A Provably Secure Scheme for Restrictive Partially Blind Signatures

Fuw-Yi Yang and Jinn-Ke Jan

Abstract

A secure scheme of restrictive partially blind signature was presented. The proposed scheme has several advantages over the previous scheme: 1. The scheme is provable secure against the one-more signature forgery under the adaptively parallel attack. 2. The issued signatures can be of polynomial number whereas the previous work allows only logarithmic number. 3. The scheme is more efficient than previous scheme in both communicational and computational complexities.
