This application discloses a remote attestation method and an apparatus. The method specifically includes: A first network device receives encrypted information and first measurement information of a second network device through the second network device, where the encrypted information is information obtained by encrypting second measurement information of a third network device; the first network device determines, based on the first measurement information, that the second network device is system-trusted; and the first network device decrypts the encrypted information to obtain the second measurement information.

Remote attestation method and apparatus

A packet sending method includes generating, by a network device, a first packet, and sending the first packet. The first packet includes a first packet header, a second packet header, and protected data. The first packet header includes an indication field. The indication field indicates that the first packet includes the second packet header. The second packet header includes a type field. The type field indicates a first protection protocol. The protected data is protected by using the first protection protocol.

Packet sending method, packet receiving method, and network device

A device identifier (ID) obtaining method, a terminal, and a network device, where the method includes sending, by a terminal to a network device, a first message used to obtain a device ID, where the device ID is used to globally identify the terminal uniquely, receiving, by the terminal, an encrypted key pair sent by the network device, where the key pair includes a first public key and a first private key, receiving, by the terminal, information sent by the network device, where the information is used to identify that the first public key is the device ID of the terminal, and determining, by the terminal, that the first public key is the device ID.

Device identifier obtaining method and apparatus

A method for detecting fault in a next generation network includes: establishing a tool set and a corresponding command set for detecting whether the network is connective and detecting a range of network fault; creating dynamically in a PROXY an address mapping table storing a correspondence relationship between a user identifier userid and address information of a user terminal; and upon occurrence of a fault in the network, obtaining the address information of the user terminal from the address mapping table according to the userid of the user terminal probed currently, executing the set of command according to the address information, and probing connectivity of the network between the PROXY and the user terminal. The problem that the network address transform (NAT) device and the firewall cannot be traversed may be avoided, and the fault point or range may be detected accurately in the NGN where a fault occurs.
