  • Patent number: 11509636
    Abstract: Various embodiments are directed to a system and method for establishing a secure communication pathway between a network-connected device and a computing platform. Such configurations encompass encrypting a device-specific installation package passed to the device using a device-generated cryptography key, verifying the identity of the computing platform at the device, encrypting a response message via a platform-generated cryptography key, transmitting the response message to the computing platform, verifying characteristics of the device via the response message, and establishing a secure communication platform upon verification of the device.

  • Publication number: 20220138333
    Abstract: To determine whether an IoT system connected with a network environment (e.g., the internet) is compromised, a networked Trust as a Service (TaaS) server receives system data indicative of various characteristics of the IoT system, wherein the system data is harvested by a software agent installed on the IoT system. The TaaS server initially establishes a baseline characteristics profile for the IoT system, such that subsequently received system data from the software agent may be compared against the baseline characteristics profile to quickly identify discrepancies between the originally established baseline characteristics profile and current operating characteristics of the system. Such discrepancies may be caused by desirable software updates, in which case the discrepancies may be integrated into the baseline characteristics profile, or the discrepancies may result from the IoT system being undesirably compromised.

  • Patent number: 11170119
    Abstract: Providing an objective measure of trust in data provided by an Industrial Internet of Things (IIoT) device and/or a plurality of IIoT devices at a particular location so as to provide an aggregated objective measure of trust in data provided by the particular location.

  • Patent number: 10867055
    Abstract: Providing an objective measure of trust in data provided by an Industrial Internet of Things (IIoT) device utilizes an objective trust indicator generated based at least in part on baseline device characteristics and corresponding monitored/observed device characteristics. These device characteristics may comprise device hardware characteristics, device software characteristics, application software characteristics (of software installed on the device), and/or device behavior characteristics. The trust indicator is determined by comparing a match vector indicative of weighted scores for the baseline device characteristics relative to a generated monitored characteristics vector indicative of differences between baseline and monitored device characteristics, and determining a directional difference between the match vector and the monitored characteristics vector.

  • Patent number: 8515079
    Abstract: In one embodiment, a rekey distribution process transmits, from a key server, a multicast probe message intended to be received by at least one group member device. The rekey distribution process also receives, at the key server, an acknowledgement message from each group member device that received the multicast probe message. In turn, the rekey distribution process transmits, from the key server, a multicast rekey data message intended to be received by each group member device from which the key server received an acknowledgment message. Furthermore, the rekey distribution process transmits, from the key server, a unicast rekey data message to each group member device from which the key server did not receive an acknowledgment message.

  • Patent number: 8347376
    Abstract: Techniques for distributing a new communication key within a group virtual private network (VPN) are provided. A key distribution service determines that a new communication key for a VPN is to be distributed to members of the VPN. The new communication key is sent individually in a unique and separate message to each of the members. The key distribution service also maintains records to determine which of the members have and have not successfully received the new communication key.
