Abstract: Techniques for performing application-layer security are disclosed. In certain embodiments, analyte data may be obtained from an analyte sensor operatively coupled to a sensor electronics module of an analyte sensor system. Thereafter, the analyte data may be encrypted, in an application layer of a protocol stack of the sensor electronics module using a session key established between the analyte sensor system and a display device. The encrypted analyte data may then be transmitted to a display device.

Abstract: Techniques and protocols for facilitating wireless secure communications between a sensor system and one or more other devices are disclosed. In certain embodiments, the techniques and protocols include secure proximity pairing techniques with reduced power. A method for pairing an analyte sensor system and one or more display devices includes broadcasting, from the analyte sensor system, for an initial connection, a low power general advertisement including an indication indicating the low power general advertisement is for proximity pairing. The method includes receiving, from a first display device, a connection request message in response to the low power general advertisement; performing an authentication procedure with the first display device; and pairing and bonding with the first display device based on successful authentication with the first display device.

Abstract: Techniques and protocols for facilitating wired or wireless secure communications between a sensor system and one or more other devices deployed in healthcare facilities are disclosed. In certain embodiments, the techniques and protocols include secure device pairing techniques and protocols for achieving heightened security, for example, recommended in healthcare facilities. In certain embodiments, a method comprises executing, at an application layer of a sensor system, a password authenticated key exchange (PAKE) protocol with a display device to derive an authentication key; executing, at the sensor system, an authenticated pairing protocol with the display device; after the authenticating is successful, establishing an encrypted connection between the sensor system and the display device; and transmitting, from the sensor system to the display device, analyte data indicative of measured analyte levels via the encrypted connection.
