{"publisher":"Springer","publist_id":"5005","abstract":[{"lang":"eng","text":"We introduce policy-based signatures (PBS), where a signer can only sign messages conforming to some authority-specified policy. 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."}],"language":[{"iso":"eng"}],"user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","doi":"10.1007/978-3-642-54631-0_30","scopus_import":1,"conference":{"end_date":"2014-05-28","name":"PKC: Public Key Crypography","start_date":"2014-05-26","location":"Buenos Aires, Argentina"},"citation":{"mla":"Bellare, Mihir, and Georg Fuchsbauer. “Policy-Based Signatures.” <i>Lecture Notes in Computer Science (Including Subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)</i>, edited by Hugo Krawczyk, vol. 8383, Springer, 2014, pp. 520–37, doi:<a href=\"https://doi.org/10.1007/978-3-642-54631-0_30\">10.1007/978-3-642-54631-0_30</a>.","ista":"Bellare M, Fuchsbauer G. 2014.
