In wireless communication, security is the main issue due to the wireless media and as intruders, hackers or attackers are increasing day by day. So, we need a system that must give the guarantee of security. As day by day, digitalization is increasing in every application and so that the speed of processors is increasing. So, to fulfill the demand of security as well as high-speed processors for fast computation, in this book various encoding technique is compared and developed a new encoding technique named as Galois Encoding technique. Galois Encoding techniques provide secure communication as well as it does the fast computation within the processors with less delay processing time. Thus, Galois encoding provides security as well as save bandwidth and fast computations.
