We give a new framework for obtaining signatures with a tight security reduction from standard hardness assumptions. Concretely, we show that any Chameleon Hash function can be transformed into a (b...
In this paper, we propose the first identity-based chameleon hash scheme without key exposure, which gives a positive answer for the open problem introduced by Ateniese and de Medeiros in 2004.
Chameleon signatures are non-interactive signatures based on a hash-and-sign paradigm, and similar in efficiency to regular signatures. The distinguishing characteristic of chameleon signatures is t...
