Abstract: Owing to a growth in data traffic and the influence of the various intelligent devices, rich multimedia content and the rapid increase in the points of attachment density in the last decades, wireless security has been an active research area. While academia researchers are focused on robust and efficient transmission technologies for future wireless systems such as heterogeneous networks, massive antenna systems, multimedia wave, etc., industry is undertaking at the same time 5G standardization. Regardless of how complex any wireless system becomes, the issue of security should always be approached and managed in a structured and uniform way. Security can be viewed through different levels (content, communication, network) as well as from a lot of different requirement perspectives (user, network, service). Increasing demand of users for various wireless multimedia communication services has led to the development and to the coexistence of different and often incompatible technologies with unique applications and characteristics.Service or network providers planning implementation of security mechanisms need to consider the nature of the security treat, the intensity of the security needed, the location of security solutions, the cost of available mechanisms, and the speed of mechanisms . This Plenary Lecture provides survey on challenging issues in emerging wireless networks and is organized as follows. The starting points are general security issues and requirements. Security aspects at physical layer are identified as a promising strategy that provides secure wireless transmission by exploiting the imperfections of the communications medium. Mobile networks are reliable and secure platform for voice communication. With the implementation of next generation mobile networks comes the need to open up these closely guarded networks to a much more diverse set of users and multimedia services. That was the motivation to deal with the security aspects in emerging mobile networks together with cognitive radio and direct communications as promising solutions for an efficient utilization of service frequency spectrum. In the second part of this presentation, improvement against eavesdropping attacks in order to reduce the probability of occurrence of an intercept event is analyzed. The focus is on the physical layer security enhancement through diversity techniques, including multiple - input multiple -output (MIMO), multi user diversity and cooperative diversity.
