Title The Design and Implementation of the Covert Timing
Channel Based on the ON/OFF Algorithm
Abstract
With the computer network extensive in many fields,network security
becomes more and more serious because of openness,interaction and recourse
sharing of the Internet.Covert channels as a means of mixed attack brings great threats to network security.It helps us to better understand the inner mechanism of network attack mode by studying and analyzing the mechanism of covert channel，So as to reduce the harm that the network intrusion will bring．In addition,network covert channel is also the important means to evaluate the intrusion detection system and the safety performance of firewall means to evaluate the intrusion detection system and the safety performance of firewall system．According to TCSEC standard of the U.S．defense department，analyze to covert channel is needed when developping security system above of B2．The research based on multi-layer protocol is as follows．
Based on the introduction of technology and current development of covert channel，first introduced the mechanism of the ON / OFF algorithm, and the analysis and design method of the ON / OFF algorithm in the design of the covert channel. The program is pided into two modules of the client and server side, a detailed analysis of the implementation and function of the two modules.
Key words: Internet, Covert channel,Intrusion detection,ON / OFF algorithm
