Abstract: This paper introduces and analyses the encrypt method in SET protocol. The encrypt method and digital signature and authentication scheme have been proposed based on the elliptic curve. Furthermore, the security of the system is analyzed and the result is get that the scheme is secure, simple and efficient.
