In a data collection method for a remote attestation process, a remote attestation server delivers a subscription configuration to a network device, where the subscription configuration for subscribing to information related to remote attestation performed by the network device. The remote attestation server receives the subscription information returned by the network device based on the subscription configuration.

Data collection method and device

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

This application discloses a remote attestation mode negotiation method and apparatus. Before remote attestation is performed, automatic negotiation is performed between a to-be-verified network device and a server, so that the to-be-verified network device and the server can determine, through negotiation from remote attestation modes supported by both the to-be-verified network device and the server, a remote attestation mode used to subsequently perform remote attestation between the network device and the server, and there is no need to manually statically configure a remote attestation mode for the network device and the server, thereby greatly reducing labor costs of determining the remote attestation mode. In addition, when there are a large quantity of devices, the automatic remote attestation mode negotiation method also helps configure a remote attestation mode more flexibly.
