Cryptanalysis of a Partially Blind Signature Scheme or How to Make $100 Bills with $1 and $2 Ones


Partially blind signature scheme is a cryptographic primitive mainly used to design efficient and anonymous electronic cash systems. Due to this attractive application, some researchers have focused their interest on it. Cao, Lin and Xue recently proposed such a protocol based on RSA. In this paper we first show that this protocol does not meet the… (More)
