Cognitive Adaptation of Communications Systems and Networks for Situation-Aware Wireless Security Enhancement

点击翻译按钮获取中文摘要

With the ubiquitous deployment of broadband communications infrastructure and services, wireless communications is facing many emerging challenges including prominently the issue of wireless security. The unique security challenge of wireless communications is due mainly to the open and broadcast nature of radio signal propagation. While most of the wireless security risks are from the open air interface, conventional wireless security mechanisms, typically deployed at the higher layers of communications network protocol, are inadequate in addressing the specific vulnerability of radio propagation environment at physical layer. Furthermore, lacking of situational-aware security risk assessment and adaptation in security provisioning solutions in highly standardized wireless networks introduce additional security risks. As a result, these combined factors inevitably lead to vulnerable wireless technologies and infrastructures with widespread security weaknesses due to the ineffective security mechanisms.
