- Dear B:
- I know you love to play with simulations of large cellular automata,
- particularly Conway's beautiful game of life. Here is a file of
- initialization data for an NxN automation. Enjoy. Yours, A.
-
- Life is a nice example - I was trying to think of uses like GIFs or music,
- but it's pretty obvious when data sounds/looks like white noise.
- But life could work; fractals are another possibility,
- especially if your fractal-generator feeds off random input.
- "My fractal program produced this ugly random-looking output -- is it a bug?"

- .... illegally encrypted data, since A is presumed innocent.
- To do this they will have to decypher A's message.
- Perhaps they cannot, because they cannot break DES. Even worse,
- perhaps they can break DES, but they do not want to reveal this in court.
-
- It's relatively easy to get around the latter problem - they can claim
- they were doing a brute-force or guessing search, and it guessed right.
- Tough to do if your key is largely non-ASCII, but highly plausible for
- short ASCII keys. Or they can say they got an anonymous tip ....
