Efficient polynomial delegation under standard assumptions
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Conference lecture
Restricted access - publisher's policyIn this paper we present a new scheme for verifiable delegation of polynomials in a cloud computing scenario. The security of our scheme is based on a standard assumption, the subgroup membership one. Furthermore, the ... -
El diámetro de ciertos digrafos circulantes de triple paso
(Universidad de Barcelona, Departamento de Estadística Matemática;Universidad Politécnica de Barcelona, Escuela Técnica Superior de Arquitectura, Departamento de Matemáticas y Estadística, 1986)
Article
Open AccessThis paper studies some diameter-related properties of the $3$-step circulant digraphs with set of vertices $V=Z_N$ and steps $(\pm a,b)$. More precisely, it concentrates upon maximizing their order $N$ for any fixed ... -

Lattice-Based proof of a shuffle
(2019)
Conference report
Open AccessIn this paper we present the first fully post-quantum proof of a shuffle for RLWE encryption schemes. Shuffles are commonly used to construct mixing networks (mix-nets), a key element to ensure anonymity in many applications ... -
Matrix computational assumptions in multilinear groups
(2015-04-20)
Research report
Open AccessWe put forward a new family of computational assumptions, the Kernel Matrix Di e- Hellman Assumption. Given some matrix A sampled from some distribution D `;k , the kernel as- sumption says that it is hard to nd \in the exponent -

RLWE-Based Zero-Knowledge Proofs for Linear and Multiplicative Relations
(Springer International Publishing, 2019)
Conference report
Restricted access - publisher's policyWe present efficient Zero-Knowledge Proofs of Knowledge (ZKPoK) for linear and multiplicative relations among secret messages hidden as Ring Learning With Errors (RLWE) samples. Messages are polynomials in $\mathbb{Z}_q[ ... -

Vote validatability in Mix-Net-based eVoting
(2015)
Article
Open AccessOne way to build secure electronic voting systems is to use Mix-Nets, which break any correlation between voters and their votes. One of the characteristics of Mix-Net-based eVoting is that ballots are usually decrypted ...
