    He didn't brute force it. The only person I know of using that approach to BMW encryption is Dinan.

    He's using the same thing as everyone else. Same thing the BB flash did. If I didn't brute force it and it happened in what, a few weeks, you think he did?

    I just wanted also to mention how difficult it would be to even brute force 128-bit encrypted data. You are right in that you can use botnets to crack keys, but that's usually when you have a wordlist/rainbow dictionary - not when brute forcing an attack. When you see the numbers, even for 128-bit - it's ming boggling. Just to put this into perspective - 128-bits can have 3.4028237e+38 combinations. That's 3.4028237 * 10(with 31 trailing zeros) - in order to crack that (using data from Pentium 4 @ 3.2 GHz days, I don't feel like calculating this) - it would take ALL THE COMPUTERS (at that time) IN THE WORLD 1,440,000,000 years!!! That's ONLY looking at 25% of the keyspace, not 100%. Think about how insane that is. Of course modern computers/clusters/GPUs make processing things MUCH faster - it's definitely not on the scale of magnitude needed to cut it down a billion times to make this cost effective.

    It's obvious open flash is a cobb ripoff... Cobb did all the hard work

    So what this boils down to really is we need to call up the NSA and tell them BMW hid some Al Qaeda falafel recipe's in the TCU for the 335 AT. It'll be cracked by the time I'm done typing this sentence.

    lol - it's funny you mention this... I was just looking at this: Click here to enlarge

    I am sure they have some specialty stuff, no doubt. The thing about the NSA cracking encryption (my understanding) - it's a bit different. Instead of brute force, supposedly they used a "vulnerability" in the way random numbers are generated. It has something to do with an ellipses, and two points on that ellipse. My understanding is that when the algorithm was given to the NIST (and other math/science agencies) for vulnerability testing, it was never understood how the two points on the ellipse were determined.

    It goes on that knowing how these two points were determined would allow you to "break" the algorithm. There are articles about this if you are interested - a lot of people think that Google/MSFT/Apple just gave away their keys, or allowed a back door - but based on my understanding, it's lower level than even that. It's crazy - google "elliptic curve cryptography" + "nsa" or "sp 800-90a dual elliptic curve" to read about it... It's quite interesting if it is indeed how this all happened - it means that the scientists/mathematicians/etc. all were "secretly" in with someone that I don't want thinking I am a bad person.

    I doubt I'll even understand any of this. I'm just at the point where I understand the government can get into anything and there is nothing we can do about it. That is why offline networks make more and more sense for sensitive data. Anything connected to the internet they will get to and then say, 'oh but the terrorists.'

    They just are on another level and it's scary really. People should google how much energy the NSA uses... wtf do they have in there?

    Yep, no doubt about it - I am sure they can get in anything they please... It is scary - that's a lot of power for people to have, you could basically alter anyone's life you wanted almost without them knowing.

    I didn't know about the power consumption - this is the new thing they are/were building recently, right? The datacenter?

    Due to massive amounts of data processing, NSA is the largest electricity consumer in Maryland

    Just for the record DES is actually weak compared to current 128 bit and higher encryption. The CCA (circuit card assembly) on the picture is done with FPGAs as GPUs and broadband were not as advanced as they are now and they needed to get their massive parallel computing power somewhere.
    However, for an encryption to be strong the entropy (function of complexity and length) in the key must be high. The main reason for people being able to easily crack say 128 bit encryption is low entropy which is due to low randomness associated with human language. For instance, the best human alphanumeric passwords with characters have only about 5.5 bit entropy. The most common human language passwords are only 7 to 8 alpha characters + 1 numerical resulting in average length of 29 to 30 bit. Obviously putting 29 bit password in 128 or 256 encryption vault is problematic... In any case, a highly random 80 bit encryption is estimated to take a botnet about 1.9 x 10^6 years. This is usually the reason why people are trying to figure out the random number generators rather than brute force their way. Oh and BTW, this is exactly how the NSA did it - they basically "helped" develop the random number generators thus for them the generated keys are not truly random. That makes it way easier to deal with it. They need the huge processing power simply because the net traffic is huge...

    We can get off topic all we want. We're making more progress figuring out what the NSA is doing than anyone is with the automatic transmission for this platform.

    Yep it's way different and yes someone can help there. I'm looking forward to seeing how far I can push them reprogramming it.

    8700 rpm automatic shifts? That sounds lovely.

    I know it may have been stated a while back but what was your engine built to rev to? (OT question I know, just curious)

    This is what they told you. I personally know the algorithm and how it works. Its an exploit, nothing was cracked.
