Software Defined Radio (SDR) technology has the flexibility of implementing a large part of physical layer functions in software. It is one of the major technologies that will provide broadband services to millions of US residences. However, unlike conventional radio whose RF signals are tightly regulated by FCC-certified hardware, the software components of SDR can be easily exploited by hackers to create a wide range of unauthorized waveforms to launch attacks on many security-critical wireless systems. The existing preventive software-based security counter measures are not possible to prevent the myriad of potential software security loopholes and themselves often become targets of the malware. The objective of this project is to design an effective hardware-based SDR integrity assessment and behavior regulation device named SDR Shield. SDR Shield resides between the vulnerable SDR software and the security-critical SDR hardware to detect any malicious configuration of the RF device and prevent it from being used to attack wireless systems. The SDR Shield uses side channel and communication channel information from different SDR components to detect deviations from expected execution status. SDR shield also includes a regulation circuit to enforce safety-critical properties of SDR operation. A secure update process is developed to maintain SDR shield?s flexibility and its own security. The generality of SDR Shield?s design provides a unified security mechanism for SDR design and hence can ease the burden on FCC or any future SDR design verification institutes in certifying security measures of SDR products.

软件定义的无线电（SDR）技术具有在软件中实现大部分物理层功能的灵活性。它是将为数百万美国住宅提供宽带服务的主要技术之一。 但是，与传统的无线电电台不同，其RF信号受FCC认证的硬件严格调节，黑客可以轻松利用SDR的软件组件来创建广泛的未经授权的波形，以启动对许多安全策略无线系统的攻击。现有的基于软件的安全柜台措施是不可能防止众多潜在软件安全漏洞的，并且本身常常成为恶意软件的目标。 该项目的目的是设计一个有效的基于硬件的SDR完整性评估和行为调节设备，名为SDR Shield。 SDR Shield位于脆弱的SDR软件和安全性SDR硬件之间，以检测RF设备的任何恶意配置，并防止其用于攻击无线系统。 SDR Shield使用来自不同SDR组件的侧渠道和通信通道信息来检测与预期执行状态的偏差。 SDR盾牌还包括一个调节电路，以实施SDR操作的安全至关重要性能。开发了一个安全的更新过程，以维持SDR Shield的灵活性及其自身的安全性。 SDR Shield设计的一般性为SDR设计提供了统一的安全机制，因此可以减轻FCC的负担或任何将来的SDR设计验证机构，以证明SDR产品的安全措施。
