Abstract: A secure communication method and apparatus are disclosed, to ensure security of a direct communication between terminal devices. In this application, a first terminal device may receive a key generation parameter from a first network element, where the key generation parameter includes a ProSe temporary identity of the first terminal device. Then, the first terminal device may generate a first discovery key based on the key generation parameter. The first terminal device sends a ProSe request message, where the ProSe request message includes the ProSe temporary identity and a message integrity code, and the message integrity code is generated based on the discovery key. The second terminal device receives the ProSe request message, and verifies the first terminal device based on the message integrity code, to ensure the security of a direct communication between the first terminal device and the second terminal device.

Abstract: Embodiments of this application provide a communication method and an apparatus, to ensure a multicast service data packet transmission security requirement. An access device may determine a user plane security active state of a multicast DRB in a PDU session, and indicate the user plane security active state of the multicast DRB to a terminal, where the user plane security active state includes whether integrity protection is activated and/or whether confidentiality protection is activated. In addition, the access device configures a multicast PDCP layer entity based on the user plane security active state of the DRB for transmitting multicast service data. The access device may further determine a user plane security active state of a unicast DRB, indicate the user plane security active state to the terminal, and modify a unicast PDCP layer entity.

Abstract: A method for determining a user plane security algorithm, a system, and an apparatus. The method may include: a second device selects a non-null user plane confidentiality protection algorithm based on a security capability of a first device and a security capability of the second device in a case in which user plane confidentiality protection between the second device and the first device is enabled and control plane confidentiality protection between the second device and the first device is not enabled. The second device sends a first message to the first device. The first message includes first algorithm indication information indicating the user plane confidentiality protection algorithm. Therefore, the first device can obtain the non-null user plane confidentiality protection algorithm. Embodiments can be adopted to determine an effective user plane confidentiality protection algorithm, for confidentiality protecting user plane data.

Abstract: This application provides a communication method, apparatus, and system. The method includes: After a second node sends first indication information to a first node by using a message that is not security protected, the first node may request an IAB donor node to verify whether the first indication information is trustworthy, so that the first node performs a subsequent operation based on a verification result of the IAB donor node. This can eliminate a security risk in a communication process, and help improve communication quality.

Abstract: This application provides a key configuration method. A session management network element receives a request for end-to-end communication and obtains a security policy, where the security policy is determined based on at least one of: a user security requirement that is of the user equipment and that is preconfigured on a home subscriber server, a service security requirement from the user equipment, a security capability requirement supported by the user equipment, a security capability requirement from a carrier network, and a security requirement of a device on the other end of the end-to-end communication. The session management network element obtains a protection key used for protecting the end-to-end communication. The session management network element sends the security policy to the devices on two ends of the end-to-end communication.
