Exactly, the point is.. there are many students (like me) and other possible contributors out there who are not able to spend 1000 US Dollars for buying a USRP1+Daughterboards+Antenna + UPS to Europe (delivery itself is about 100USD + taxes?) So the benefit of new hardware would definitely be that much more people would buy this diy-pcb + components, solder it themselves and are then able to contribute software to the project without having spent 1000$. How do you want people to contribute code to the airprobe project if they have not enough money to buy a USRP? A downlink "module" would be sufficient for the beginning, a "uplink module" could follow if needed. But at first a less expensive rx-module, designed especially for receiving gsm signals, could help the project to rapidly get more contributors. Btw. I wouldn't say that the hardware is "that" simple, as Harald Welte stated, professional measurement equipment is necessary, all guys at university may be able to use stuff from the faculty, but it may still be very hard to coordinate such a project just over the net/mailinglist. ___ A51 mailing list A51@lists.reflextor.com http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51

I think that there's a lot of excitement because Enemy-of-the-State-like call interception seems to be at the fingertips of the masses, but for most people that would like to try it out, the hardware setup is prohibitively expensive - leading to more or less accurate brainstorming for cheaper solutions. The tradeoff between spending development time on hardware and spending money on USRP is easy with goals such as demonstrating A5/1 brokenness or creating open source GSM software, however not so easy for individuals with anything less than a very strong interest. OsmocomBB is a fantastic development, making consumer electronics usable for open source GSM development and experiments. But it seems to me that it might be(come) difficult to source the relevant hardware which is also problematic, just in another way, for everyone but core contributors. > The state of airprobe's various receivers (tvoid, gsmsp, gsm-receiver) has > only improved marginally throughout the last years.

And/or hardware. I think OpenBTS and OsmocomBB are two amazing sources of code, and there is clearly overlap among them and airprobe - or at least there should be!

That's the point I was trying to raise when I suggested that efforts would be better spend exploiting to the full extend the HW we have rather than building new one. A single USRP with 2 db should be able to capture at least 3 MHz of uplink and downlink synchronized. If the ARFCN of your hopping sequence fit into those 3 MHz, then you're good. As mentionned OpenBTS laurent's decomposition demod seems to be way better than the current one (from the limited testing I did). Another benefit is that you can exploit CUDA _a_lot_ for the first stage of a multi ARFCN receiver. (when you do the math you'll see that things fit together nicely and you end up with a bunch of complex MACs and at the output you have N channels of I/Q samples pre-multiplied for laurent's). But yeah ... need time to implement all that :( > Next problem is: If you ever want to tune into the uplink, you need custom > hardware as the filters for the frequencies are reversed.

Well, on that point I don't agree ... 1) You can just ignore the filter: Works fine as long as the handset is close enough, or if you're using a good antenna. Those filter are just not that good. 2) You can do it 'brutally' and put a pre-amp in front of the antenna. Definitely not the cleanest solution but it'll work. And if you want to bring the uplink and the downlink 'in the same ballpark', just add a filter to attenuate downlink as well. 3) There are simple SMD 'baluns' that will convert the unbalanced 50ohm to balanced 50ohm with a pinout close enough that soldering them in place of the other could works. They (that one I haven't tried yet, but I'll order a couple and see what I can work out when I have some spare time) The hardware is definitely limited but for demonstration purposes it can do the trick IMHO. Workaround 1 is good for that use-case. Workaround 2 is an option if you already have the parts laying around from other GSM experiments. The option 3 ... well not tested yet so can't really say anything. OTOH, as you said creating a brand new board based on those chips would be a loss of time.

It would certainly > be a lot more fun than just paying for the hardware :) Well, you can try to look at the work that we've been doing as part of OsmocomBB (http://bb.osmocom.org/). We've done all the code you need to drive the transceiver of the TI Calypso chipset (TRF6151 / Rita), the analog baseband (TWL3025 / Iota) and the digital baseband (Calypso / HERCROM400G2). Next problem is: If you ever want to tune into the uplink, you need custom hardware as the filters for the frequencies are reversed. Plus, it is impossible to find any SAW filters for the reverse bands in the same or similar mechanical dimensions - not even speaking of the same impedance and balanced/unbalanced-ness as needed. Thus, it is impossible to simply replace the filters on existing hardware. More modern GSM phone designs use a 'frontend module', i.e. an integrated component that contains the RF transceiver, the filters and often also the PA. In such a module, you simply cannot change the filter characteristics anymore. Also, I would not waste time at developing your own hardware based on an old / end-of-life RF transceiver. Don't underestimate the time you will have to spend on doing analog RF design at frequencies that come close to 2GHz. Without the proper skills/experience and particularly measurement equipment, you will not be able to design something that will be close to the performance of a commercial handset. I've analyzed this long enough and I think it's simply not worth putting so much time and effort into something that inevitably only very few people will show an interest in.

Guys, what is wrong with you (sorry)? I've been doing software development related to GSM for quite some time now, have contributed to airprobe and am now mostly working on OpenBSC and OsmocomBB. The problem with regard to practical GSM A5 cracking is not that hardware is too expensive or that you need to do your own custom hardware. The problem is that everybody wants a solution / software / ... but very few people actually are willing to put in the required time, sit down, get their hands dirty and make it work. The state of airprobe's various receivers (tvoid, gsmsp, gsm-receiver) has only improved marginally throughout the last years. Even today, they are nothing more than a proof of concept. They're far from what somebody would want to do actual real-world intercept. They don't even support the various GSM channel types, they don't contain the neccessarry frequency / gain control loops for long-time reception, ... This has all been clear for years. Work in this area is completely unrelated to the actual A5/1 cracking and the rainbow tables. There was no dependency on the rainbow tables needing to be completed before work on the airprobe receiver code could have been done. During the same timeframe, a really great Free Software GSM receiver implementation has been released publicly: That of OpenBTS. Yet, nobody has lifted a finger and transformed that implementation (and its contained laurent approximation based demodulation code) into a new airprobe receiver. Piotr is one of the few guys who actually contributed, and I'd like to express my gratitude for his work. But whether you use a USRP2, a USD 20,000 military SDR or a small custom cheap board will not change the fact that somebody still needs to write good demodulaton/decoding software.

Re: [A51] Reporting in..
Yes, it's not about rushing to buy big and expensive hardware, it's about rather building something minimal and less expensive, than buying two ursp's. We would only have to plan and produce the pcb's altogether. Maybe the ordering of the components could also be done together for getting a better price, but that's not absolutely necessary. Especially for people from Europe ( particularly students ;) ), the USRP is a little bit too expensive (in my opinion). What do you think?

Re: [A51] Reporting in..
I think this is one of those subjects which could be debated over and over, but really only practical tests will ever provide real proof that a method does or doesn't work. Yes, it would take a considerable amount of time, but you also have to factor in the amount of knowledge you would gain by effectively building your own hardware to replace that of the USRP. Obviously, using old hardware would probably limit you to only a few channels at a time, but at the same time, if you wanted to watch the whole GSM spectrum, you'd need more than just a single USRP, and that's when it starts getting expensive! Sometimes, these projects aren't just about the end goal, but also how much fun you have and what you learn along the way, you know?

[A51] Kraken now on GPU
I just finished a major overhaul of the ATI shared library, and Kraken is now able to take advantage of the speed that is offered by the GPU. The work is not finished yet, as I want to further reduce latency by cracking several bursts in parallel, this will better utilize the GPU pipeline. At any rate I have it to the point where disk IO is the bottleneck, and to my dismay I discovered that 2 of my disks were much slower than the others, and a job will only go as fast as the slowest disk allows for. It could be the motherboard / controller, or the disks themselves. I need to investigate. Kraken will only load the ATI shared library if it is present, so A5Ati.so will have to be placed manually in the working directory (same as kraken) and work will automatically offloaded to the GPU. The final keysearch is still done on the CPU, but this is limited to just 1 round of the rainbow table, the GPU handles the rest. As for distribution of the tables, I have gotten several requests for having disks shipped, payed for with PayPal. I am not sure I really trust this company to not freeze the accounts if someone complains about the contents of "ext3 preformatted 2TB disks." I should be able to deliver these at cost for ~250 USD, this includes Norwegian sales tax (25%) which I haven't found a way to defray. But perhaps someone on the list could do better than this and set up shop in a country where overall costs are lower?
