An Elliptic Curve Proxy Signature Scheme
In this paper, a new controllable proxy digital signature scheme based on the elliptic curve cryptosystem is proposed to solve the problems that most of the known proxy digital signature schemes cannot provide the overall, complete,reliable control ability on the stretch of proxy digital signature power. It has the ability to provide the overall,reliable control on the using of proxy digital signing power.In addition, it has been applied for the Chinese patent of invention (200510019214.4). Furthermore, we also analyzed the computational complexity and security about the proposed scheme. The proposed scheme, which is an extension of elliptic curve cryptosystems, is beneficial for the study on the domain for the proxy digital signature. It can be applied in many domains, such as Electronic Commerce, Distributed Network Computing, etc.
