Abstract: Embodiments of this application provide a communication method and a network element device. The method includes: A first network function network element obtains integrity-protected attestation information, where the attestation information includes an attestation result and range indication information associated with the attestation result; generates a service request message when determining that a service provided by a second network function network element is to be requested; and sends the service request message to the second network function network element, where the service request message includes the attestation information and an identifier of the first network function network element. The method disclosed in this application can prevent and mitigate a potential security risk faced by a network function in a mobile communication network, especially faced by a network function implemented in a software or virtualization manner.

Abstract: This disclosure discloses a device management method, system, and apparatus. The method includes: A second device sends an identity file to a first access control node, to indicate the first access control node to store the identity file in a file system, where the identity file includes identity information of a first device and a public key of the second device. The second device receives a first identifier sent by the first access control node. The first identifier is used to read the identity file from the file system. After verification is performed on the second device and information about a device associated with the first device in association information and succeeds, the first access control node sends the identity file to the file system. The association information is stored in a database node and a blockchain.
