Abstract: The characteristic of an information system was analyzed while covert storage channels exist. Then a covert storage channel identification method was put forward. It models the system as a labelled finite automaton and identifies the potential covert storage channels automatically. Then the existence scenarios and the information transferring processes of these channels were described. Furthermore, the calculation of the channel bandwidth was discussed.
