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.
