NEAR FIELD TELEMETRY LINK FOR PASSING A SHARED SECRET TO ESTABLISH A SECURE RADIO FREQUENCY COMMUNICATION LINK IN A PHYSIOLOGICAL CONDITION MONITORING SYSTEM

摘要

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