I didn't think that WPA2 suffered from such flaws. This is surprising.

Edit: Apparently WPA2 using TKIP is vulnerable, but WPA2 using AES is not vulnerable. That is probably what they're referring to. At least I hope so.

Bitcoin combines money, the wrongest thing in the world, with software, the easiest thing in the world to get wrong.

AES is still vulnerable. It's a problem with key exchange. During the initial handshake, the session key is generated by hashing the pre-shared key concatenated with a random number that is transmitted from the AP to the client unencrypted. Anyone who intercepts the random number can generate the session key if they also have the pre-shared key.

EFF proposes doing the key exchange using public-key cryptography, which would be secure as long as you know the AP's public key. If you don't know the AP's public key, then it's not any more secure.

Diving into my wireless router, I find that there are options built into it for a 'captive portal' like one would encounter in a public hotspot.  Wifidog seems to be able to supply my needs fine, with just a splash clickthrough screen and copious logging and stats.  However, it seems to require an outside server for the spash and clickthrough portion.  Does anyone know of a cheap/free solution for this?  I want users to see the disclaimer, references to the EFF open wireless movement, and notice of logging of activities.  I do have a linux machine on the same intranet, using the same router but wired, so that might be a solution.

"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."

- Carroll Quigley, CFR member, mentor to Bill Clinton, from 'Tragedy And Hope'
