METHOD AND SYSTEM FOR SECURE PAIRING OF WIRELESS DEVICES
First Claim
1. Method for secure pairing of wireless devices, wherein a master device (A) is deployed in a network environment (2), and wherein a new device (B) to be securely integrated into said network environment (2) executes an unauthenticated key exchange with said master device (A),characterized in thatsaid master device (A) has a security association (3) with a camera system (1) that monitors an operational area where said new wireless device (B) is placed,based on the exchanged key, said master device (A) and said new device (B) each compute a key confirmation code, wherein said camera system (1) learns said key confirmation code from said master device (A),said camera system (1) watches for devices transmitting said key confirmation code via a visual out-of-band channel (7) and provides images of such identified devices to said master device (A),based on an analysis of an image of a device identified by said camera system (1), an authorization decision is made with respect to accepting said identified device as new device (B) of said network environment (2).

Abstract
A method and system for securely pairing wireless devices, includes deploying a master device in a network environment, and a new device to be securely integrated into the network environment executes an unauthenticated key exchange with the master device. The master device has a security association with a camera system that monitors an operational area where the new device is placed, based on the exchanged key, the master device and the new device each compute a key confirmation code. The camera system learns the key confirmation code from the master device. The camera system watches for devices transmitting the key confirmation code and provides images of such identified devices to the master device, based on an analysis of an image of a device identified by the camera system, an authorization decision is made with respect to accepting the identified device as new device of the network environment.
