Abstract
An apparatus which encrypts data transferred through a network during a session between a client terminal and a server. The client terminal issues a channel establishment command to start the session and includes a first encryption device and a first decryption device which are both initialized at the start of the session. A server is responsive to the channel establishment command so that the server communicates with the client terminal through the network during the session. The server includes a second encryption device and a second decryption device which are initialized at the start of the session. The server also includes a random data generator which generates random data in response to the issuance of the channel establishment command by the client terminal. The random data is used to initialize the first and second encryption devices and the first and second decryption devices and to set the encryption for the session.
