Patent ID: 8792645

Claim:
A method comprising: a registering sensor having a secret key and an Institute for Electrical and Electronics Engineers (IEEE) address or a Media Access Control (MAC) address automatically forming a commissioning key by encrypting the IEEE or MAC address with the secret key, the registering sensor operating under an Internet Protocol version 6 over Low power Wireless Personal Area Network (6LoWPAN) operating protocol in a wireless network; the registering sensor forming a registration request including the IEEE or MAC address and the commissioning key; a co-ordinator sensor operating under the 6LoWPAN operating protocol in the wireless network receiving the wireless request for registration from the registering sensor, the co-ordinator sensor having a separate copy of the secret key; the co-ordinator sensor automatically authenticating the registering sensor via the received request for registration and the separate copy of the secret key; and the registering sensor joining the co-ordinator sensor of the wireless network under the 6LoWPAN operating protocol and wherein the secret key and IEEE address or MAC address are provided to the registering sensor and co-ordinator sensor during manufacture to ensure security wherein the common secret key or an array of secret keys are saved within a memory of the co-ordinator sensor during manufacture of the co-ordinator.
