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.

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 dev
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; andverifying by the first communication device the first encrypted message to determine a status of the authentication protocol. 2. The method of claim 1, wherein the generating of the second encrypted message includes using a similar encryption method used to generate the first encryption message. 3. The method of claim 1, wherein the verifying further includes comparing the first encrypted message with the second encrypted message. 4. The method of claim 1, wherein the determination of the status further includes indicating a valid status of the authentication protocol when the second encrypted message matches with the first encrypted message. 5. The method of claim 1, wherein the authentication protocol is executed at an application layer. 6. A system for wireless communication between devices, the system comprising: a sensor electronics module operatively coupled to a continuous glucose sensor;a display device comprising a processor and a user interface, the user interface configured to receive user input and a display configured to display glucose information; whereinthe system executes an authentication protocol between the sensor electronics module and the display device; andthe display device is configured to transmit to the sensor electronics module a first encrypted message including an identifier, and a first challenge value provided by the sensor electronics module, 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 sensor electronics module; andthe sensor electronics module is configured to:generate a second encrypted message using at least the information in the first encrypted message, and upon the reception of the first encrypted message; andverify the first encrypted message to determine a status of the authentication protocol. 7. The system of claim 6, wherein the generation of the second encrypted message includes using a similar encryption method used to generate the first encrypted message. 8. The system of claim 6, wherein the verification further includes comparison of the first encrypted message with the second encrypted message. 9. The system of claim 6, wherein the determination of the status further includes indication of a valid status of the authentication protocol when the second encrypted message matches with the first encrypted message. 10. The system of claim 6, wherein the authentication protocol is executed at an application layer of the system. 11. A system for wirelessly communicating between devices, the system comprising computer-readable instructions stored in computer memory, wherein the instructions, when executed by one or more processors of the system, cause the system to: execute 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;transmit a first encrypted message including an identifier, and a first challenge value provided by the first communication device, from the second communication device to 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;generate a second encrypted message using at least the information in the first encrypted message, and upon receiving the first encrypted message by the first communication device; andverify the first encrypted message to determine a status of the authentication protocol by the first communication device. 12. The system of claim 11, wherein the instructions, when executed by the one or more processors of the system, cause the system to generate the second encrypted message using a similar encryption method used to generate the first encryption message. 13. The system of claim 11, wherein the instructions, when executed by the one or more processors of the system, cause the system to compare the first encrypted message with the second encrypted message for the verification. 14. The system of claim 11, wherein the instructions, when executed by the one or more processors of the system, cause the system to indicate a valid status of the authentication protocol when the second encrypted message matches with the first encrypted message. 15. The system of claim 11, wherein the instructions, when executed by the one or more processors of the system, cause the system to execute the authentication protocol at an application layer of the system.
