Restrictive partially blind signatures incorporate the idea of partially blind signatures and restrictive blind signatures, which have the property of partial blindness and restrictive blindness. The existing restrictive partially blind signature schemes were constructed under certificate-based public key cryptosystems or identity-based public key cryptosystems up to now. In this paper, we propose the first certificateless restrictive partially blind signature schemes from bilinear pairings, and prove the proposed scheme to be secure in the random oracle model.
