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

随着宽带通信基础设施和服务的普遍部署，无线通信正面临着许多新的挑战，其中突出的是无线安全问题。无线通信的独特安全挑战主要是由于无线电信号传播的开放性和广播性。虽然大多数无线安全风险来自开放空中接口，但是通常部署在通信网络协议的较高层的传统无线安全机制不足以解决物理层处的无线电传播环境的特定脆弱性。此外，在高度标准化的无线网络中的安全供应解决方案中缺乏情境感知的安全风险评估和适配引入了额外的安全风险。因此，这些综合因素不可避免地导致易受攻击的无线技术和基础设施，由于安全机制无效而具有广泛的安全弱点。拟议的NSERC发现资助计划的主要目标是通过探索自适应物理层安全增强，认知安全风险评估以及无线安全策略的情景感知优化和部署来开发变革性的无线安全技术。为了实现这一目标，无线系统和网络的各种认知适应和合作能力，以及无线系统网络的固有动态和属性的情况感知利用，将在拟议的研究和培训中进行探索。拟议的NSERC发现补助金计划的更广泛影响包括：a）它将弥合现有通信技术与日益增长的无线安全需求之间的差距; B）它将开发一种统一的方法，有效地解决无线安全和通信性能问题; c）拟议的研究将及时与高素质人员（HQP）的培训和工业合作相结合，从而通过技术创新和知识转移最大限度地发挥NSERC发现计划的影响。

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. The primary goal of the proposed NSERC Discovery Grant program is to develop transformative wireless security technologies through exploration of adaptive physical layer security enhancement, cognitive security risk evaluation, and situation-aware optimization and deployment of wireless security strategies. To achieve this goal, various cognitive adaptation and cooperation capabilities of wireless systems and networks, as well as situation-aware utilization of inherent dynamics and attributes of wireless systems networks, will be explored in the proposed research and training. The broader impacts of proposed NSERC Discovery Grant program include: a) it will bridge the gap between existing communications technologies and increasing wireless security needs; b) it will develop an unified approach that effectively tackles wireless security and communications performance; c) the proposed research will be timely integrated with training of highly qualified personnel (HQP) and industrial collaborations, thus maximize the impact of the NSERC Discovery program via technology innovation and knowledge transfer.
