Abstract
The security of Near Field Communications (NFC) against eavesdroppers is improved by encoding a hidden key, private to an initiating device, onto the carrier wave when a target device communicates its data via the carrier. The initiating device, in possession of the hidden key, is enabled to undo the scrambling effects of the hidden key to thereby privately interpret the data encoded onto the carrier wave by the target device. In various aspects, the hidden key is a one-time-use key that is randomly generated, used, and then discarded, preventing malicious parties from gaining the hidden key to later interpret intercepted data signals.
