Design of Transport Layer Based Hybrid Covert Channel Detection Engine

: Computer network is unpredictable due to information warfare and is prone to various attacks. Such attacks on network compromise the most important attribute, the privacy. Most of such attacks are devised using special communication channel called ``Covert Channel''. The word ``Covert'' stands for hidden or non-transparent. Network Covert Channel is a concealed communication path within legitimate network communication that clearly violates security policies laid down. The non-transparency in covert channel is also referred to as trapdoor. A trapdoor is unintended design within legitimate communication whose motto is to leak information. Subliminal channel, a variant of covert channel works similarly except that the trapdoor is set in a cryptographic algorithm. A composition of covert channel with subliminal channel is the ``Hybrid Covert Channel''. Hybrid covert channel is homogenous or heterogeneous mixture of two or more variants of covert channels ei...
