Security aspects of partial reconfiguration in software defined radio

随着现场可编程门阵列变得更强大和更省电，软件定义无线电(SDR)世界的接受度也越来越高。在特别提款权中，资源的有效共享对于实施多种波形至关重要。部分重新配置(PR)使这种技术成为可能。PR已被证明可以解决大规模问题，并得到了一些FPGA制造商的良好支持。PR不仅为资源的动态共享开辟了道路，而且还允许实现安全敏感的算法。安全应用程序具有许多可通过公关技术解决的要求，例如边界监控和强制执行。然而，由于动态改变各种算法的关键部分的可能性，PR也提出了许多重要的安全方面。本项目将集中于两个不同但相似的问题。它将引入和验证各种机制，以监测和监督安全算法的边界条件，例如禁止进出安全箱的有害通信。它还将引入监控代码动态下载到FPGA的机制。为了研究这些机制，将建立一个安全框架测试平台。

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.
