Privacy, Security, Encryption Researchers have found a weakness in the AES algorithm. They managed to come up with a clever new attack that can recover the secret key four times easier than anticipated by experts. In the last decade, many researchers have tested the security of the AES algorithm, but no flaws were found so far. The new attack applies to all versions of AES even if it used with a single key. The attack shows that finding the key of AES is four times easier than previously believed; in other words, AES-128 is more like AES-126.

Ok, impossible might not be the right word. But "exceedingly unlikely" doesn't do it justice either...

This is a little tidbit from a paper I read a while back (its a pdf - don't know where I got it from so I can't link to it)...


If you assume:

Every person on the planet owns 10 computers.

There are 7 billion people on the planet.

Each of these computers can test 1 billion key
combinations per second.

On average, you can crack the key after testing
50 percent of the possibilities.

THEN

The earth’s population can crack one
encryption key in 77,000,000,
000,000,000,000,000,000 years.


That is a bit more than "exceedingly unlikely" ;)
