Abstract
A network device receives, from a node in an Internet-of-Things (IoT) network, an access request for a user authenticated via the node and identifies the access request as from either of a trusted node or an untrusted node in the IoT network. When the access request is from an untrusted node, the network device identifies a hash key for the access request, wherein the hash key is derived from an access list for the IoT network; broadcasts the hash key to other trusted nodes in the IoT network; and validates the access request based on a solution consensus from the other trusted nodes. When the access request is from a trusted node, the network device confirms mutual trust with the trusted node via an encrypted key exchange, and validates the access request based on the mutual trust with the trusted node.
