摘要: A partially blind signature is a variant of the blind signature. The partially blind signature scheme allows a signer to sign a partially blind message that explicitly includes the pre-agreed information. In 2005, Chow et al. first proposed an ID-based partially blind signature scheme with bilinear pairings. ID-based public key systems with bilinear pairings defined on elliptic curves offer a flexible approach to achieve both simplifying the certificate management and reducing the computational cost. However, their scheme is time-consuming for requesters (or clients) with mobile devices. In 2007, Hu and Huang proposed an efficient ID-based partially blind signature scheme based on bilinear pairings. They claimed that the proposed scheme is provably secure under the random oracle model. However, this paper shows that the Hu-Huang scheme suffers from forgery attacks. Index Terms—Security, Partially blind signature, Bilinear pairings, Identity-based.
