WIRELESS NODES WITH SECURITY KEY

摘要

A method of commissioning wireless node devices in a private wireless network without compromising the security of the network, and also wireless devices adapted to commission and to be commissioned in such a manner. A commission key is provided out-of-band for use in commissioning the wireless node device and an identification key is provided for uniquely identifying the wireless node device on the private wireless network. An encrypted network key for the private wireless network is also provided over the wireless medium and is decrypted using an encryption key generated from the commission key and the identification key. The decrypted network key is used to associate the wireless node device with the private wireless network. The method and devices find particular application in wireless lighting systems, and the control thereof.

1. A wireless node device adapted to associate with a private wireless network over a wireless medium, the wireless node device comprising:
memory storing a commission key and an identification key, the commission key for use in commissioning the wireless node device and the identification key comprising a unique identifier for uniquely identifying the wireless node device on the private wireless network; means for notifying the commission key out-of-band; means for notifying the identification key; means for receiving an encrypted network key for the private wireless network over the wireless medium; a processor adapted to execute:
(i) a predefined encryption algorithm to generate an encryption key by a mathematical combination of the commission key and the identification key; and,(ii) a predefined decryption algorithm to decrypt the received encrypted network key using the generated encryption key; and, a physical data transport layer adapted to utilise the decrypted network key to associate the wireless node device with the private wireless network.
