Method and system for secure pairing of wireless devices

A method for secure pairing of wireless devices, wherein a master device (A) is deployed in a network environment (2), said method comprising the steps of:

• placing, within an operational area, a new device (B) to be securely integrated into said network environment (2), the master device (A) and the new device (B) having executed an unauthenticated key exchange with said master device (A),
• monitoring the operational area with a camera system, wherein said master device (A) has a security association (3) with the camera system (1) that monitors the operational area where said new wireless device (B) is placed,
• based on the exchanged key of the unauthenticated key exchange, said master device (A) and said new device (B) each computing a key confirmation code, wherein said camera system (1) learns said key confirmation code from said master device (A),
• said camera system (1) i) watching for devices transmitting said key confirmation code via a visual out-of-band channel (7) and ii) providing an image to said master device (A) of each said device identified by the camera system as having transmitted said key confirmation code, and
• for each image of each said device identified by the camera system as having transmitted said key confirmation code, i) making an analysis of the image to determine whether the image is of the new device (B) that performed the unauthenticated exchanged key with the master device (A), and ii) based on said analysis and determination, making an authorization decision with respect to accepting each said device as the new device (B) of said network environment (2).
