The process isn’t exactly as simple as putting together $40 of electronics and walking away with a vehicle. The former affects up to 100 million vehicles across the Volkswagen line, while the latter will work on models from Citroen, Peugeot, Opel, Nissan, Alfa Romero, Fiat, Mitsubishi and Ford. The research team, led by, have described two main vulnerabilities: the first requires combining a cyrptographic key from the vehicle with the signal from the owner’s fob to grant access, while the second takes advantage of the virtually ancient HiTag2 security system that was implemented in the 1990s.
#ELEKTOR SDR SHIELD SOFTWARE#
Speaking to these concerns, a soon-to-be published paper out of the University of Birmingham in the UK, states that virtually every Volkswagen sold since 1995 can be hacked and unlocked by cloning the vehicle’s keyfob via an Arduino and software defined radio (SDR). However, if you want to graduate to something more practical, try our series on GNU Radio.Īs we’ve mentioned previously, the integrity of your vehicle in an era where even your car can have a data connection could be a dubious bet at best. If you want to learn more about how SDR works, try starting with spreadsheets. Then again, having a programmable signal source on the Arduino isn’t a bad thing and compared to the older version of the board, the new board offers easier breakout for the oscillator signals. That could have led to some interesting possibilities.
#ELEKTOR SDR SHIELD PLUS#
Plus there are many capable CPU and FPGA boards that have Arduino shield-compatible layouts. That’s a shame because some of the 32-bit Arduinos might be able to do some interesting things with the right hardware. The IQ signals appear on the PC’s soundcard via a microphone or line-in jack, and don’t really route to the Arduino. We peeked at the schematic and the shield is more for letting the Arduino control the radio by changing the oscillator frequency rather than performing the SDR functions. There’s also a review video from Elektor about the board in the video, below. There’s also a series of Elektor articles about it. The board is available alone or as part of a kit that includes a book.
#ELEKTOR SDR SHIELD PC#
The Si5351-based board uses that oscillator IC to shift RF signals down to audio frequencies and then makes it available to the PC to do more processing. If you want an introduction to SDR, Elektor now has an inexpensive RF shield for the Arduino. Software-defined radio or SDR means you get the RF signal to digital as soon as possible and do everything else in software. We always thought RF electronics would be immune to that, but the last decade or two has proven us wrong.
Music synthesizers? RC controllers? Most likely, all microcontroller-based now. A project you might once have done with a 555 now probably has a cheap microcontroller in it. Microcontrollers tend to consume other kinds of electronics.
