It is increasingly difficult to ensure the sharing of secret information due to uncontrolled technology explosion.In particular, the field of communication engineering has undergone a phenomenal innovation and expansion.At the same time disruptive innovation has grown significantly posing threats to all the positive innovations.On gaining information via wireless systems, intruders can get around firewalls and initiate denial of service over the networks and abuse the confidentiality of legal users.Strong encryption algorithms should be designed in order to protect the perceptive information that can be transmitted between wireless devices without interception.This has paved the way for extensive research in the field of information security to mainly detect and correct datum sabotage.In this context, development of wireless systems with inbuilt security layer can be an acceptable solution against any kind of disruptive innovation.Hence, this review study focuses on integrating schemes like OFDM, CDMA and MC-CDMA with steganography and image encryption techniques to develop wireless systems with inbuilt information security feature.
