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…
