Abstract
(EN)
Embodiments of the present application provide a key generation method, a UE, a network device, a system, and a computer storage medium. The method comprises: obtaining an assistant key; generating this session key at least on the basis of the assistant key, and communicating with a network side on the basis of this session key, wherein the generating this session key at least on the basis of the assistant key comprises: generating this session key on the basis of a session key generated according to a long-term key and the assistant key; or generating this session key on the basis of the session key generated according to the long-term key, the assistant key, and a session key used in a previous communication with a network side.
