Abstract：After analyzing a proxy blind signature scheme proposed by Huang et al., it was pointed out that the scheme was insecure against the original signer and signature receiver's forgery attack. To overcome the security problems existing in Huang's scheme, an improved proxy blind signature scheme was proposed. The new scheme resolved forgery attack in the former scheme and met the security requirement of proxy blind signature scheme. The analytical results prove that the new scheme is more secure and practicable, and suitable for electronic cash.
