Abstract:
1. A method for pairing wireless nodes of a communication network, said method comprising: employing a plurality of network devices; employing a context manager node; for each of said network devices and said context manager node, employing a first communication channel including radio frequency signals and a diverse second communication channel including wireless non-radio frequency signals; at some of said network devices, collecting context information of a corresponding communication environment and transferring said collected context information to said context manager node; at said context manager node, employing said collected context information and enabling automated distributed pairing of a first node of said network devices with another second node of said network devices; adding said first node as a new node of said network devices; authenticating said new node by said context manager node before pairing said new node with said another second node; activating said new node; sending a parameter from said new node to said context manager node over said first communication channel in order to request a key; detecting said new node at said some of said network devices and reporting the detected new node to said context manager node by said some of said network devices; determining some of said some of said network devices at said context manager node; instructing said some of said some of said network devices to send the key which is encrypted by said parameter to said new node over said diverse second communication channel; receiving and decrypting the key at said new node; and employing said decrypted key at said new node to join said communication network.
