In wireless networks interference is considered has a major problem. So, in order to avoid the interference the authors use the technique called mixing signal (Network Coding). The problem here is there are vulnerable to possible malicious attacks. i.e., if any of the intruders knows the information of other signal in the mixed signal they can be decoded easily. In order to resolve this problem they are proposing a good secure network coding scheme batch signature for mixed signal. So with the above network coding scheme they are providing a security to the signal.
