  text: "We present CLARC (Cryptographic Library for Anonymous Reputation and Credentials),
    an anonymous credentials system (ACS) combined with an anonymous reputation system.\r\n\r\nUsing
    CLARC, users can receive attribute-based credentials from issuers. 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."

  text: Group signatures, introduced by Chaum and van Heyst [15], are an important
    primitive in cryptography. In group signature schemes every group member can anonymously
    sign messages on behalf of the group. In case of disputes a dedicated opening
    manager is able to trace signatures - he can extract the identity of the producer
    of a given signature. A formal model for static group signatures schemes and their
    security is defined by Bellare, Micciancio, and Warinschi [4], the case of dynamic
    groups is considered by Bellare, Shi, and Zhang [5]. Both models define group
    signature schemes with a single opening manager. The main difference between these
    models is that the number of group members in static schemes is fixed, while in
    dynamic schemes group members can join the group over time.

  text: Reputation systems are used to compute and publish reputation scores for services
    or products. We consider reputation systems where users are allowed to rate products
    that they purchased previously. To obtain trustworthy reputations, they are allowed
    to rate these products only once. As long as users rate products once, they stay
    anonymous. Everybody is able to detect users deviating from the rate-products-only-once
    policy and the anonymity of such dishonest users can be revoked by a system manager.
    In this paper we present formal models for such reputation systems and their security.
    Based on group signatures presented by Boneh, Boyen, and Shacham we design an
    efficient reputation system that meets all our requirements.
