Methods of IPD normalization to counteract IP timing covert channels

Abstract

Covert channels are used for information transmission in a manner that is not intended for communication and is difficult to detect. We propose a technique to prevent the information leakage via IP covert timing channels by inter-packet delays normalization in the process of packets sending. Recommendations for using the counteraction methods and choosing parameters were given. The advantage of our approach is that the covert channel is eliminated or limited preliminary, whereas state of the art methods focus on detecting active IP covert channels that may be insecure.
