Patent ID: 8336082

Claim:
A method for implementing synchronous authentication among different authentication control devices, comprising: receiving, by a slave authentication control device, authentication information of a user; acquiring, by a master authentication control device, the authentication information of the user from the slave authentication control device; sending, by the master authentication control device, the authentication information of the user to a master authentication server of the master authentication control device; if the authentication information of the user is stored in the master authentication server: performing, by the master authentication server, an authentication process of the user after receiving the authentication information of the user; returning, by the master authentication server, an authentication Success or Failure message to the master authentication control device; and forwarding, by the master authentication control device, the authentication Success or Failure message to the slave authentication control device; if the authentication information of the user is stored in the slave authentication server: sending, by the master authentication server, the authentication information of the user to the slave authentication server; performing, by the slave authentication server, an authentication process of the user according to the authentication information of the user; sending, by the slave authentication server, an authentication Success or Failure message to the master authentication server; forwarding, by master authentication server, the authentication Success or Failure message to the master authentication control device; and forwarding, by the master authentication control device, the authentication Success or Failure message to the slave authentication control device.
