Systems and methods for processing and transmitting sensor data
First Claim
1. A method comprising:
- executing an authentication protocol between a first communication device associated with a continuous glucose sensor and a second communication device associated with a glucose information display;
transmitting by the second communication device to the first communication device a first encrypted message including an identifier, and a first challenge value provided by the first communication device, wherein the first encrypted message is encrypted using an encryption method based on the identifier and the first challenge value, and wherein the identifier is associated with the first communication device;
generating by the first communication device a second encrypted message using at least the information in the first encrypted message, and upon receiving the first encrypted message; and
verifying by the first communication device the first encrypted message to determine a status of the authentication protocol.

Abstract
Systems and methods for continuous measurement of an analyte in a host are provided. The system generally includes a continuous analyte sensor configured to continuously measure a concentration of analyte in a host and a sensor electronics module physically connected to the continuous analyte sensor during sensor use, wherein the sensor electronics module is further configured to directly wirelessly communicate sensor information to one or more display devices. Establishment of communication between devices can involve using a unique identifier associated with the sensor electronics module to authenticate communication. Times tracked at the sensor electronics module and the display module can be at different resolutions, and the different resolutions can be translated to facilitate communication. In addition, the frequency of establishing communication channels between the sensor electronics module and the display devices can vary depending upon whether reference calibration information is being updated.
