Patent number: 10582467Abstract: A mechanism for secure enrollment of devices with a cloud platform is provided. This serves as a foundation for securing devices, such as edge computing and internet-of-things gateways, that can be provisioned and managed from the cloud. A public key infrastructure mechanism is provided for enrollment that is split into three phases. The first and second phases of the secure enrollment process authenticate the device and ensure that the device is within agreed to manufacturing limits for the device manufacturer. The third phase of the secure enrollment process provides a long-term operating certification to the device for cloud resource access.Type: GrantFiled: October 16, 2018Date of Patent: March 3, 2020Assignee: NXP USA, Inc.Inventors: Ruchika Gupta, Xuechen Yang, Tiefei Zang, Xuelin Shi

Patent number: 10389825Abstract: In one embodiment, a system and method are disclosed for receiving, at a first network routing element, a discovery message sent via a network, where the discovery message comprises identifying information that identifies a physical location of a first network device. The method modifies the identifying information in the discovery message by adding additional information to the identifying information, where the additional information can, for example, identify a physical location of the first network routing element. Subsequent to modifying the identifying information, the method forwards the discovery message to a network element, where the network element can be, for example, either a second network routing element or a server.Type: GrantFiled: September 29, 2017Date of Patent: August 20, 2019Assignee: Cisco Technology, Inc.Inventors: Xuechen Yang, Rudy Klecka
