Abstract:

A new pairing based mutual authentication scheme using USB Key is proposed. To enhance the security of the authentication system, our proposed scheme using the technique of double private keys can accomplish the registration and the authentication phase separately. The scheme integrates both the advantage of the bilinear map cryptography and the USB Key technology based on security chips. It is resilient to replay, forgery, maninthemiddle attacks and insider attacks.
