Abstract

An anonymous delegation system enables individuals to retrieve rights and to delegate different subparts of these rights to different entities. The delegation procedure is anonymous, such that no collusion of entities can track an individual’s delegation behavior. On the other hand, it is ensured that a user cannot abuse her delegation capabilities. This paper introduces a general delegation model and presents an implementation. Our implementation is based on credential systems and provides both anonymity for the individual and security for the organizations.
