Abstract: A transmission system includes a first security unit coupling to application ends, a second security unit coupling to a user end, and a server. The server sends a first attribute key to the first security unit based on attributes of the application ends and sends a second attribute key to the second security unit based on attributes of the user end. To enable one application end, the first security unit encrypts a session key with the first attribute key, opens a socket, and sends the encrypted session key to the server. When the second security unit receives a request for the application end, the server sends the encrypted session key to the second security unit. The second security unit decrypts the encrypted session key with the second attribute key and connects to the socket. The second security unit interchanges information with the first security unit via the session key.
