Abstract
Systems and methods are disclosed and include a processor configured to execute instructions stored in a nontransitory computer-readable medium. The instructions include generating first message authentication code (MAC) bytes based on a shared secret key. The instructions include generating first nonce bytes and an authenticated packet based on the first MAC bytes, the first nonce bytes, and a message byte. The instructions include generating a de-whitened tone byte based on the shared secret key. The instructions include generating a message packet that includes the authenticated packet and the de-whitened tone byte. Generating the message packet includes pseudo-randomly identifying a first location of the authenticated packet and inserting the de-whitened tone byte at the first location. The instructions include transmitting the message packet to the peripheral device and establishing the communication link between a portable device and a peripheral device in response to the peripheral device validating the message packet.
