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. ER -
