Abstract
An intelligent tracking system generally includes one or more tracking devices, some of which may be passive tracking devices. Each passive tracking device includes one or more transceivers and is energized by an energizing signal. Some of these passive tracking devices may operate in a first communication mode or a second communication mode based on the energizing signal. Some tracking devices may include encryption modules or authentication modules. Some of these devices may incorporate a bulk acoustic wave oscillator.
Claims21
A method for generating encrypted messages that are used to authenticate a tracking device by an authentication device, the method comprising:
- obtaining, by an encryption module of the passive tracking device a device identifier that uniquely identifies the tracking device;
- generating, by the encryption module, an obscured device identifier based on the device identifier and a secret pattern;
- generating, by the encryption module, a message based on the obscured device identifier;
- encrypting, by the encryption module, the message using a secret key to obtain an encrypted message;
- and
- outputting, by the encryption module, the encrypted message to a transmission module of the tracking device;
- and
- modulating, by the transmission module, a response signal that includes the encrypted message for transmission via an antenna of the tracking device.
