How about any process where the state and the change between one state and another state can be described tolerably simply in some language that is not explicitly algorithmic, but which is enormously difficult, complex, and expensive to describe in explicitly algorithmic language, for example water pouring through a channel? -- --------------------------------------------------------------------- We have the right to defend ourselves and our property, because of the kind of animals that we James A.

CYPHERPUNKS TO THE RESCUE
by Sandy Sandfort 17 Dec '03

17 Dec '03

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ SANDY SANDFORT . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . C'punks, On the noon news in San Francisco, there was an item of crypto interest. It was about something I think they called the "Code Grabber." It is a device which receives and records the coded RF signals used to remotely unlock car and garage doors. The hand-held unit is a little larger than a paperback book. It has a half dozen switches on it. After you intercept someone's code, you can play it back anytime to control that person's car lock or garage door. It's kind of like a TV universal remote. Some politicos have already started talking about banning it, but I think just the publicity will guarantee a healthy black market in such devices. The public will be clamoring for a solution. Enter the Cypherpunks. How can this nifty burglary tool be outsmarted? How about a replacement system that uses strong crypto? The Code Grabber represents a great opportunity for an inventive Cypherpunk to make some money AND promote crypto awareness. The questions are: Could standard auto and garage door openers easily be retrofitted? Could a "crypto remote" with its own CPU be made small enough to fit into a hand-held unit? Could such a system be made for a reasonable cost? S a n d y P.S. I bet there are some other interesting uses to which such a device could put. Any ideas? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

How about a quote from Vernor Vinge's "True Names" (a must read for any cypherpunk, happily now back in print): "Like most folks, honest citizens or warlocks, he had no trust for the government standard encryption routines, but preferred the schemes that had leaked out of academia -- over the NSA's petulant objections -- over the last fifteen years". This from a book that was published in 1981. Marshall Clow Aladdin Systems mclow(a)san_marcos.csusm.edu

In other words, both correspondents must comply with gov't key > surrender, or neither. It's a little better than that, but not much. There are three sides to the process - writing the wiretap field, verifying the wiretap field, and using the field to wiretap. The receiver can definitely verify the wiretap field, but has a choice about whether to do the verification or accept conversations with an invalid field. If a conformist receiver refuses to accept conversations without a verified wiretap field, the sender has to include it to talk. (This is the opposite of Clipper, where the receiver has no control over the system, but the sender can construct a fake wiretap block with some work.) The sender has a choice of what keymaster agencies to use, but the receiver can choose whether or not those agencies are acceptable. It's easy to turn off software key escrow, but only on your own machines. Unfortunately, the most interesting cases are applications like cellphones, where the sender is the occasionally non-conformist phone user, the receiver is the phone company, and the government can bully the phone company into being conformist about both verifying the block and only accepting politically correct keymasters. For other cases, like encrypting fax machines, they'll probably accept any keymaster, so you can probably use "Dev Null Key Security Inc." (The government *could* get nasty and insist that encrypting fax machines can only be imported if they verify that the keymaster's key is signed by the Key Generation Bureau, but it's a lot harder to control millions of fax machine users than a few hundred phone companies.)
