An E-Cash Scheme Based on Proxy Blind Signature from Bilinear Pairings
2010
Journal of Computers
In this paper, a proxy blind signature scheme based on bilinear pairing is proposed. The proposed proxy blind signature is existential unforgeable under adaptively chosen warrant attacks and chosen message attacks upon the CDH assumptions and DBDH assumptions in the Random Oracle Model. In order to make all levels of banks issue electronic coin, the proxy blind signature scheme is applied to construct an electronic cash system. The electronic cash system holds unforgeability, unlinkability and
