• CCA2-secure threshold broadcast encryption with shorter ciphertexts

  Daza, Vanesa; Herranz, Javier; Morillo, Paz; Ràfols, Carla (Springer, 2007)

  In a threshold broadcast encryption scheme, a sender chooses (ad-hoc) a set of n receivers and a threshold t, and then encrypts a message by using the public keys of all the receivers, in such a way that the original ...
• On dynamic distribution of private keys over MANETs

  Daza, Vanesa; Morillo, Paz; Ràfols, Carla (Elsevier, 2007)

  Identity-Based cryptography has been proposed in mobile ad-hoc networks (MANETs) to provide security. However, the figure of the Private Key Generator (PKG) is not adequate in the MANET setting, since it may not be ...
• 'Ad-hoc' threshold broadcast encryption with shorter ciphertexts

  Daza, Vanesa; Herranz, Javier; Morillo, Paz; Ràfols, Carla (Elsevier, 2008)
