They can efficiently prove that their credentials satisfy complex (access) policies in a privacy-preserving way. This implements anonymous access control with complex policies.\r\n\r\nFurthermore, CLARC is the first ACS that is combined with an anonymous reputation system where users can anonymously rate services. A user who gets access to a service via a credential, also anonymously receives a review token to rate the service. If a user creates more than a single rating, this can be detected by anyone, preventing users from spamming ratings to sway public opinion.\r\n\r\nTo evaluate feasibility of our construction, we present an open-source prototype implementation.","lang":"eng"}],"type":"conference","date_updated":"2022-01-06T06:59:07Z","conference":{"name":"ARES 2018 - SECPID","end_date":"2018-08-30","start_date":"2018-08-27","location":"Hamburg, Germany"},"publication":"Proceedings of the 13th International Conference on Availability, Reliability and Security - ARES '18","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://eprint.iacr.org/2018/835"}],"title":"Fully-Featured Anonymous Credentials with Reputation System","_id":"3265","department":[{"_id":"64"}],"publication_identifier":{"isbn":["978-1-4503-6448-5"]},"user_id":"25078","citation":{"chicago":"Bemmann, Kai, Johannes Blömer, Jan Bobolz, Henrik Bröcher, Denis Pascal Diemert, Fabian Eidens, Lukas Eilers, et al. “Fully-Featured Anonymous Credentials with Reputation System.” In <i>Proceedings of the 13th International Conference on Availability, Reliability and Security - ARES ’18</i>.
