| Abstract: | This paper firstly introduces the concept of covert channel, and then gives an overview of network-based covert channels. Next, it summarizes several typical network-based covert timing channels. Finally, it surveys the classic countermeasures in the field of network-based covert timing channels. This paper attempts to give a comprehensive outline for this research direction, and provides a useful reference for the researchers. |
