Improvement of a Proxy Blind Multi-Signature Scheme

Abstract:

In this paper, the proxy blind multi-signature scheme proposed by Hu was analyzed, and we show that the scheme is not secure against the attack which the signature requester can tamper with the proxy warrant. In order to overcome the defect, we improve the proxy blind multi-signature scheme. The improved scheme can resist the attack, and meet integrity, unforgeability, verifiability, strong blind. This improved scheme is more secure and practicable, and suitable for electronic commerce.
