1. A method comprising:
executing an authentication protocol between a first communication device associated with a continuous analyte sensor and a second communication device associated with an analyte information display;
receiving, by the second communication device, a value associated with the first communication device;
exchanging a first parameter for executing authentication between the first communication device and the second communication device;
generating a first encrypted message using at least the first parameter and a portion of the value associated with the first communication device;
exchanging the first encrypted message between the second communication device and the first communication device;
verifying the first encrypted message to determine a status of the authentication protocol; and
generating a new encrypted message in response to the verifying.
