Abstract: A method for operating an elevator system includes a trusted device that creates an authentication data packet having a unique, periodically changing code based on the current time. A mobile device sends a mobile request message to a server including the request for the operation of the elevator system and the authentication data packet. A server verifies the authenticity of the mobile request message based on the authentication data packet included in the mobile request message and, after the authentication data packet has been verified, sends an instruction message to the elevator controller.
