Concept of a
cryptanalytical attack where special brute-force chips are inserted to every TV and radio sold in China. Each chip is either set to test a
specific array of keys or just
random keys. Now when the
government needs a code broken, they broadcast the
cipher text and every chip begins processing away. When one of the chips finally stumbles upon the key, it alerts its owner by prompting them that they have won the lottery and must call a phone number and give them a '
special code' to redeem their prize. The prize would encourage good citizenship.
As of 1995, there are roughly 740 million televisions and radios in the United States (out numbering people 5:14!) If each device tested a million keys per second, a 64-bit key could be cracked in 20 hours, or 28 hours if the chips were testing random numbers.
The obvious benefits are that someone else is fronting the bill for your project, hardware and electricity. This would also encourage the sales of televisions and radios
Note: China was selected because if every citizen was outfitted with a device, they could throw a lot of computational power at the problem. The numbers are from Applied Cryptography (pg157), which got said numbers from the 1995 World Almanac and Book of Facts
