摘要
We present a formal model for domain pseudonymous signatures - in particular providing a simple and strong concept and comprehensive formalization of unlinkability, which is the key property of domain pseudonymous signatures. Following the approach deployed for German personal identity cards, we consider domains that have to be registered and require a particular form of domain specifications. We introduce and formalize the deanonymization procedures that have to be implemented as one of the crucial functionalities in many application areas of domain signatures. Finally, we present two constructions that correspond to this model.
