A Critique of 'Master Key Copying Revealed'

I've never seen such a ridiculously overhyped teaser article about a very simple 150 year old weakness. [Donald Eastlake]

Clemens, Joe, Wes, Slashdot and others have pointed yesterday to the paper by Matt Blaze on the how Master Keys can be created, all triggered by an article in the New York Times. I have to agree that the paper is an interesting read. However I hope everyone realizes, as I think Wes also tried to hint at, that these vulnerabilities are common knowledge, and have been for a long time already.  I think that a good critique to the paper was given in a message that Donald Eastlake sent on Dave Farber's IP mailing list (Donald being one of the crypto pioneers). In the message Donald shows how the trivial the techniques really are.
