But can you name a drive vendor who's done anything like that in years? All DVD drive manufacturers. That's why nobody could write a driver for Linux until CSS was cracked, remember? It wasn't the mechanism that was secret so much as the key. CSS was supposed to protect someone else's data. You wouldn't give the key to *your* drive away, would you? /ji - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to [EMAIL PROTECTED]
What is a proof?
If a proof is a record of a mental journey in which one person has discovered an important truth, and then made a record of that journey adequate so that a second person can walk the same path and see the same truth, then cryptography could do with more and better proofs. If, on the other hand, a proof is an argument impressively decorated with mathematical sounding jargon, cryptography could do with a good deal fewer of them. - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to [EMAIL PROTECTED]
RE: In all the talk of super computers there is not...
True, the contestants are given extra information, though. They know ahead of time that the words make up the name of a place, or a common saying, for example. That helps decrease the entropy considerably. They also know the exact number of characters in the final answer and are able to probe multiple characters in the phrase simultaneously. If a system is setup correctly, you should never be able to get a hint as to whether you have guessed any portion of a password correctly, and you probably don't know what sort of phrase the target has chosen, so it would seem like most of the entropy-reducing information the Wheel of Fortune contestant is able to take advantage of are not available to a password cracking algorithm. --dan While 2.5 bits/word seems low, the TV game show Wheel Of Fortune is evidence that people can correctly guess phrases even when a large proportion of the letters are missing.
