A New Digital Multilevel Proxy Signature Scheme Based on Elliptic Curve Cryptography

摘要

Based on the analysis of elliptic curve digital signature algorithm(ECDSA), aiming at multilevel proxy signature in which the original signer delegates the digital signature authority to several proxies and its security demands, a new multilevel proxysignature scheme based on elliptic curve discrete logarithm problemC ECDLP) is presented and its security are proved.
