Abstract
Embodiments of network devices for access control are described. In some embodiments, an access control processor of a first node receives a request from a requestor node on an unsecure network to join a group of nodes on a secure network, where the first node coordinates network activities of the group of nodes including a plurality of partitioned nodes of a network. In response to receiving the request, the access control processor assigns the requestor node to a first pool of the group of nodes that are configured to perform authorized modifications of data including a cryptographic hash to protect the data against unauthorized modifications. In some embodiments, the nodes can perform test scripts based on characteristics of the node, the corresponding edge device, and/or the user.
