The main requirements are unforgeability and privacy, the latter meaning that signatures not reveal the policy. PBS offers value along two fronts: (1) On the practical side, they allow a corporation to control what messages its employees can sign under the corporate key. (2) On the theoretical side, they unify existing work, capturing other forms of signatures as special cases or allowing them to be easily built. Our work focuses on definitions of PBS, proofs that this challenging primitive is realizable for arbitrary policies, efficient constructions for specific policies, and a few representative applications.","lang":"eng"}],"main_file_link":[{"url":"https://eprint.iacr.org/2013/413","open_access":"1"}],"department":[{"_id":"KrPi"}],"date_created":"2018-12-11T11:55:24Z","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","oa_version":"Submitted Version","oa":1,"scopus_import":1,"publisher":"Springer","status":"public","quality_controlled":"1","title":"Policy-based signatures","alternative_title":["LNCS"]}
