I found this interesting talk abstract at the Blackhat conference program. The talk was delivered by Micheal Ossman who works as an information security researcher, at the institute for telecommunications sciences, U.S. Dept. of commerce. I have been thinking of this issue for some time, particularly from the point of view of GSM radio signals and the possibly nasty things that can be done with a software GSM receiver.
Radios are everywhere. We use them daily in car stereos, cordless phones, car key fobs, proximity access cards, laptops, television tuners, garage door openers, mobile phones, and headsets, to name a few. To build one of these radio devices in the traditional manner, you would need some electronic components (including, in many cases, a microprocessor), a soldering iron, and a fairly advanced knowledge of electronic circuit design. All that is changing, however, with the emergence of software radio. The digital technologies that revolutionized the audio world over last thirty years are now bringing the same revolution to the radio world. General purpose computers are becoming fast enough to function as sophisticated radio devices with minimal hardware peripherals. In the future, all radios will be software radios, and all practical wireless security tools will be implemented with software radio.
This presentation will describe the state of software radio, discuss future trends, and point out current and future applications of software radio technologies to wireless security research. Particular attention will be given to tools and resources that are available today, helping attendees without a background in RF technology to get started in the field. Practical attacks will be demonstrated using GNU Radio and the Universal Software Radio Peripheral.
