Unbreakable Crypto: Store a 30-character Password In Your Subconscious Mind

MrSeb writes "A cross-disciplinary team of US neuroscientists and cryptographers have developed a password/passkey system that removes the weakest link in any security system: the human user. It's ingenious: The system still requires that you enter a password, but at no point do you actually remember the password, meaning it can't be written down and it can't be obtained via coercion or torture — i.e. rubber-hose cryptanalysis. The system, devised by Hristo Bojinov of Stanford University and friends from Northwestern and SRI, relies on implicit learning, a process by which you absorb new information — but you're completely unaware that you've actually learned anything; a bit like learning to ride a bike. The process of learning the password (or cryptographic key) involves the use of a specially crafted computer game that, funnily enough, resembles Guitar Hero. Their experimental results suggest that, after a 45 minute learning session, the 30-letter password is firmly implanted in your subconscious brain. Authentication requires that you play a round of the game — but this time, your 30-letter sequence is interspersed with other random 30-letter sequences. To pass authentication, you must reliably perform better on your sequence. Even after two weeks, it seems you are still able to recall this sequence."

    This 30-character sequence is played back to the user three times in a row, and then padded out with 18 random characters, for a total of 108 items. This sequence is repeated five times (540 items), and then there’s a short pause. This entire process is repeated six more times, for a total of 3,780 items.

    Replace 'character' with 'note' and it's clear subjects were tortured with Philip Glass for 80 hours and won't soon forget.

    The "cross-disciplinary team of US neuroscientists" came up with the most original excuse ever for why they were spending all their grant money on games consoles and all their time playing games.

    He's not kidding. I just logged onto his /. account and posted this after reading the password he posted.

    That's a bad example. How hard could it possibly be to memorize a combined 10 words?
