    Abstract: This application provides a key negotiation method, apparatus, and system, and may be applied to the communications field, for example, short-range communication (including a cockpit domain). During key negotiation between a first device and a second device, the first device notifies, by using first information, the second device of all key negotiation algorithms supported by the first device, and the second device selects, from the received key negotiation algorithms supported by the first device, a key negotiation algorithm supported by the second device. In this way, the key negotiation algorithm selected by the second device is supported by both the first device and the second device.
