| Abstract | ||
| This paper involves the manipulation of the flag field in the IP packet header for implication of a covert channel. The hidden data which are carried by the flag field are recognized at the receiver site by using a certain reference sign. This work also attempts to overcome some difficulties that face the user of IP covert channels; these are mainly concentrated on the limitation of the message length and the recognizability of the hidden data. The implementation has finally been done with the creation of DLL that is in charge of the lower level aspects, such as the extraction at Data Link level of the Ethernet packets like extracting the IP packets, manipulating the identification field, recalculating the checksum and resending them. | ||
