      The Internet of Things (IoT) is on the rise. Today, various IoT platforms are already available, giving access to myriads of things. Initiatives such as BIG IoT are bringing those IoT platforms together in order to form ...
    • Privacy risk analysis in the IoT domain 

      Hernández Serrano, Juan; Muñoz Tapia, José Luis; León Abarca, Olga; Mikkelsen, Lars; Schwefel, Hans-Peter; Bröring, Arne (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Open Access
      Most IoT systems are using or exchanging user related information between system components. This means that privacy is a key factor in these systems. Privacy, both in terms of not allowing unauthorized access to information, ...
    • Providing k-anonymity and revocation in ubiquitous VANETs 

      Caballero Gil, Cándido; Molina Gil, Jezabel; Hernández Serrano, Juan; León Abarca, Olga; Soriano Ibáñez, Miguel (Elsevier, 2016-01)
      Article
      Open Access
      Abstract Vehicular ad hoc networks (VANETs) is considered a milestone in improving the safety and efficiency in transportation. Nevertheless, when information from the vehicular communications is combined with data from ...
