【Abstract】 Proxy signature has quite an abroad application during our daily life. Combining with the profit of ID-based signatures with simplifying the certificates storage and manage spending, a efficient identity-based proxy signature is proposed by using the bilinear pairing defined on elliptic curves. We also make an brief analysis of its security and performance.更多还原
