Abstract
Elliptic curve digital signature is the elliptic curve analogue of the digital signature based on multiplicative groups discrete logarithm. In this paper, by using restrictive blind signature technique, we present an efficient off-line electronic cash system based on a kind of elliptic curve digital signature.
