Discussing lockpicking
Matt Blaze has stirred up quite a discussion in the locksmith community by publishing attacks on real (physical) locks using cryptoanalytic techniques. This has brought back the discussion about disclosure of security problems to the locksmith profession. Interestingly enough, as Matt Blaze points out, the locksmith profession used to favour disclosure.
Toool has published an interesting attack on locks that use pins. It turns out that the more expensive locks are actually easier to open–provided that they are vulnerable to the “bumping” attack described.
