Encrypted communication method, base station, terminal and storage medium

The embodiment of the invention provides an encrypted communication method, a base station, a terminal and a storage medium, and the method is applied to the base station, and comprises the steps: determining a second terminal which generates a physical layer key with the base station from the terminals accessing the base station under the condition of receiving a physical layer encrypted communication request sent by a first terminal; sending indication information to the first terminal and the second terminal respectively, wherein the indication information is used for indicating execution of a physical layer key generation operation between the first terminal and the second terminal; under the condition that a first physical layer key fed back by the second terminal is received, generating a first target physical layer key according to the terminal identification information of the first terminal and the first physical layer key; and executing physical layer encryption communication between the base statio
