Bluetooth Security

Gustavo Padovan — Mon, 04 Jul 2011 09:43:49 +0000

As part of the Cryptographic course with Professor Julio López for my graduation at University of Campinas – Brazil – I wrote a small article about Bluetooth Security. I also did a presentation.

The article is available here and the slides here. Please pay attention that my English is far from good and this article may contain many English errors.

Also the article is not intended to be something professional now, it lacks many good stuff, like cryptanalysis of ciphers used in Bluetooth and history of attacks to Bluetooth Security. But it is a start, I plan to update it as I have time.

So please drop me an e-mail (or a comment on this blog) if you have corrections or suggestions for the text.

Enjoy!

Google Summer of Code has come. Again!

For the second year I got accepted on the Google Summer of Code project to work with the BlueZ organization. My project this year is to work on the DUN Client. DUN is the Dial-up Network Profile, it provides access to the Internet and other dial-up services via Bluetooth. My project intends to do the DUN client only, but if I have time at the end of the project I’ll work on the DUN Server too.

The implementation will make changes in BlueZ, ConnMan and oFono. Most of the changes will be inside oFono. There, we need to use the AT command parser and the PPP stack (recently added to the oFono repo). The work consist on integrate everything and implement the missing parts of the AT command parser and the PPP stack, and the DUN agent.

On the BlueZ part the work will be the service export for DUN Data Terminal role and and the DUN Agent server to register agents and pass the RFCOMM file descriptor. For testing purposes we can use the Serial API in the beginning. That work is very similar to what we did for the HFP this year.

The ConnMan integration: ConnMan will setup the NAT and the Internet connection. The DUN integration on ConnMan is similar to the PAN integration(still a work in progress) , so we can reuse part of that implementation.

That’s it. I’ll post updates here during the development of the project. Now let me code. ;-)

Also, congratulation to the others Unicamp (University of Campinas) students that were accepted on GSoC too. :-)

GSoC meet-up at Unicamp

Last Wednesday (March 3rd) we did a talk about Google Summer of Code at Unicamp. The talk was part of the weekly talk about Free Software in the University. It was presented by mentors and students from past GSoCs. We explained how GSoC works and how one can take part on it this year. I’ll post here some photos:

Google Open Source team has just published yesterday a set of stats[1] about Google Summer of Code 2009 and Google Summer of Code during the years. The good news is that University of Campinas (Unicamp) is on the second place in number of accepted students to GSoC 2009, with 12 projects. We also are the second place in the history of the program with 37 projects. Congratulations to all guys from University of Campinas that take part on GSoC. We’ve been done a great job. Unicamp rocks! :-)
