System and method based on gateway access control management

The invention provides a system and method based on gateway access control management, and the method comprises the steps: a client sends an SPA message to a control center, and builds a connection channel with the control center after the authentication is passed; the gateway sends an SPA message to the control center, and establishes a connection channel with the control center after the authentication is passed; the client sends an SPA message to the gateway; the gateway only responds to and authenticates the SPA message sent by the client logging in the control center, and establishes a service connection channel for data mutual transmission with the client after the authentication is passed; and the client sends a service access request to the gateway through the service connection channel, and the gateway responds to the service access request. The requirements for centralized access control strategy management and distributed access control execution are met, centralized management scheduling cannot be
