Threat Analysis of GNU Software Radio

چکیده
Software defined radio (SDR) technology implements some of the functional modules of a radio system in software enabling highly flexible handsets. SDR devices may be reconfigured dynamically via the download of new software modules. Malicious or malfunctioning downloaded software present serious security risks to SDR devices and networks in which they operate. In this paper, we analyze threats pertaining to the secure execution of downloaded software. We base our analysis on the open-source implementation of GNU Software Radio. We propose mechanisms to provide the secure execution of software modules that implement radio functionality.

Enhancing Gnu Radio for Run-time Assembly of Fpga-based Accelerators
An enhanced GNU Radio flow is presented that seamlessly augments the standard GNU Radio framework with modules that reside in FPGAs, yet preserves the GNU Radio dynamics by providing full-custom radio hardware/software structures in seconds. By delegating portions of a GNU Radio flow graph to networked FPGAs, a larger class of software-defined radios can be implemented. Assembly of the signal p...

The model includes digital and analog signal processing. The emulator is implemented in GNU Radio and is intended to be used as part of a wireless network simulator.
متن کاملComputational Complexity of Signal Processing Functions in Software Radio
The increased usage of mobile communication devices has imposed a challenge of achieving efficient communication with minimum power consumption. Moreover, with the advent of software defined radios (SDR), it is highly possible that signal processing functions would be implemented in software in future mobile devices. Hence, the power consumption of these future devices will be directly related ...
متن کاملWideband Spectrum Sensing by Multistep Frequency Domain Energy Detection in GNU Radio
Wideband spectrum sensing capability can be enabled in GNU Radio, which is an open source software radio platform. In order to improve the detection performance of GNU Radio in practice, we studied its approach of wideband spectrum sensing, i.e., multistep frequency-domain energy detection. We first gave a detailed analysis of the functions and implementation details in its wideband spectrum se...
متن کاملMulti-User Spectrum Sensing based on Multitaper Method for Cognitive Environments
This paper gives a brief but comprehensive review of the Multitaper spectrum estimation method that uses the data tapers or windows in digital signal processing. Instead of using a single kind of window functions, here a cluster of window functions are mentioned, which is known as Slepian tapers. This taper family minimize leakage also, and computing them requires solving eigenvalue problems th...
