Security controller for use with a portable device and a management apparatus, and corresponding security control method

摘要

A control system (1) for improving the security level of a security device (22, 23). A portable device (3) is provided with a communication function and has a portable device ID code. A security controller (10) includes a memory (13a) for recording a controller ID code. The security controller communicates with the portable device to determine whether the portable device ID code matches the controller ID code, and controls deactivation of security functions for a door lock driver (22) and an engine controller (23) based on the determination result. In response to a restriction request signal, a management apparatus (30) transmits a function restriction signal to the security controller. The security controller prohibits or restricts control of the door lock driver or the engine controller when receiving the function restriction signal and communicating with the portable device.
