An invention is provided for monitoring an item such as a container. The , invention includes a computer in communication with a receiver that receives signals from a remote source. A transmitter in communication with the computer receives values from the computer based on the signals received from the remote source. These values are then transmitted to a security device associated with the item, which includes an authentication table comprising a plurality of initial values. The security device then records values transmitted from the transmitter. The values can be jitter values with each , jitter value being a difference in arrival times of at least two timing signals from the same …
