Abstract: Embodiments of this application provide a key generation method and a related device. The method includes: receiving, by a terminal, a first message sent by a source base station, where the first message includes a key exchange algorithm selected by a target base station and a first public key generated by the target base station; generating, by the terminal, a first shared key based on the key exchange algorithm, the first public key, and a first private key generated by the terminal; and sending, by the terminal, a second message to the target base station, where the second message includes a second public key generated by the terminal. According to the embodiments of this application, a communication latency and network load can be reduced while communication security is ensured.
