Near field telemetry link for passing a shared secret to establish a secure radio frequency communication link in a physiological condition management system

摘要

Pairing is provided between first and second wireless devices in a physiological condition management system. The first and second wireless devices are placed in proximity to initiate generation of a secret key via a random process at one of the devices and to exchange the secret key with the other device using a wireless near field communication (NFC) link. The shared secret key is then used to encrypt data for communication between the first and second wireless devices via a different secure radio frequency (RF) wireless channel.
