    Conference report
    Restricted access - publisher's policy
    Microaggregation is one of the most employed microdata protection methods. The idea is to build clusters of at least k original records, and then replace them with the centroid of the cluster. When the number of attributes ...
  • Attribute-based authorization for structured Peer-to-Peer (P2P) networks 

    Suarez Touzeda, Diego; Sierra Camara, Jose Maria; Zeadally, Sherali; Soriano Ibáñez, Miguel (Elsevier, 2015-11-01)
    Article
    Restricted access - publisher's policy
    We present the deficiencies of traditional identity-based authorization models in structured Peer-to-Peer (P2P) networks where users' Public Key Certificates (PKCs) represent two roles, authentication and authorization, ...
  • Attribute-based versions of Schnorr and ElGamal 

    Herranz Sotoca, Javier (2016-01)
    Article
    Open Access
    We design in this paper the first attribute-based cryptosystems that work in the classical discrete logarithm, pairing-free, setting. The attribute-based signature scheme can be seen as an extension of Schnorr signatures, ...
  • Attributed graph matching for image-features association using SIFT descriptors 

    Sanromà Güell, Gerard; Alquézar Mancho, René; Serratosa Casanelles, Francesc (Springer, 2010)
    Conference report
    Open Access
    Image-features matching based on SIFT descriptors is subject to the misplacement of certain matches due to the local nature of the SIFT representations. Some well-known outlier rejectors aim to remove those misplaced matches ...
  • Attribution of extreme weather and climate events overestimated by unreliable climate simulations 

    Bellprat, Omar; Doblas-Reyes, Francisco (American Geophysical Union (AGU), 2016-03-16)
    Article
    Open Access
    Event attribution aims to estimate the role of an external driver after the occurrence of an extreme weather and climate event by comparing the probability that the event occurs in two counterfactual worlds. These ...
