چکیده
Advances in wireless technologies provide both benefits and challenges when it comes to security. Communications over wireless channels are, by nature, insecure and easily susceptible to various kinds of threats. Despite the current efforts from academia and industry, the security paradigms protecting the confidentiality of wireless communications remain open issue. This paper seeks to provide a comprehensive survey of challenging issues and prospective techniques regarding security in emerging wireless networks. Major security aspects are analyzed through physical layer, together with security of cognitive radio and direct communications as promising solutions for an efficient utilization of scarce frequency spectrum. Key-Words: Cognitive radio networks, D2D, HetNet, LTE-A, physical layer, security, wireless networks.
