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 first group of nodes on a secure network, where the first node coordinates network activities of the first 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 first 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 access control processor initiates the authorized modifications of the data using one or more nodes assigned to the first pool and one or more nodes of a second pool of the first group of nodes.
