Abstract :
This paper first reviews covert timing channels with network packet frequencies as information carriers. Then, based on the study of communication and statistical models, it proposes a method to detect an enhanced covert timing channel and its use of carrier frequencies. With the help of MATLAB for simulation, several experiments have been conducted for the verification of the proposed method.
