%X Current identity-based blind signature scheme or the security is not high, or less efficient. Aiming at the defect, through analysis for cryptography and algorithm design, this paper firstly presented an ID-based signature scheme with only one bilinear pairing without trusted PKG. Then based on the scheme, it presented an ID-based blind signature scheme with only one bilinear pairing without trusted PKG, whose strong blindness and unforgeability had been proved. The scheme had also been proved to be secure against existential forgery on adaptively chosen message and ID attack and against attack from un-trusted PKG, and be more efficient. Its security relied on the hardness of l-SDHP.
