Abstract: An address verification method and a corresponding apparatus are applied to the field of communication technologies, and in particular, relate to a short-range communication technology. During specific application, a second node receives first information from a first node. The first information includes a first to-be-resolved address and a first resolving key index that are of the first node. The first resolving key index indicates a first resolving key. Then, the second node can determine an identity address of the first node based on the first resolving key index and the first to-be-resolved address. The identity address uniquely identifies the first node. The first to-be-resolved address includes verification information for verifying the first resolving key. The first resolving key corresponds to a first identity address.

Abstract: A solution for security negotiation during handover of a user equipment (UE) between different radio access technologies is provided. In the solution, the UE receives non-access stratum (NAS) security information and access stratum (AS) security information which are selected by the target system and then performs security negotiation with the target system according to the received NAS security information and AS security information. As such, the UE may obtain the key parameter information of the NAS and AS selected by a Long Term Evolution (LTE) system and perform security negotiation with the LTE system when the UE hands over from a different system, such as a Universal Terrestrial Radio Access Network (UTRAN), to the LTE system.

Abstract: This application provides an RRC connection resume method and apparatus. In the method, when a terminal moves to a target base station, the target base station may reselect, based on a capability and a requirement of the target base station, a first encryption algorithm and a first integrity protection algorithm that are used when the target base station communicates with the terminal, and send the first encryption algorithm and the first integrity protection algorithm to the terminal. On one hand, a security algorithm used for communication between the terminal and the target base station is flexibly selected. On the other hand, because the base station connected to the terminal changes, communication security can be improved by using a new encryption algorithm and integrity protection algorithm.

Abstract: This application provides a user authentication method and an apparatus. Before establishing, for a terminal device, a session used to transmit service data, an SMF entity receives a session establishment request message; determines, based on the session establishment request message, to perform user authentication on a user using the terminal device; and sends a session establishment message to a UPF entity, where the session establishment message is used to establish a first session for the terminal device, and a session attribute of the first session is: a session used to transmit only a user authentication message. Subsequently, the terminal device and an AAA server transmit the user authentication message through the first session, to complete user authentication.

Abstract: The present disclosure provides example terminal devices, road side units, and servers. One example terminal device performs operations including sending certificate request information to a certificate authority server, where the certificate request information includes identity information of the terminal device. A communication key sent by the certificate authority server is received by the terminal device. Encrypted information that is sent by a road side unit is received by the terminal device, where the encrypted information is information encrypted by using the communication key. The encrypted broadcast information is decrypted by the terminal device by using the communication key.

Abstract: A communication method and apparatus, where the method includes: A first mobility management network element in a first network obtains information about N intermediate session management network elements that are capable of serving a terminal in the first network, and determines that a combined intermediate session management network element (which is capable of providing session management in the first network and in a second network) in the N intermediate session management network elements is a first intermediate session management network element corresponding to a first session of the terminal in the first network, such that overall communication efficiency of the network is improved. For example, network address resources are reduced to simplify network planning and deployment complexity, a quantity of nodes in the network is reduced to simplify network operation and maintenance workload, and signaling between the nodes in the network is reduced to reduce network service load.
