The invention provides a security remote control system and method for industrial equipment. The system comprises industrial equipment, a control terminal and a cloud platform, wherein a security module I is arranged in the industrial equipment, a security module II is inserted into or arranged in the control terminal, the cloud platform comprises a security access gateway, a management system, aCA certificate management system and a forwarding server, and a security module III is arranged in the security access gateway. In remote control, the industrial equipment and the security access gateway perform bidirectional identity authentication and key negotiation and create a first session key; the control terminal and the security access gateway perform bidirectional identity authenticationand key negotiation and create a second session key; the control terminal and the industrial equipment perform bidirectional identity authentication and key negotiation through the forwarding serverand then create a third session key; and the control terminal performs security remote control on the industrial equipment by using the third session key through the forwarding server.
