In 2002, Micali and Rivest raised an open problem as to whether directed transitive signatures exist or not. In 2003, Hohenberger formalized the necessary mathematical criteria for...
—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...
We describe a short signature scheme that is strongly existentially unforgeable under an adaptive chosen message attack in the standard security model. Our construction works in g...
The Pintsov-Vanstone signature scheme with partial message recovery (PVSSR) is a variant of the Schnorr and Nyberg-Rueppel signature schemes. It produces very short signatures on ...
Abstract. Courtois, Finiasz and Sendrier proposed in 2001 a practical code-based signature scheme. We give a rigorous security analysis of a modified version of this scheme in the...
