- Universal Pictures will soon release (at least in the U.S.) a movie called
- "Sneakers" that purports to be an action/adventure starring a group of
- free-lance computer security consultants. The plot centers around a
- cryptographic device. For whatever reason, I bought the book (actually
- the "novel based on the screenplay"). It was already at a Barnes and Noble
- Sale Annex in Manhattan, which might indicate how well it's selling.
-
- The details are scarce, but apparently a young, brilliant mathematician,
- Gunter Janek, has made a theoretical breakthrough in the factoring of
- very large numbers. He soon builds his algorithm into a small piece of
- hardware, and everyone in the movie ends up fighting over it.
-
- Once the good guys get the box (Robert Redford, Dan Aykroyd and Sidney
- Poitier are in the film, and they seem to match the descriptions of some of our
- loveable team of hackers) they soon have it "hooked up" to a computer.
- They dial up a Federal Reserve funds transfer machine, which is apparently
- "encrypted" and impossible to enter.
-
- I quote:
- Some of the racing characters stopped changing and gradually
- formed recognizable combinations of letters. Then some complete
- words. Then more. Soon, most of the screen was decrypted...
-
- So the Magic Black Box can decrypt anything based on a theoretical
- breakthrough and an advance in open systems and standards technology that
- won't be seen for years, if ever. It helps if the system they're breaking
- in to has a dial-up connection that does some form of encryption
- of the data stream rather than a password or any other form of
- access validation.
-
- But on to the cryptography -- the Russians/whomever they are now didn't
- fund (or eventually steal) the box, althogh they want it. A Russian
- ambassador-type eventually tells the hero (Redford?) that the box will
- indeed break any American code. Russian and Soviet codes, he says, are
- different. "Our top codes are entirely different from yours," he says.
-
- So -- as I've come to expect from Hollywood, most of the technical
- details in the book (and I assume the movie), are either impractical,
- impossible, or nonexistent. (There are a few neat tricks shown, however.)
- But let's assume someone does figure out how to trivially factor very
- large numbers. I understand that would defeat RSA. Am I correct? How about
- DES? Are other common government and commercial cryptosystems based on
- large primes? I assume that one-time pads would still be quite effective.
-
- And how about this "Russian codes are different" stuff? Any truth to this?
- I understand one can buy source code for DES and RSA on the streets of
- Leningrad (according to Communications of the ACM).
-
- Someday someone will produce a computer-cracking scene in a movie that
- looks as if the people involved have logged in to a system via a modem
- at least once in their lives. I don't think "Sneakers" will be it.

- P.S. If no one agrees that the technical details in this movie are silly,
- I'd be glad to post more.
