Efficient Authentication for Reactive Routing Protocols
Ad hoc networks are dynamic networks formed "on the fly" by a set of nodes. Achieving secure routing in such networks is a big challenge. Asymmetric signature schemes pr...

Synchronized aggregate signatures: new definitions, constructions and applications
An aggregate signature scheme is a digital signature scheme where anyone given n signatures on n messages from n users can aggregate all these signatures into a single short signa...

The Fiat-Shamir Transform for Group and Ring Signature Schemes
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...

The Physically Observable Security of Signature Schemes
In recent years much research has been devoted to producing formal models of security for cryptographic primitives and to designing schemes that can be proved secure in such models...

Short and Stateless Signatures from the RSA Assumption
We present the first signature scheme which is “short”, stateless and secure under the RSA assumption in the standard model. Prior short, standard model signatures in the RSA...
