    Abstract: Methods, devices, and systems are provided for user authentication on a gateway device located at an industrial site or facility employing user hardware tokens. The method comprises: i) at the gateway device, receiving a user request communicated via a local area network (LAN) from a user system or device connected to the LAN; ii) at the gateway device, checking whether the gateway device is operating in a disconnected operational mode in response to the user request of i); iii) at the gateway device, selectively initiating a user authentication protocol when the gateway device is operating in the disconnected operational mode, wherein the user authentication protocol uses secret information stored in a user hardware token uniquely assigned to a particular user; and iv) at the gateway device, selectively authenticating the particular user based at least in part on results of the user authentication protocol of iii).

    Abstract: The disclosure provides methods and systems for securing internet of thing systems. One method includes receiving, at a computing device, a token, wherein the token comprises a cryptographically signed list of rights that the computing device is authorized to request. The method also includes requesting, using the computing device, an action of a receiving device in an industrial location, wherein requesting the action comprises sending the token with the request to cause the receiving device to authenticate the user of the computing device and confirm the user is authorized to perform the action.

    Abstract: A system can include edge devices that include communication circuitry; and one or more security components. A method can include receiving security codes from a plurality of edge devices without accessing the Internet: comparing the security codes without accessing the Internet; and, based at least in part on the comparing, connecting the plurality of edge devices for communication without accessing the Internet. A method can include executing a trained machine learning model on an edge device; and, based at least in part on the executing, detecting a change in state of the edge device.

    Abstract: Methods, devices, and systems are provided for user authentication on a gateway device to perform steps of, receiving a user request communicated via a local area network (LAN) from a user system or device connected to the LAN, checking whether the gateway device is operating in a disconnected operational mode in response to the user request, selectively initiating a user authentication protocol when the gateway device is operating in the disconnected operational mode, wherein the user authentication protocol uses secret information stored in a user hardware token uniquely assigned to a particular user, authenticating the administrator user using the user authentication protocol that requires administrator secret information stored in a master hardware token connected to a system or device operated by the administrator user, and selectively authenticating the particular user based at least in part on results of the user authentication protocol.
