Abstract
A system for securing information. The system includes a first tracking device associated with an object or an individual. In one embodiment, the first tracking device generates independently a synchronous secret key and a server generates independently the synchronous secret key. Over an insecure communication channel, the server communicates an asynchronous vector pair encrypted with the synchronous secret key with the tracking device. To securely communicate information, messages are encrypted and decrypted using the asynchronous vector pair between the tracking device and the server. To further secure message information, a set of random numbers may be further utilized with the asynchronous vector pair to further encrypt and decrypt the messages communicated between the tracking device and the server.
