir with aborts paradigm. We introduce an abstract constr…

Verifiable encodings in multigroup fully homomorphic encryption

Ramsès Fernàndez-València

This article presents the application of homomorphic authenticators, replication encodings to be precise, to multigroup fully homomorphic encryption schemes. Following the works of…

Undeniable signatures based on isogenies of supersingular hyperelliptic curves

Ramsès Fernàndez-València

We present a proposal for an undeniable signature scheme based in supersingular hyperelliptic curves of genus 2.

Genus 2 Supersingular Isogeny Oblivious Transfer

Ramsès Fernàndez-València

We present an oblivious transfer scheme that extends the proposal made by Barreto, Oliveira and Benits, based in isogenies supersingular elliptic curves, to the setting of principa…

Hochschild homology and cohomology for involutive -algebras

Ramses Fernandez-Valencia

We present a study of the homological algebra of bimodules over -algebras endowed with an involution. Furthermore we introduce a derived description of Hochschild homolog…
