First Claim
Patent Images
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 sensor control device or a package for the sensor control device, and 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; and
if the private key is authenticated, reading sensed analyte data from the sensor control device by the reader 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.
