In one embodiment, a process discovers network topology information of a particular computer network and creates a plurality of zones of devices in the particular computer network based on the network topology information. The process also discovers network communication activity patterns and endpoints of the particular computer network and creates a plurality of conduits between devices of the particular computer network based on the network communication activity patterns and endpoints of the particular computer network and association of the devices within the plurality of zones as described above.

Automated modeling of an industrial network

In various embodiments, a server stores a set of cryptographic keys associated with a client that includes a server-stored bootstrap key, a server-stored authentication key, and a server-stored proposed key. The server receives an authentication request from the client that includes a client-indicated bootstrap key, a client-indicated authentication key, and a client-indicated proposed key. The server makes a determination that the client is authenticated based in part on whether there is a match between the client-indicated authentication key and either the server-stored authentication key or the server-stored proposed key. The server provides, based on the determination, an authentication response to the client indicating that the client has been authenticated.

Key rotation for device application authentication

According to one or more embodiments of the disclosure, a first device in a network may obtain a satellite communication schedule indicative of when a satellite will be in communication range of the first device. The first device may communicate with the satellite according to the satellite communication schedule. The first device may receive a request for the satellite communication schedule from a second device in the network. The first device may send the satellite communication schedule to the second device, wherein the second device uses the satellite communication schedule to configure a wake schedule of the second device.

Automated configuration of device wake schedules for satellite communications

In one embodiment, a remote access manager receives an access request from a client to remotely access a device on a local network. The remote access manager generates a universally unique identifier for the access request. The remote access manager sends a response to the client having a one-time use domain name system name that is based on the universally unique identifier. The remote access manager communicates with a web proxy to authorize the client to remotely access the device.

Secure remote access to devices on overlapping subnets

A zero-touch deployment (ZTD) manager receives a first request to issue a first cryptographic token to a constrained device for establishing a communications session between the constrained device and a secured resource. The ZTD manager evaluates identity information corresponding to the constrained device and determines whether the identity information is valid. If so, the ZTD manager returns the first cryptographic token to the constrained device, where it is stored in cache memory. The ZTD manager receives a second request to obtain a second cryptographic token from the secured resource. When the second cryptographic token is provided to the secured resource, the secured resource uses this second cryptographic token to validate the first cryptographic token and to facilitate the communications session with the constrained device.

Method and apparatus for providing strong mutual authentication, encryption, and integrity for constraint devices without secure storage and PKI support

In one embodiment, a service receives a device registration request sent by an endpoint device, wherein the endpoint device executes an onboarding agent that causes the endpoint device to send the device registration request via a cellular connection to a private access point name (APN) associated with the service. The service verifies that a network address of the endpoint device from which the device registration request was sent is associated with an integrated circuit card identifier (ICCID) or international mobile equipment identity (IMEI) indicated by the device registration request. The service identifies a tenant identifier associated with the ICCID or IMEI. The service sends, based on the tenant identifier, a device registration response to the endpoint device via the private APN.

Zero-touch deployment (ZTD) of cellular IoT devices and associated trust model

In one embodiment, a device in a network receives a machine learning encoder and decoder trained by a supervisory service. The service trains the encoder and decoder using vibration measurement data sent to the service by a plurality of devices. The device trains, based on the received encoder, a classifier to determine whether vibration measurement data is indicative of a behavioral anomaly. The device receives vibration measurement data captured by a particular set of one or more vibration sensors of a monitored system. The device evaluates, using the trained decoder, the received vibration measurement data to determine whether the data is indicative of a structural anomaly in the monitored system. The device evaluates, using the trained classifier, the received vibration measurement data to determine whether the data is indicative of a behavioral anomaly in the monitored system.

IoT-based network architecture for detecting faults using vibration measurement data

In one embodiment, a sender device in a network sends a plurality of uncompressed messages to a receiver device in the network. The sender device generates a sender-side compression dictionary based on the plurality of uncompressed messages. The receiver device also generates a receiver-side compression dictionary based on the uncompressed message. The sender device obtains an approval of the sender-side compression dictionary from the receiver device by sending a checksum of the sender-side compression dictionary to the receiver device, whereby the receiver device generates the approval by comparing the checksum of the sender-side compression dictionary to a checksum of the receiver-side compression dictionary. The sender device sends a compressed message to the receiver device that is compressed using the sender-side compression dictionary, after obtaining the approval of the sender-side compression dictionary from the receiver device.

In-flight building and maintaining dictionaries for efficient compression for IoT data

In one embodiment, the system may identify a virtual network, the virtual network including a plurality of virtual entities and connections among the plurality of virtual entities. The system may automatically map each of the plurality of virtual entities to one or more resources or resource pools such that the virtual network is mapped to a physical network, wherein mapping includes allocating one or more resources or resource pools to a corresponding one of the plurality of virtual entities.

Physical resource life-cycle in a template based orchestration of end-to-end service provisioning

In one embodiment, an addressing agent determines a logical static IP addressing scheme for a computer network, the addressing scheme shared with an application server and defining a static mapping of IP addresses to particular types of application-based devices that are managed by the application server in particular physical locations within the computer network. The addressing agent determines a topology of the computer network indicative of application-based devices, their type, and their physical location. The addressing agent calculates a dynamic IP address for the devices based on their type and physical location as defined by the addressing scheme, and collaboratively assigns their corresponding calculated dynamic IP address. The application server can thus manage application-based devices according to whichever device of a particular type is in a particular physical location based on the addressing scheme, regardless of which particular application-based device of that particular type is in that particular physical location.
