    • Exploiting isogeny cordillera structure to obtain cryptographically good elliptic curves 

      Miret, Josep M. (Josep Maria); Tomàs, Rosana; Valls Marsal, Magda; Sadornil Renedo, Daniel; Tena Ayuso, Juan (Australian Computer Society Inc, 2008)
      The security of most elliptic curve cryptosystems is based on the intractability of the Elliptic Curve Discrete Logarithm Problem (ECDLP). Such a problem turns out to be computationally unfeasible when elliptic curves ...
    • Securing Databases by using Diagonal-based Order Preserving Symmetric Encryption 

      Martínez Rodríguez, Santi; Miret, Josep M. (Josep Maria); Valls Marsal, Magda; Tomàs, Rosana (Natural Sciences Publishing, 2014)
      The amount of information stored in databases is constantly increasing. Databases contain multiple records, each of them divided in several data fields. And some of these fields may contain sensitive information, so there ...
