• 'Ad-hoc' threshold broadcast encryption with shorter ciphertexts

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

  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 plaintext ...
• Relations between semantic security and anonymity in identity-based encryption

  Herranz, Javier; Laguillaumie, Fabien; Ràfols, Carla (Elsevier, 2011)

• Attribute-based encryption schemes with constant-size ciphertexts

  Attrapadung, Nuttapong; Herranz, Javier; Laguillaumie, Fabien; Libert, Benoît; De Panafieu, Elie; Ràfols, Carla (Elsevier, 2012)

  Attribute-based encryption (ABE), as introduced by Sahai and Waters, allows for fine- grained access control on encrypted data. In its key-policy flavor (the dual ciphertext-policy scenario proceeds the other way around), ...
• An intelligent interface for drum pattern variation and comparative evaluation of algorithms

  Vogl, Richard; Leimeister, Matthias; Nuanáin, Carthach Ó; Hlatky, Michael; Jordà Puig, Sergi; Knees, Peter (Audio Engineering Society, 2016)

  Drum tracks of electronic dance music pieces are a central and style-defining element. Yet,creating them can be a cumbersome task, mostly due to lack of appropriate tools and inputdevices. In this work we use a UI prototype ...
• Early positivity signals changes in an abstract linguistic pattern

  Monte Ordoño, Julia, 1989-; Toro Soto, Juan Manuel, 1976- (Public Library of Science (PLoS), 2017)

  The extraction of abstract structures from speech (or from gestures in the case of sign languages) has been claimed to be a fundamental mechanism for language acquisition. In the present study we registered the neural ...
• Early neural responses underlie advantages for consonance over dissonance

  Crespo Bojorque, Paola, 1985-; Monte Ordoño, Julia, 1989-; Toro Soto, Juan Manuel, 1976- (Elsevier, 2018)

  Consonant musical intervals tend to be more readily processed than dissonant intervals. In the present study, we explore the neural basis for this difference by registering how the brain responds after changes in consonance ...
• Learning a new selection rule in visual and frontal cortex

  van der Togt, Chris; Stănişor, Liviu; Pooresmaeili, Arezoo; Albantakis, Larissa; Deco, Gustavo; Roelfsema, Pieter R. (Oxford University Press, 2016)

  How do you make a decision if you do not know the rules of the game? Models of sensory decision-making suggest that choices are slow if evidence is weak, but they may only apply if the subject knows the task rules. Here, ...
• FUBImethod: strategies to engage children in the co-design of Full-Body interactive experiences
