(2010)
Conference report
Restricted access - publisher's policyAfter 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 new character-level encryption algorithm: how to implement cryptography in an ICT classroom
(OmniaScience, 2019-09)
Article
Open AccessIt 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)
Conference report
Restricted access - publisher's policyIn 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
Open AccessThis 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)
Conference report
Restricted access - publisher's policyWe 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 privacy-protecting architecture for collaborative filtering via forgery and suppression of ratings
(Springer, 2011)
Conference report
Restricted access - publisher's policyRecommendation systems are information-filtering systems that help users deal with information overload. Unfortunately, current recommendation systems prompt serious privacy concerns. In this work, we propose an architecture ... -

Advanced cryptographic techniques for building verifiable and transparent electronic voting protocols
(Universitat Politècnica de Catalunya, 2017-07-21)
Doctoral thesis
Open AccessElectronic 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. ... -
An experimental realization of a chaos-based secure communication using arduino microcontrollers
(2015-08-27)
Article
Open AccessSecurity and secrecy are some of the important concerns in the communications world. In the last years, several encryption techniques have been proposed in order to improve the secrecy of the information transmitted. ... -
