  • Patent number: 10412074
    Abstract: In one embodiment, a first device in a network receives information regarding one or more nodes in the network. The first device determines a property of the one or more nodes based on the received information. The first device determines a degree of trustworthiness of the one or more nodes based on the received information. The first device attests to the determined property and degree of trustworthiness of the one or more nodes to a verification device. The verification device is configured to verify the attested property and degree of trustworthiness.
    Type: Grant

  • Patent number: 10049213
    Abstract: In one embodiment, a device in a network joins a fog-based malware defense cluster comprising one or more peer devices. The device and each peer device in the cluster are configured to execute a different set of local malware scanners. The device receives a file flagged as suspicious by a node in the network associated with the device. The device determines whether the local malware scanners of the device are able to scan the file. The device sends an assessment request to one or more of the peer devices in the malware defense cluster, in response to determining that the local malware scanners of the device are unable to scan the file.

  • Patent number: 9685086
    Abstract: In one embodiment, a device sends collision avoidance safety messages to prevent potential collisions between vehicles and the portable electronic device. The device determines whether a current or predicted future location of the device intersects an action zone. An action zone corresponds to a geographic area in which a potential collision may occur between a vehicle and the device. The device adjusts a broadcast rate for the collision avoidance safety messages based on whether the device determines that the current or predicted future location of the device intersects an action zone.

  • Patent number: 9450951
    Abstract: In one embodiment, a device and a services provisioning system establish an over-the-air connection with each other, and perform device posture validation to obtain a unique identification (ID) of the device at the provisioning system. The device and provisioning system then participate in device and user authentication in response to a confirmed unique ID by a backend access control system, where the device generates a secure key pair after successful user authentication. In response to the device being approved for services (e.g., checked by the provisioning system via a registration system), the provisioning system provides a root certificate to the device, and the device sends a certificate enrollment request back to the provisioning system. In response to a certificate authority signing the certificate request, the provisioning system returns a valid certificate to the device, and the valid certificate is installed on the device.
