Security Analysis of a Proxy Blind Signature and Its Improved Scheme

The security of Zheng et al.'s ID-based proxy blind signature scheme from bilinear pairings is analyzed, it is found that their scheme does not possess the blindness property. A dishonest proxy signer can relate the formation process of the proxy blind signature to the unblind signature for the...
