1. A mobile commissioning device (CD) for commissioning of a wireless lighting network, the CD comprising:

  • a sensor configured for acquiring an unencrypted public key (NWN-PUB-KEY), using a first wireless communications channel, from a lighting network node (NWN) to be integrated in the wireless lighting network;

    a memory configured for storing the NWN-PUB-KEY, wherein the memory is at least one of an internal memory or external memory of the CD, wherein the memory is also configured for storing an ownership transfer record (OTR) acquired from the NWN, and wherein the OTR is at least one of a certificate, a signed data record, or a nonce;

    a communications interface configured for transferring cryptographically a provisional first public key (CD-PUB-KEY) of the CD to the NWN using a second wireless communications channel and the stored NWN-PUB-KEY, wherein the first wireless communications channel does not operate on the wireless lighting network, and wherein the second wireless communications channel operates on the wireless lighting network; and

    the communications interface also configured for instructing the NWN on the second wireless communications channel to activate a lighting means, an operating device for the lighting means, or a sensor of the NWN, then transferring the NWN-PUB-KEY and the OTR to a trust center (TC) after instructing the NWN to activate the lighting means, an operating device for the lighting means, or a sensor of the NWN.
