On the Random-Oracle Methodology as Applied to Length-Restricted Signature Schemes
In earlier work, we described a “pathological” example of a signature scheme that is secure in the Random Oracle Model, but for which no secure implementation exists. For that...

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...
