AB  - The elliptic curve cryptosystem has more advantages than RSA or DSA such as smaller key length and low bandwidth on equivalent security strength. Recently, Yeh and Chang presented the first blind signature scheme based on the elliptic curve cryptosystem and it is a modification of Okamoto’s signature. In this paper, we propose Schnorr’s blind signature scheme based on the elliptic curve that can reduce 50% storage requirements for each signature and speed up more than 36% performance compared with Yeh-Chang’s scheme. It is more suitable for preserving anonymity applied in thin-client applications. Finally, we show that our scheme is a secure blind signature scheme.
