Electronic 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. ...

Aquest projecte es planteja com a un exercici per part de l'autor en aprofundir en el coneixement de les eines existents que s'utilitzen en l'àmbit de generar prediccions a partir de dades, concretament en dades en forma ...

[ANGLÈS] The purpose of this project is to review the current state of cryptographic systems, focusing in signatures schemes based on elliptic curves (such as Blind Signature, Aggregate Signature or Multisignature) and to ...

This 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 ...

We 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 ...

Recommendation 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 ...

This project has studied and analized an attack by injection of errors against the AES encryption scheme currently existing in literature. The AES symmetric cryptosystem is perhaps the most widely used today. The idea of ...

This final degree project will try to explain the blockchain technology, its related concepts and analyze a few cryptocurrencies that use it. First, we?ll do a state-of-art of their economic situation, just as an analysis ...
