Secure registration and ignition of network nodes on a multi-hop wireless network

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• receive from a requesting network node identifying information;
• access, in a data store of a network-management system associated with a multi-hop wireless network, registration information of a plurality of previously registered network nodes of the multi-hop wireless network, wherein for each previously registered network node of the multi-hop wireless network:
• the registration information comprises one or more of:
• a firmware hash that was assigned to the previously registered network node when it was manufactured;
• or
• a serial number of the previously registered network node that was assigned to the previously registered network node when it was manufactured;
• the registration information was, in connection with installation of the previously registered network node:
• extracted from the previously registered network node and communicated to the network-management system as cipher text encoded with a public key;
• and
• decoded at the network-management system with a private key corresponding to the public key;
• compare the identifying information of the requesting network node with the registration information of the previously registered network nodes of the multi-hop wireless network to determine whether the requesting network node is one of the previously registered network nodes;
• if based on the comparison the requesting network node is determined to be one of the previously registered network nodes, then permit the requesting network node to join the multi-hop wireless network.

A system comprising:

• one or more processors;
• and a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to:
• receive from a requesting network node identifying information;
• access, in a data store of a network-management system associated with a multi-hop wireless network, registration information of a plurality of previously registered network nodes of the multi-hop wireless network, wherein for each previously registered network node of the multi-hop wireless network:
• the registration information comprises one or more of:
• a firmware hash that was assigned to the previously registered network node when it was manufactured;
• or
• a serial number of the previously registered network node that was assigned to the previously registered network node when it was manufactured;
• the registration information was, in connection with installation of the previously registered network node:
• extracted from the previously registered network node and communicated to the network-management system as cipher text encoded with a public key;
• and
• decoded at the network-management system with a private key corresponding to the public key;
• compare the identifying information of the requesting network node with the registration information of the previously registered network nodes of the multi-hop wireless network to determine whether the requesting network node is one of the previously registered network nodes;
• if based on the comparison the requesting network node is determined to be one of the previously registered network nodes, then permit the requesting network node to join the multi-hop wireless network.
