在任何一个网络系统中,时间作为发送方和接收方的共享资源是无法被割断的,这使得IP时间隐通道几乎不可能被根除。通过分析现有的多种IP时间隐通道的检测方法,提出一种不需要计算伪装分布函数反函数的新型抗检测方法,提高了IP时间隐通道的抗检测性。
In any network system,the time as the shared resource between the sender and the recipient can not be cut off,which makes the IP covert timing channel almost impossible to be eradicated.This paper analyzed a variety of existing detection methods on IP covert timing channel,and presented an new anti-detection methods without calculating inverse function of distribution function to enhance the anti-detection of hidden channels.
