An Efficient Provably Secure Certificate-Based Blind Signature Scheme

摘要

The paper proposes a new and efficient certificate-based blind signature scheme with bilinear maps combining blind signature with certificate-based encryption. The proposed scheme solves the escrow problem, simplifies the certificate management process and retains the merits of blind signature. The new scheme is provably secure, and the analysis of the scheme's security is presented, the results demonstrate that our scheme's capability achieves high level of security under the computational Diffie-Hellman complexity assumption, and the scheme is efficient.
