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.
