An Efficient ID-Based Restrictive Partially Blind Signature Scheme
Xiaoming Hu, Shangteng Huang · 2007
Many restrictive partially blind signatures have been proposed till now. But all existing restrictive partially blind signature schemes were constructed under certificate-based public key systems. Recently, Chen et al. proposed the first ID-based restrictive partially blind signature from bilinear pairings. However, the computational cost of their scheme is high. In this paper, we propose a new ID-based restrictive partially blind signature scheme. We analyze its efficiency and security. We claim that our scheme is simpler and more efficient than Chen et al.'s scheme. It also is provably secure in the random oracle model.
