Comment Re:is RSA soon an open vault? (Score 1) 201

1. The NSA didn't know that it could be backdoored when they created it. So there is no backdoor, and the NSA is kicking themselves for that missed opportunity, or for the embarrassment. 2. They knew about it, but intentionally didn't create a backdoor. 3. They knew about it and created a backdoor.

From looking at the algorithm, we cannot possibly know which one is the case. Obviously it would be totally insane to use this algorithm. But that _was_ known for quite some time.

Except for the 10mil paid to RSA in secret and 2005 patent describing use of this algo for _this exact purpose_.

I doubt that. The firmware, maybe, but probably not drivers. Normally the difference between high-priced and low-priced models is that the low-priced models have some internal fuses blown, so that some of the cores are disabled. Sometimes those cores were defective, other times they disable cores just to meet the demand. It could be that they disable the cores with firmware instead of fuses, and somehow the drivers could reenable cores in the latter cases, but my guess is that the people who give the orders simply think of their precious architecture details as information that needs to be kept secret, in case the competition gets too many ideas from those details.

drivers and/or jumpers

I don't understand why these systems are set up like this, operationally it's not much different from EZ-Pass which works fine with an account based system, putting the value tracking on the cards is just asking for an upgrade treadmill even if it's well designed now, 10 years from now it will be easilly cracked. compare CPU vs GPU/FPGA/ASIC hashing advances

Because its expensive to run a lot of data over GSM links in every bus/tram in the city.
We use same system in Poland and recently a group of people (over 900!) got charged with fraud. They werent the ones selling cards, they were the users, and only stupid ones.

Someone also offers Android app that charges cards using phone buildin NFC. You pay with BTC (yes, bitcoins). Its only available over TOR :)

City has NO technical way of discovering fake cards on the meters, they only stumbled on those cards because City was upgrading older VERY broken Classic cards to never less but still broken model, they did it by offering free exchange program. Some retards tried to turn in FAKE cards :D

Try asking EA to develop a game where the US masses rise up against the legitimate authority in Washington DC (that takes place in our time) and see how well that goes.

There was a game trailer a year ago that gave me some hope.

unfortunately in the real game its the other way around and you are the bad guy killing brave freedom fighters :(
