Some embodiments of the invention provide a method for a trusted (or originator) device to modify the security state of a target device (e.g., unlocking the device) based on a securing ranging operation (e.g., determining a distance, proximity, etc.). The method of some embodiments exchanges messages as a part of a ranging operation in order to determine whether the trusted and target devices are within a specified range of each other before allowing the trusted device to modify the security state of the target device. In some embodiments, the messages are derived by both devices based on a shared secret and are used to verify the source of ranging signals used for the ranging operation. In some embodiments, the method is performed using multiple different frequency bands.

A vehicle control device is provided. The vehicle control device includes a terminal device authentication unit that determines whether a terminal device of a user registered as a user of a vehicle, in advance, is present around or within the vehicle. The vehicle control device also includes a communication unit that communicates with the terminal device. Also included in the vehicle control device is a control unit that causes a display device provided in the vehicle to output a screen for setting communication between the communication unit and the terminal device. The display device outputs the screen in a case where it is determined by the terminal device authentication unit that the terminal device is present and the display device is started up.

A global resource locator (GRL) device can be used to track a physical asset. The GRL device can a semiconductor chip with a processor and a timing device.
