Abstract
A method for remotely bonding a companion device to an implanted medical device to achieve long-term encrypted and authenticated communication channel, that is resilient to companion device failure or compromise and hence mitigates the risk or need for unplanned, revision surgery and/or premature device explantation. Through use of a shared cryptographic key between the two systems, the companion device may request an encrypted challenge number from the implant. Completing the challenge via transmitting an encrypted validation number permits the implanted medical device to bond and perform a new long-term key exchange. The shared cryptographic key can be changed as well, in event of compromise or other adverse event, using a described device firmware update procedure.
