Abstract
Securing the information is the main goal of today’s advance digital/analogue communication systems. Different organizations used especial techniques for the securing their information, and DSSS is one of them; which stands for Direct Sequence Spread Spectrum. In this technique a code is used for securing the information, called Barker code. This code changes narrow-band information into wide-band information on transmitter side. And at receiver side the original narrow and information can be easily achieve by again using the same barker code. As in network security cryptanalyst are always in search to break the security of encrypted information, nonetheless the same thread is still present for breaking the security provided by DSSS. Here we are proposing a technique for securing the information: in cease if the attacker hijacked the information about barker code, they will still be unable to achieve the original information. So in this proposed technique we are going to use two codes, one is the original barker code, while the other one is its grey-coded code. We are using grey code here for encryption of barker code.
