The rapid development of Internet is pushing the e-Business to go to the front stage. Online authentication involves much more than the obvious identification and validation problem. We present here a comprehensive framework for online authentication which has several important practical benefits. Our distributed E-Business authentication scheme based on conic curve is proposed. This scheme is composed of three parts, constructing license and validating license. Because the security of license is determined by private key, not the arithmetic itself, user can not construct new license by given license and the public key as long as the private key is not leaked. Since encoding and decoding over conic are easily implement on conic curves, it has enabled our scheme to greatly enhance efficiency. We also analysis its security. The entire process guarantees the security and reliability.
