    摘要: A method for enrolling a node in a network including steps of: providing a hub having a network communications element, established ownership, an owner, a private key and a public key; providing a first node having a network communications element, established ownership status, a network location status, a private key and a public key; scanning an environment to identify active hub devices; selecting a most likely hub device from among identified hub devices; receiving a hub public key from the selected hub; encrypting a string using the received public key; sending the encrypted string; receiving a decrypted copy of the string; validating the hub; sending an authentication request through the hub, the request including the public key of the first node; receiving an encrypted string; decrypting the string using the node's private key; sending the decrypted string through the hub; and updating the network location status of the node.
