HARDWARE IMPLEMENTATION OF COVERT COMMUNICATION
Keywords:FPGA, Covert communication, Audio processing, Information hiding.
AbstractAlong with the development of the Internet and modern communication methods today, there are many ways to transfer secret or private information. Most of previous researches concentrate on dealing with still image and computer’s software processing. In this paper, we propose a technique to embed secret information into audio file and its hardware implementation. The LSB substitution algorithm is used and the system is realized by FPGA. The results prove that the system is capable for covert communication applications
