What about time locking the file so that it can't be opened until a certain time?
not possible.
We can try naming the file PLEASE DONT OPEN UNTIL "THIS" TIME.
I think the issue with a suggestion like this isn't "not possible", it's more about "maybe possible, but more trouble than it's probably worth, while only covering a limited range of side-channel attacks".not possible.
maybe possible
Well, you could make decoding rely on a passcode transmitted by internet/phone at a specified time. You could build a special computer with a secure timer that doesn't decrypt / release the key until a specified time.I'd like to hear how you think so. I can't think of a way that it could be implemented without being vulnerable to attack.
I was looking for something that wasn't essentially the same as Stefan's idea.
Morse code. Delegates get special training in decoding it. On the day of, a trooper is dropped from plane into the competiton with radio equipment. The WCA then sends the encrypted scrambles to the delegate via radio contact. Solution found?
On topic: Electricdoodles idea requires too much internet, which most competitons won't have access to.
How are delegates chosen in the first place? I don't see it in the regulations on how that is decided. Is it just a "that guy is trustworthy since he's done x and y" decision or do the top WCA officials have something written up?
