    • Equivalences and black-box separations of Matrix Diffie-Hellman problems 

      Villar Santos, Jorge Luis (2017-02)
      Article
      Accés obert
      In this paper we provide new algebraic tools to study the relationship between different Matrix Diffie-Hellman (MDDH) Problems, which are recently introduced as a natural generalization of the so-called Linear Problem. ...

    • Matrix computational assumptions in multilinear groups 

      Morillo Bosch, M. Paz; Ràfols Salvador, Carla; Villar Santos, Jorge Luis (2015-04-20)
      Report de recerca
      Accés obert
      We put forward a new family of computational assumptions, the Kernel Matrix Di e- Hellman Assumption. Given some matrix A sampled from some distribution D `;k , the kernel as- sumption says that it is hard to nd \in the exponent

    • Public verifiability from pairings in secret sharing schemes 

      Heidarvand, Somayed; Villar Santos, Jorge Luis (2009)
      Article
      Accés restringit per política de l'editorial
      In this paper we propose a new publicly verifiable secret sharing scheme using pairings with close relations to Shoenmakers’ scheme. This scheme is efficient, multiplicatively homomorphic and with unconditional verifiability ...
    • The Kernel Matrix Diffie-Hellman Assumption 

      Morillo Bosch, M. Paz; Ràfols Salvador, Carla; Villar Santos, Jorge Luis (2016-12)
      Article
      Accés obert
      We put forward a new family of computational assumptions, the Kernel Matrix Diffie-Hellman Assumption. Given some matrix A sampled from some distribution D, the kernel assumption says that it is hard to find “in the exponent” ...
