In recent years, electronic identification (eID) has become widespread, and this eID is used to access buildings and applied to the use of Web services. However, as a problem of the existing eID system, there is a fear that the privacy such as unnecessary attributes of the user will be disclosed. Therefore, an anonymous credential system has been proposed to enhance the user’s privacy. In the anonymous credential system, a trusted issuing organization first issues a certificate including the attributes of the user and hands it to the user. Then, in addition to the possession of the certificate, the user can anonymously prove only the necessary attributes. Previously, an anonymous credential system where the CNF formulas of the attribute can be proved has been proposed. However, as a problem, the prover cannot prove any formula including negations. Therefore, in this paper, we propose an anonymous credential system where the prover can prove CNF formulas including negations. In the proposed system, by extending the generation part of the accumulator which is used in the previous system, the formulas including negations can be proved. In addition, the proposed system is implemented on a PC, and the effectiveness of the proposed system is demonstrated by measuring the authentication time. |
