| Abstract: | In the thesis , the conception of covert channels is introduced firstly , then the technology foundation and realization theory of the existing of covert channels in the Internet communications are discussed . The covert channel technologies based on both the network communication protocols and the steganography technologies are emphatically analyzed . Finally , the development trend of the covert channel technologies is discussed , and some preserving measures to the point of network security are also presented . |
