If the entities which take part in a proxy signature scheme are formed by sets of participants, then we refer to it as a fully distributed proxy signature scheme.
In this work, we extend the security definitions introduced by Boldyreva et al. to the scenario of fully distributed proxy signature schemes, and we propose a specific scheme which is secure in this new model.
