    Castell Uroz, Ismael; Solé Pareta, Josep; Barlet Ros, Pere (2020-12)
    Article
    Open Access
    Digital society has developed to a point where it is nearly impossible for a user to know what it is happening in the background when using the Internet. To understand it, it is necessary to perform network measurements ...
  • (Position paper) Characterizing the behavior of small producers in smart grids: A data sanity analysis 

    Stefan, Maria; Gutiérrez López, José Manuel; Barlet Ros, Pere; Prieto Araujo, Eduardo; Gomis Bellmunt, Oriol; Olsen, Rasmus L. (Elsevier, 2020)
    Article
    Open Access
    Renewable energy production throughout low-voltage grids has gradually increased in electrical distribution systems, therefore introducing small energy producers - prosumers. This paradigm challenges the traditional ...
  • Bringing JSON signatures to ETSI AdES framework: Meet JAdES signatures 

    Cruellas Ibarz, Juan Carlos (Elsevier, 2020-08)
    Article
    Restricted access - publisher's policy
    This paper proposes a set of JSON signed and unsigned attributes which, if incorporated into a JSON signature, will convert it in a digital signature (JAdES) with identical capabilities (for instance, feasibility of ...
