We present a generic, efficient and iterative algorithm for interactively clustering classes of images and videos. The approach moves away from the use of large hand labelled tra...
The Fiat-Shamir (FS) transform is a popular tool to produce particularly efficient digital signature schemes out of identification protocols. It is known that the resulting signat...
Abstract--We consider the use of threshold signatures in adhoc and dynamic groups such as MANETs ("mobile ad-hoc networks"). We first show that known threshold RSA signat...

More and more services provided by Internet pose a problem of privacy and anonymity. One cryptographic tool that could be used for solving this problem is the group signature [1, 5...
Task-specific groups are often formed in an ad-hoc manner within big structures, like companies. Take the following typical scenario: A high rank manager decides that a task force...
