Don't miss a single story I would like to receive the following emails: Have a breaking story? By using bit keys, Randy and Avi could keep their communications secret from nearly every entity in the world for at least the next several years.

A bit key would be vastly, astronomically more difficult to break. Some people go so far as to use keys or even bits in length. These will stop the very best codebreakers on the face of the earth for astronomical periods of time, barring the invention of otherworldly technologies such as quantum computers. He is not bothering to look at the screen; he is staring out the window at the lights on the trucks and the jeepneys. He is only using one hand, just flailing away loosely at the keyboard.

Whenever he strikes a key, Ordo uses that clock to record the current time, down to microseconds. He hits a key at Ordo keeps track of all of these intervals and discards the more significant digits in this example the. It wants a whole lot of random numbers, and it wants them to be very, very random. It is taking somewhat random numbers and feeding them through hash functions that make them even more random. It is running statistical routines on the results to make sure that they contain no hidden patterns.

It has breathtakingly high standards for randomness, and it will not stop asking Randy to whack on the keyboard until those standards are met. The longer the key you are trying to generate, the longer this takes.

Randy is trying to generate one that is ridiculously long. He has pointed out to Avi, in an encrypted e-mail message, that if every particle of matter in the universe could be used to construct one single cosmic supercomputer, and this computer was put to work trying to break a bit encryption key, it would take longer than the lifespan of the universe.

But what about quantum computers? And what if new mathematical techniques are developed that can simplify the factoring of large numbers? It is still hanging in front of his eyes, like the afterimage of a strobe: Randy rests his tired hand. Ordo politely warns him that it may be busy for a while, and then goes to work. It is searching the cosmos of pure numbers, looking for two big primes that can be multiplied by each other to produce a number bits long.

If you want your secrets to remain secret past the end of your life expectancy, then, in order to choose a key length, you have to be a futurist. You have to anticipate how much faster computers will get during this time. You must also be a student of politics. Because if the entire world were to become a police state obsessed with recovering old secrets, then vast resources might be thrown at the problem of factoring large composite numbers.

So the length of the key that you use is, in and of itself, a code of sorts. This can be ruled out with a bit of research into his past accomplishments. This can also be ruled out with some research. Randy paces around his room while his computer soars through number space The early adopters though probably weren't in it simply for monetary gain, they're probably all for spreading it around, stabilizing it, then add legitimacy and worth to their wallets.

The more people involved the better. Besides dumping a ton at once is stupid when you're selling the last chunk of your lot for dimes and nickels. Holliday on April 30, ,
