Abstract

In recent scientific literature, network based steganography is regarded as a new research direction in the paradigm of information hiding. Few approaches have been found which embed secret information by altering the length of network packets. In this paper, the steganographic security of an existing network length based embedding algorithm has been analyzed and a new scheme has been proposed to overcome the limitation of the existing scheme. In the proposed scheme, the length of UDP datagram is modified to embed the secret data. Experimental results show that proposed scheme ensures more security than that of the existing algorithm.
