Wireless security is one of the most important topics and attracting more and more attention from industry, research, and academia. Network system security encompasses integrity, authentication, confidentiality and non-repudiation of both user and management information. Unlike wired communication networks that have some degree of physical security, physical security in mobile wireless communication networks is impossible to achieve on wireless links (because of the broadcast nature) and therefore security attacks on information flow are the most widespread. Modification of information is possible because of the nature of the channel and the mobility of nodes. The radio channel is harsh and subject to interference, fading, multipath, and high error rates. As a result, packet losses are common even without security threats. An opponent can make use of these natural impairments to modify information and also render the information unavailable. This tutorial will address all these issues. Special attention will be paid to wireless specific issues, e.g., tradeoffs between security and power consumption, adaptively changing security protocols in response to the radio channel, etc. Secure wireless communications will certainly be part of other advances in the industry such as multimedia streaming, data storage and sharing in clouds, mobile cloud computing services, etc. This tutorial covers the topics on the recent development of security for next generation mobile wireless networks, with focusing on 4G (LTE and LTE-A) and 5G mobile wireless network systems, followed by a discussion on the challenges and open research issues for 5G wireless network security.
