The security of information in wireless communication is a hot issue for researchers throughout the technical globe and uses different techniques to secure the information. One of the techniques is Direct Sequence Spread Spectrum. In DSSS a barker code is use for converting the narrowband information signal into a much wider bandwidth. As the anti-security group is also in search of breaking chain of security for leaking out the information, so in DSSS the great threat is the breakage of the code used for spreading of the signal, if the attacker comes to know the code through somehow than all the information could be loss.
