Combined ID-based partially blind signature and server-aided verification signature, a partially blind signature scheme with ID-based server-aided verification was presented to overcome the shortcomings of ID-based partially blind signature schemes such as strong security assumption and high computation cost. Most computing tasks of signature verification were accomplished by a server, and it greatly reduced computational overhead of verifier. Based on bilinear mapping, a partially blind signature scheme with specific ID-based server-aided verification was proposed. This scheme was proven to be secure in the standard model. Analysis results show that the proposed scheme greatly reduces computational complexity of signature verification. The proposed scheme is more efficient than Li's scheme (LI F, ZHANG M, TAKAGI T. Identity-based partially blind signature in the standard model for electronic cash. Mathematical and Computer Modelling, 2013, 58(1):196-203) and Zhang's scheme (ZHANG J, SUN Z. An ID-based server-aided verification short signature scheme avoid key escrow. Journal of Information Science and Engineering, 2013, 29(3):459-473).
