Abstract: In an implementation, a first electronic control unit (ECU) performs an operation using a first key and a first fresh value to generate a keystream; performs an exclusive OR operation using the keystream and a to-be-transmitted first plaintext packet to generate a first ciphertext packet; and sends the first ciphertext packet to a second ECU. The first fresh value is a value generated by a counter in the first ECU when the first ECU transmits a packet, and the counter is configured to record a quantity of packets transmitted by the first ECU. The first ECU transmits the first ciphertext packet to the second ECU. This can prevent the first packet transmitted by the first ECU from being eavesdropped on, and help improve confidentiality of the packet transmitted by the first ECU.

Abstract: This application provides a terminal apparatus and method for discontinuous reception (DRX) in an unlicensed band, and may be applied to a scenario in which a terminal device performs communication through a sidelink or a Uu link. A signal receive end monitors a sidelink signal and/or a downlink signal on a grant-free resource configured by a network device, and switches between a non-DRX mode and a DRX mode when a corresponding preset condition is met. Alternatively, a transmit end directly indicates a receive end to use a DRX mode or a non-DRX mode, or indirectly indicates, with assistance of a network device, a receive end to use a DRX mode or a non-DRX mode. In this way, DRX of the receive end can be implemented in a sidelink unlicensed band or a Uu link unlicensed band. This reduces power consumption of the receive end.

Abstract: A communication method, apparatus, and system are provided, to resolve problems in a conventional technology that an AKMA authentication procedure is complex and signaling overheads are large. Principles of the method are as follows: In a registration procedure of a terminal device, AKMA authentication is implicitly indicated based on primary authentication. For example, if primary authentication succeeds, it may be considered that AKMA authentication also succeeds. In addition, an AKMA temporary identifier is allocated to the terminal device after AKMA authentication succeeds. According to the method, apparatus, and system in this application, no additional AKMA authentication is required. This simplifies a procedure and reduces signaling overheads.
