Crafting IPv4 Packets using Scapy to Implement Network Steganography

Abstract: A technique used for hidden communication between two covert parties. It is an art of hidden communication. It also relates to the areas like network protocols and security for practical data hiding in communication networks using Transmission Control Protocol/Internet Protocol (TCP/IP). Network steganography uses communication protocols such as TCP/IP. Such methods make it harder to detect and eliminate. In a typical steganography using network the modification of a single network protocol occurs. Such modification can be to the Protocol Data Unit. Network steganography shelters a broad spectrum of techniques.
