I am a Year 12 student attending the "Queensland Academy for Science, Mathematics and Technology" in Brisbane, Australia. 

Currently I am completing the International Baccalaureate (IB) diploma and a required task is a 4000 word independent research essay. Ever since I found out about RTL-SDR, and tools such as the HackRF, I have become very interested in software defined radio. The IB subject the essay pertains to is ITGS: Information Technology in a Global Society. 

For my paper, I have chosen to investigate the security of keyless entry systems, mainly in garages and automobiles. Specifically, I have reverse engineered the signal from a particular 433MHz rolling code keyfob using an RTL-SDR and GNURadio. Firstly I recorded the transmission, demodulated the 2-FSK signal and then decoded it based on pulse length and a certain preamble length. I then created a single shell script to automate this whole process. I have found that the rolling code is very insecure, with only 2 random bytes amongst a few predictably changing and static bytes. 

However, I require a TX capable SDR to perform a jam and replay attack (recently demonstrated by Samy Kamkar and on the Andrew Nohawk blog), and I am particularly interested in your products, the Yard Stick One and HackRF. I plan to use a Raspberry Pi to control the Yard Stick One and also perform the jamming via a TI CC1101 chip or using the Raspberry Pi GPIO and rpitx. The paper will also detail other vulnerabilities in keyless entry systems and explain the impact on society globally.

My name is Brock and I am a Computer & Information Technology masters student at Purdue University. My undergrad research was in network engineering and I am currently studying information security. Interesting projects include the hardening of security measures in an IoT agriculture monitoring system, analysis of network traffic from different IoT technologies such as Z-Wave, ZigBee, Lora/LoraWan, and narrow band.
