Abstract
A mobile commissioning device for assisting in the commissioning of wireless public-key encrypted networks, the device being provided with: means for reading the public key from a network node to be integrated in the wireless network, the channel for reading the public key being physically different to the wireless network channel for which the node is to be commissioned, means for at least temporarily storing the read public key in the device, means for transferring a public key of the commissioning device to the network node to be commissioned, the channel for transferring the public key preferably being the wireless channel for which the node is to be commissioned, and means for transferring the read public key to a trust center.
Claims34
A mobile commissioning device (CD,2) for assisting in the commissioning of wireless public-key encrypted networks, the device comprising:
- means for reading (22) the public key (NWN-PUB-KEY) from a network node (NWN,1) to be integrated in the wireless network, the channel for reading the public key (NWN-PUB-KEY) being physically different to the wireless network channel for which the node (NWN,1) is to be commissioned,
- means for at least temporarily storing the read public key (NWN-PUB-KEY) in the device,
- means (21) for transferring a provisional public (CD-PUB-KEY) key of the commissioning device (CD, 2) to the network node (NWN,1) to be commissioned, the channel for transferring the provisional public key (CD-PUB-KEY), and
- means for transferring the read public key (NWN-PUB-KEY) to a trust center (TC,3).
A network node (NWN,1) for a public-key encrypted wireless network, the node comprising:
- a means for providing (12) a public key (NWN-PUB-KEY) of the network node (NWN,1), the channel over which the public key (NWN-PUB-KEY) is provided being physically different to the wireless network channel for which the node (NWN,1) is to be commissioned,
- a storing means for storing at least temporarily a provisional public key (CD-PUB-KEY) transferred (5) to the network node (NWN,1) to be commissioned, the channel for transferring the provisional public key (CD-PUB-KEY), and a storing means for permanently storing a permanent public key (TC-PUB-KEY) transferred to the network node (NWN,1) from a trust center (TC,3).
A trust center unit (TC,3) in a network, the trust center (TC,3) comprising:
- a communication means (31) for communicating on a wireless network, wherein the trust center (TC,3) is configured to receive (6) at least one public key of a (NWN-PUB-KEY) of at least one network node (NWN,1) to be integrated in the wireless network from a mobile commissioning device (CD, 2), and wherein the trust center (TC,3) is further configured to transfer (7) its public key (TC-PUB-KEY) to the at least one network node (NWN,1),
- wherein the trust center (TC,3) is configured to additionally receive (6) at least one certificate, signed data record and/or nonce (OTR) from the mobile commissioning device (CD, 2) to transfer (7) the at least one certificate, signed data record and/or nonce (OTR) to the at least one network node (NWN,1) with the permanent public key (TC-PUB-KEY).
A method for commissioning wireless public-key encrypted networks, the method comprising the steps of:
- obtaining (4) a public key (NWN-PUB-KEY) of a network node (NWN,1), the channel over which the public key (NWN-PUB-KEY) is obtained being physically different to the wireless network channel for which the node (NWN,1) is to be commissioned,
- storing the obtained public key (NWN-PUB-KEY) to a storing means of a mobile commissioning device (CD, 2),
- transferring (5) a preliminary public key (CD-PUB-KEY) from the mobile commissioning device (CD, 2) to the network node (NWN,1),
- transferring (6) the public key (NWN-PUB-KEY) of the network node (NWN,1) from the mobile commissioning device (CD, 2) to a trust center (TC,3), and
- transferring (7) a permanent public key (TC-PUB-KEY) from the trust center to the network node (NWN, 1).
