Abstract
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.
