I've got the 1996 second edition of
Applied Cryptography but I think Schneier is a doctor in a Bonanza when it comes to airport security. Since he is brilliant in the area of information security he must be a great thinker in the area of physical security right? I'm not so sure.
Also, he is very political in his approach to public policy and has a long term axe to grind with the U.S. government stemming from his battles over ITAR crypto export regulations.
We have a couple of mutual acquaintances, including a family member, but I've never met Mr. Schneier. I occasionally read his blog.
Still, I'm glad you mentioned
Applied Cryptography, it is very nicely done and this edition is a nostalgic read two decades later.
