~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
