Collaborative Research: CT-ISG: An Integrated PHY-MAC Approach to Secure Open Access Wireless Networks

一个集成的PHY-MAC方法，以确保开放接入无线网络摘要这个合作项目提出了一个综合的研究和教育计划，以解决许多重要的严重的安全挑战，特别是在开放接入无线网络（OAWN）的低层该项目的目标是通过定义一个无处不在的安全和控制基础设施来解决OAWN中的无线安全漏洞，客户端，同时适当地检测，本地化和隔离恶意行为，并减轻其影响。一个独特的方面和该项目的主要贡献将是它的重点是保护低（PHY和MAC）层，这是特别重要的，因为较低层是任何开放无线系统的最弱链路。要做到这一点，PI将设计首先防止或至少使MAC层攻击变得困难的协议机制。如果攻击者试图攻击PHY层，则必须消耗更高的能量，这反过来又简化了攻击检测。 此外，为了对抗此类PHY层攻击，PI建议使用复杂的信令和编码技术以及PHY-MAC加密和时空调度策略。PI还将设计分布式PHY-MAC策略，执行对无线环境的持续监控，并帮助隔离异常行为。建议机制的互操作性程度与可实现的相应安全保证级别之间的关系。

An Integrated PHY-MAC approach to secure Open-Access Wireless NetworksAbstractThis collaborative project proposes an integrated research and educationalplan for addressing many important serious security challenges, especiallyat the lower layers of Open-Access Wireless Networks (OAWNs).The goal of this project is to addres wireless security vulnerabilities in OAWNsby defining an ubiquitous infrastructure for security and control that maintainsits open access nature for regular clients while appropriately detecting,localizing, and isolating malicious behavior and mitigating their impact.A unique aspect and key contribution of this project will be its focus on protecting the lower (PHY and MAC) layers through an integrated approach that has received scant prior attention in the context of OAWNs.This is particularly important since the lower layers are the weakest links of any open wireless system.To do this, the PIs will design protocol mechanisms that, first, prevent or atleast render MAC-layer attacks difficult. If an attacker would instead try toattack the PHY layer, it would have to expend significantly higher amounts ofenergy, which in turn simplifies attack detection. In addition, to combat suchPHY layer attacks, the PIs propose to use sophisticated signaling and coding techniques as well as PHY-MAC cryptographic and spatio-temporal scheduling strategies.Finally, to facilitate some of these security mechanisms, the PIs will also designdistributed PHY-MAC strategies that perform continuous monitoring of the wirelessenvironment and help isolate anomalous behavior.An important part of this project will be evaluating the tradeoffs between degreeof interoperability of proposed mechanisms with the corresponding level of security guarantees achievable.
