Covert channel is secret communication path, which existence is not expected in original system of design. It allows different users access to the same information, at the same time, but from different points-of-view. It is being more and more studying due to the grooming of internet. Always high-bandwidth network covert channel pose the significant risk of detection over network. Although the existing technique utilized the reserved bits of header, timestamp, initial sequence number, packet length etc for network covert channel, to some extend these have good temper resistance. But when increase their covert data capacity they becomes to fail to persist their original characteristics and vulnerable to network traffic detector. We are motivated to design to achieve a high bandwidth covert channel in network protocols. We simulated our proposed technique in ns2 simulator utilizing TCP protocol. Through experimental results, our proposed model is very high capacity covert channel with temper resistance and time efficient as compared to previous techniques.
