Abstract
The present invention provides a secret communication method, apparatus and system. The method comprises: 1) determining a neighboring encryption switching equipment shared by a first user terminal and a second user terminal, wherein the first user terminal and the second user terminal are neighboring user terminals (); 2) establishing, by the neighboring encryption switching equipment, an inter-station key for communication between the first user terminal and the second terminal (); 3) performing data secret communication between the first user terminal and the second terminal by using the inter-station key (). With the present invention, the neighboring user terminals needing to perform the secret communication can establish the inter-station key without performing identity authentication with each other, and can perform the secret communication with the inter-station key, and thereby the network load is reduced.
