Method and system for securing communication links using enhanced authentication

Abstract:

A method and system for securing CSI and DSI links using enhanced authentication and cloud tracking are disclosed. According to one embodiment, a method comprises receiving at the receiving device an encrypted information signal from the transmitting device. The encrypted information signal includes a unique identifier of the transmitting device. The method further comprises testing whether a whitelist at the receiving device includes the unique identifier of the transmitting device. The encrypted information signal is decrypted producing a retrieved information signal only if the whitelist includes the unique identifier of the transmitting device; and otherwise terminating communication with the transmitting device.
