Blind signature is the concept to ensure anonymity of e-cion.Untracebility and unlinkability are two main propertiesof real coin, which require mimicking electronically.Proxy signature schemes allow a proxy signer to generatea proxy signature on behalf of an original signer. All theprevious proxy signature schemes are based on ElGamal-typeschemes. In this paper, we propose a new proxy blindsignature scheme based on an ID-based signature scheme,which uses bilinear pairings of elliptic curves or hyperellipticcurves.
