Patent number: 10412074Abstract: 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: GrantFiled: October 4, 2018Date of Patent: September 10, 2019Assignee: Cisco Technology, Inc.Inventors: Tao Zhang, Yi Zheng, Helder F. Antunes, Marcelo Yannuzzi, Gonzalo Salgueiro, Joseph Michael Clarke

Patent number: 10049213Abstract: 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.Type: GrantFiled: April 15, 2016Date of Patent: August 14, 2018Assignee: Cisco Technology, Inc.Inventors: Tao Zhang, Yi Zheng, Helder F. Antunes, Danyang Raymond Zheng, Jack C. Cham, Gonzalo Salgueiro, Joseph Michael Clarke

Patent number: 9685086Abstract: 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.Type: GrantFiled: May 27, 2015Date of Patent: June 20, 2017Assignee: Cisco Technology, Inc.Inventors: Tao Zhang, Helder F.

Patent number: 9450951Abstract: 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.Type: GrantFiled: December 29, 2015Date of Patent: September 20, 2016Assignee: Cisco Technology, Inc.Inventors: Plamen Nedeltchev, Helder F. Antunes, David Sisto Iacobacci, Pedro Leonardo, Parag Thakore, Gautam M. Aggarwal, Anuj Sawani
