A method of IPD normalization to eliminate IP timing covert channels

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 eliminate the information leakage via IP timing covert channels by inter-packet delays normalization in the process of packets’ sending. The advantage of our approach is that the influence of counteraction tool on the communication channel's capacity is negligible. The novelty of the investigation undertaken is that the covert channel is eliminated preliminary, whereas state of the art methods focus on detecting active IP covert channels that may be insecure.This work was supported by the Competitiveness Program of MEPhI
