1. A method of authentication in an in vivo analyte monitoring system, comprising:
- receiving a private key by a reader device, wherein the private key is supplied by a package for a sensor control device, wherein the sensor control device comprises a sensor and analyte monitoring circuitry and the sensor is adapted to be inserted into the body of a user;
authenticating the private key using a public key stored within the reader device;
if the reader device determines that the private key is authentic and if the sensor has been inserted into the body of the user, then;
reading, with the reader device, information indicative of an analyte level of the user from the sensor control device; and
displaying the analyte level on a display of the reader device; and
if the reader device determines that the private key is not authentic, then terminating operation of the reader device with the sensor control device.

Abstract
Systems, devices, and methods are provided that allow the authentication of devices within analyte monitoring systems. The analyte monitoring systems can be in vivo systems and can include a sensor control device with a sensor and accompanying circuitry, as well as a reader device for communicating with the sensor control device. The analyte monitoring systems can interface with a trusted computer system located at a remote site. Numerous techniques of authentication are disclosed that can enable the detection of counterfeit components, such as a counterfeit sensor control device.

8. A method of authentication in an in vivo analyte monitoring system, comprising:
-
digitally signing data with a private key, wherein the private key has a corresponding public key, wherein the digitally signed data includes at least one calibration parameter for a sensor of a sensor control device, wherein the sensor control device comprises the sensor and analyte monitoring circuitry, wherein the sensor is configured to be inserted into a body of a user, and wherein the at least one calibration parameter accounts for a variation in the sensor'"'"'s manufacturing process and a time-varying parameter of the sensor; storing the digitally signed data in the memory of the sensor control device; and storing the corresponding public key in the memory of a reader device, wherein the reader device is capable of receiving the digitally signed data from the sensor control device and wherein the reader device is programmed to verify that the digitally signed data is authentic using the public key. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
