Abstract: Blind digital signatures were introduced by Chaum. In this paper, we show how security and blindness properties for blind digital signatures, can be simultaneously defined and satisfied, assuming an arbitrary one-way trapdoor permutation family. Thus, this paper presents the first complexity-based proof of security for blind signatures.
