摘要： 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.
