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.

Abstract: Certain embodiments herein relate to a physiological parameter monitoring system. The system may include a sensor and sensor electronics connectable to the sensor. The system may also include a transmitter operably connected to the sensor electronics, the transmitter having or being configured to have at least a portion thereof positioned at a first location adjacent to and/or in contact with an external surface of a body of a host during a sensor session, the transmitter further configured to wirelessly transmit sensor information using human body communication. The system may further include a first display device comprising a display and a receiver, the receiver having or being configured to have at least a portion thereof positioned at a second location adjacent to and/or in contact with the external surface of the body during the sensor session, the receiver further configured to receive sensor information from the transmitter using human body communication.
