Security in wireless networks has traditionally been considered to be an issue to be addressed at the higher layers of the network. However, with the emergence of ad hoc and other less centralized networking architectures, there has been an increase in interest in the potential of the wireless physical layer to provide communications security. Information theory provides a natural framework for the study of this issue, and consequently there has been a resurgence of interest in information-theoretic security in recent years, particularly for wireless channel models. This work has expanded on earlier ideas about secure broadcast, by examining multiple-access channels, fading, code design, source coding, authentication, network coding, and many other issues. This paper will review recent works in the field of wireless security specially taking into account the OFDM(A)-based systems, e.g, Long Term Evolution (LTE) and WiMAX.
