We consider the problem of secure identification: user U proves to server S that he knows an agreed (possibly low-entropy) password w, while giving away as little information on w ...
Abstract. The use of biometrics, and fingerprint recognition in particular, for cardholder authentication in smartcard systems is growing in popularity, and such systems are the f...
Abstract: Hash functions are used in many cryptographic constructions under various assumptions, and the practical impact of collision attacks is often unclear. In this paper, we s...
Broadcast authentication is an important application in sensor networks. Public Key Cryptography (PKC) is desirable for this application, but due to the resource constraints on se...
Serge Vaudenay [20] introduced a notion of Message Authentication (MA) protocols in the Short Authenticated String (SAS) model. A SAS-MA protocol authenticates arbitrarily long mes...
