A CellBE-based HPC application for the analysis of vulnerabilities in cryptographic hash functions
(2010)
Text en actes de congrés
Accés restringit per política de l'editorialAfter some recent breaks presented in the technical literature, it has become of paramount importance to gain a deeper understanding of the robustness and weaknesses of cryptographic hash functions. In particular, in the ... -
A construction of traceability set systems with polynomial tracing algorithm
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Text en actes de congrés
Accés obertA family F of w-subsets of a finite set X is called a set system with the identifiable parent property if for any w-subset contained in the union of some t sets, called traitors, of F at least one of these sets can be ... -

A new character-level encryption algorithm: how to implement cryptography in an ICT classroom
(OmniaScience, 2019-09)
Article
Accés obertIt is evident that the society in which we live will demand more and more qualified and specialized positions in the different branches of engineering. Now we are in a highly digitized world in which information is ... -
A new class of codes for fingerprinting schemes
(Springer, 2005)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper we discuss the problem of collusion secure fingerprinting. In the first part of our contribution we prove the existence of equidistant codes that can be used as fingerprinting codes. Then we show that by ... -
A new countermeasure against side-channel attacks based on hardware-software co-design
(2016-09-01)
Article
Accés obertThis paper aims at presenting a new countermeasure against Side-Channel Analysis (SCA) attacks, whose implementation is based on a hardware-software co-design. The hardware architecture consists of a microprocessor, which ... -
A note about the traceability properties of linear codes
(Springer, 2007)
Text en actes de congrés
Accés restringit per política de l'editorialWe characterize the traceability properties of linear codes. It is well known that any code of length n and minimum distance d is a c-TA code if c 2¿<¿n/(n¿-¿d). In this paper, we show that a less restrictive condition can ... -
A probabilistic concept of accessibility for access structures
(2008-06-13)
Report de recerca
Accés obertIn this paper we introduce the concept of weighted accessibility for access structures. In some sense, it represents a measure of how difficult or how easy is to recover the secret. We give also a numerical measure of ... -

Treball Final de Grau
Accés obert
Realitzat a/amb: Massachusetts Institute of Technology / Massachusetts Institute of TechnologyLes proves de coneixement zero són una eina criptogràfica altament prometedora que permet demostrar que un predicat és correcte sense revelar informació addicional sobre aquest. Aquestes tipus de proves són útils en ... -
Advanced cryptographic techniques for building verifiable and transparent electronic voting protocols
(Universitat Politècnica de Catalunya, 2017-07-21)
Tesi
Accés obertElectronic voting presents many challenges due to its multiple security requirements. Some of the challenges are related to guaranteeing voters' privacy and system's transparency, which are hard to satisfy simultaneously. ... -
