Abstract
A method is provided for authenticating an electronic device. The method includes obtaining a message to be sent. A plurality of error locations is determined for errors to be intentionally introduced into the message. The plurality of error locations is communicated to a verifier device. A bit at each of the error locations of the plurality of error locations is inverted in the message in the electronic device to generate a message with intentionally introduced errors. The plurality of error locations is sent to a verifier device. The message with the intentionally introduced errors is transmitted to the verifier device. The verifier device is enabled to use the plurality of error locations to authenticate the electronic device by comparing errors detected in the transmitted message to the plurality of error locations. The method provides a way to detect a clone of the electronic device.
