Abstract: 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.

Abstract: A packet processing method and apparatus are provided. The method includes: on a forwarding path of an IPv6 packet, a key node (for example, a firewall) signs a packet, and a downstream apparatus of the key node verifies the signature, to determine whether the packet passes through the key node in a forwarding process. According to this application, the key node performs checking, to effectively prevent a packet which packet header is modified by attackers from bypassing the key node.

Abstract: A reference signal sequence configuration method includes: selecting, by a network device and from candidate IDs, an ID used for generating a reference signal initialization sequence for a terminal, where the candidate IDs include at least two IDs, and the selected ID does not include a scrambling ID; and generating a reference signal initialization sequence for the terminal according to the selected ID. An implementation manner of the present invention further provides a network device. In the reference signal sequence configuration method and the network device, a reference signal initialization sequence is generated according to the selected ID, thereby providing a manner of generating a reference signal initialization sequence different from the manner in the prior art.

Abstract: In a control channel resource transmission method, user equipment (UE) obtains a configuration parameter in a candidate control channel set according to a preset protocol and/or higher-layer signaling sent by a base station, where the higher-layer signaling is used to notify the configuration parameter. The UE determines an antenna port according to the obtained configuration parameter, and then receives, through the antenna port, a control channel or a control channel element sent by the base station. The base station determines the antenna port according to the same configuration parameter as that of the user equipment, and sends, by using the antenna port, the control channel or the control channel element to the user equipment.
