Description
Summary:Because of the wireless media, wireless communication is inherently more susceptible to attack. Because of the popularized use of wireless technology not only communication but business, commerce and all other transactions has also been shifted from wired to wireless paradigm. So it is important to secure wireless communication not only at higher layers but also at physical layer. No one can access neither the data nor the transmission signals to compromise the security by any means. This paper discuss one of the way through which security at the physical layer can be achieved by sending data plus noise so as to hide data behind the noise. By doing this we can fool the hacker by the noise rather than having access to the data.
