  1. 1. Be More and be Merry: Enhancing Data and User Authentication in Collaborative Settings

    Författare :Elena Pagnin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Homomorphic Signatures; Server-Aided Verification; Distance-Bounding Authentication Protocols; Verifiable Com- putation; Biometric Authentication.;

    Sammanfattning : Cryptography is the science and art of keeping information secret to un-intended parties. But, how can we determine who is an intended party and who is not? Authentication is the branch of cryptography that aims at confirming the source of data or at proving the identity of a person. This Ph.D. LÄS MER
