Read Isaac Asimov's Foundation series!!!

Another potential real-world application is that of truly secure communications. I've read about the possibilities of using chaos in encryption systems. As processors get faster and more powerful, the ability to break 128-bit encryption (or even higher levels) becomes easier. The limiting factor now is time. Well, you say, once someone breaks 128-bit encryption, simply move to 256, 512, or 1024 ... it gets exponentially harder to break. Ahh, but the problem with this is that it takes more time and computational power just to use higher encryptions like this. The plus of chaos is that it should supposedly keep down the overhead for authorized users, while being maintaining a very high security level.
