Improved Bounds on Security Reductions for Discrete Log Based Signatures
Despite considerable research efforts, no efficient reduction from the discrete log problem to forging a discrete log based signature (e.g. Schnorr) is currently known. In fact, ne...

Generic Security-Amplifying Methods of Ordinary Digital Signatures
We describe two new paradigms on how to obtain ordinary signatures that are secure against existential forgery under adaptively chosen message attacks (fully-secure, in short), fro...

Undeniable Signatures
Abstract. In this paper, we provide a new approach to study undeniable signatures by translating secure digital signatures to secure undeniable signatures so that the existing algo...

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...
