As FPGAs become more powerful and more power efficient there acceptance grows in the world of software defined radio (SDR). In SDR efficient sharing of resources is critical to the implementation of multiple waveforms. Partial Reconfiguration (PR) enables such technology. PR has been shown to work on large scale problems and is now well supported by some FPGA manufacturers.PR opens not only the way to the dynamic sharing of resources but also permits the implementation of security sensitive algorithms. Secure applications have many requirements that can be addressed by PR technology such as boundary monitoring and enforcing. PR however also raises a number of important security aspects due to the possibility of dynamically altering key portions of various algorithms.This project will focus on two distinct but similar problems. It will introduce and validate mechanisms to monitor and police the boundary conditions of secure algorithms such as to prohibit unwanted communications in and out of the secure box. It will also introduce mechanisms to monitor the dynamic download of code into the FPGA. A security framework test bench will be build in order to investigate these mechanisms.

随着FPGA变得越来越强大，越来越节能，软件定义无线电（SDR）的接受度也在增长。在SDR中，资源的有效共享对于实现多个波形至关重要。部分重新配置（PR）使这种技术成为可能。PR不仅为资源的动态共享开辟了道路，而且还允许安全敏感算法的实现。安全应用程序有许多需求可以通过PR技术来解决，例如边界监控和强制执行。然而，PR也提出了一些重要的安全方面，由于动态改变各种算法的关键部分的可能性。它将介绍和验证机制，以监测和警察的边界条件的安全算法，如禁止不必要的通信进出安全盒。它还将引入监控代码动态下载到FPGA的机制。一个安全框架测试台将建立，以调查这些机制。
