Reconfigurable Radio System Test bed for security research

Technological progress on the digital processing has opened the way to a novel implementation approach for wireless communication platforms where most of the digital signal processing is done in software rather than in hardware. Such systems have been known as Software Defined Radio (SDR) or Reconfigurable Radio Systems (RRS). A typical SDR/RRS is able to execute all the radio frequency and base-band processing though software components rather then hardware components as in conventional radio communication systems. This capability provides a high level of reconfigurability and the possibility to implement a number of different algorithms for digital processing. Therefore, SDR/RRS can be used for a variety or purposes including the possibility of implementing wireless security attacks against conventional communication systems. In this technical report, we present an application of the SDR/RRS platform to implement a security attack against a DECT platform. The SDR/RRS platform has been used to implement a DECT demodulator and a processing module to eavesdrop and capture user and control data transmitted by a DECT system. The commercially available Universal Software Radio Peripheral (USRP) has been used as SDR/RRS platform for the development of the prototype. The paper presents the technical challenges and implementation details in the development of the prototype and an overview of the capabilities of the USRP to implement wireless security attacks. The SDR/RRS platform used in the project is quite versatile and it can be used for a number of other applications related to DECT or other wireless communication systems.JRC.G.6-Security technology assessmen
