Interesting News

Apparently , a cryptologist recently applied his training to physical locks and discovered that it's fairly simple to derive a master key, if you have one of the uh, non-master keys. So if an apartment building is has a master key, anyone in the apartment could use their key to make a master and access the rest of the apartments.

Apparently locksmiths have known about this for a while but didn't figure it was a security risk. The guy was wise enough to warn law enforcement officials months before publishing. In case you're interested in the paper, author is Matt Blaze, and he works for AT&T Labs-Research. There's a NYTimes areticle on it as well.
