Title: A New Proxy Signature Scheme Based on the Elliptic Curve
Abstract: Based on elliptic curve discrete logarithm problem A proxy signa ture scheme is proposed.This scheme not only satisfies seven fundamental propert ies of proxy signature, but also effectively controls the problem of delegation power misuse, which has not been satisfactorily solved at present. In this schem e, the proxy signer can sign a signature N times at most. If the proxy signer violates the condition, his private key will be revealed. So, this scheme can c ontrol the delegation power of the proxy signer.
