1. A method for authorizing analyte sensor data exchange between a first communication device associated with an analyte sensor and a second communication device configured to provide user access to analyte values and/or information derived from analyte values, comprising:
- sending a challenge value from a first communication device associated with an analyte sensor to a second communication device;
generating a first hash value in the second communication device using, at least in part, one or more of the challenge value, an identifier of the first communication device, or a key value;
sending the first hash value from the second communication device to the first communication device;
generating, using the first communication device, a second hash value and a third hash value;
comparing, using the first communication device, the second hash value and the third hash value to the first hash value; and
sending analyte sensor data only if at least one of the second hash value or the third hash values matches the first hash value.

Abstract
Systems and methods for processing, transmitting and displaying data received from an analyte sensor, such as a glucose sensor, are provided. The data can be displayed on a hand-held display device having a display such as a key fob device including a user interface, such as an LCD and one or more buttons 604 allows a user to view data, and a physical connector, such as USB port.

8. A method for transmitting data between a first communication device associated with an analyte sensor and one or more second communication devices configured to provide user access to analyte values and/or information derived from analyte values, comprising:
- receiving a request from a second communication device of the one or more second communication devices to establish a communication channel for receiving analyte sensor data from the first communication device during a transmission window; and
establishing the communication channel between the first communication device and the second communication device if a number of communication devices that previously received analyte sensor data from the first communication device during the transmission window is below a threshold. - View Dependent Claims (9, 10, 11, 12)
