Near-field telemetry link for establishing a secure radio frequency communication link across a shared secret in a physiological status monitoring system

摘要

A physiological condition monitoring system (eg, a continuous glucose monitoring system) includes a physiological condition meter and a physiological condition sensor. The physiological condition meter and physiological condition sensor are placed in close proximity to exchange a secret key using a near-field wireless link, which is used to encrypt data and secure a radio frequency (RF) radio channel To.
