  • Ataque diferencial mediante inyección de un error en AES-128 

    Trayno, Vladlena (Universitat Politècnica de Catalunya, 2016)
    Master thesis (pre-Bologna period)
    Open Access
    This project has studied and analized an attack by injection of errors against the AES encryption scheme currently existing in literature. The AES symmetric cryptosystem is perhaps the most widely used today. The idea of ...
  • Contributions to secret sharing and other distributed cryptosystems 

    Ruiz Rodríguez, Alexandre (Universitat Politècnica de Catalunya, 2013-07-22)
    Doctoral thesis
    Open Access
    The present thesis deals with primitives related to the eld of distributed cryptography. First, we study signcryption schemes, which provide at the same time the functionalities of encryption and signature, where the ...
  • Some Digital Signature Schemes with Collective Signers 

    Herranz Sotoca, Javier (Universitat Politècnica de Catalunya, 2005-04-15)
    Doctoral thesis
    Open Access
    Digital signatures are one of the most important consequences of the appearance of public key cryptography, in 1976. These schemes provide authentication, integrity and non-repudiation to digital communications. <br/>Some ...
