— A self-healing key distribution scheme enables a large group of users (sensor nodes) to establish a session key dynamically over an unreliable, or lossy wireless network. The m...
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...
—The group signature based security scheme is a promising approach to provision privacy in vehicular ad hoc networks (VANETs). In this paper, we propose a novel distributed key m...
In this work, we propose a new generalization of the notion of group signatures, that allows signers to cover the entire spectrum from complete disclosure to complete anonymity. Pr...
Abstract. One of the central lines of cryptographic research is identifying the weakest assumptions required for the construction of secure primitives. In the context of group sign...
