Yes, I know you're smiling - expecting something funny to come next. Think again. They key to computer security is randomness, something that computers find hard to achieve. Cloudflare is an international company that uses lava lamps, among other techniques, to create encryption. Lots on YouTube.

COOL I can give you away to create an encryption key that is impossible to break.

It wouldn't take much to stump me.

Not impossible. It would just take longer and a lot more computer power.

Way back in 1970 in my computer systems programming class one of the challenges given to us was to create a true random number generator. Fairly easy to get ALMOST there...

Saw an interesting program on PBS on a similar subject. Encryption experts sometimes use the sum of the square of two prime numbers as a base. It's nearly impossible to find the two original primes.

I remember seeing a TV show as a kid, and one character explained to another where they got the numbers for the numbers racket. It had something to do with the treasury figures published in the papers every day.

My Mother played this numbers game for a quarter (25 cents) a shot back in the 1940’s.
She would pick three numbers. If they matched some specific numbers published in the paper, she was a winner! I think the odds were about 100 to 1.
The bookie would come by each week to collect the bets and pay last week’s winners.
She never won!
It was a very transparent operation as the players nor the bookie had any control over the numbers published in the paper by the Federal government for all to see.
BTW- The bookie drove a Cadillac and wore a ‘Zoot Suit’ with a wide brim Fedora !

And that's why they called the "The Good Old Days."

Yes I mean IMPOSSIBLE! you could take the most baddest fasted computer and they would not be able to break the code, ain't no way no how. Ask me how I know.

Hey, my 6 lava lamps in storage, might be worth something after all!

will

I have only one lava lamp, but it doesn't work very well with the LED bulb.

Well if the random numbers are used as a ‘one time pad’ then it is impossible to break.

I read an article recently, can't remember where, that stated that a special chip or app had been developed which somehow used a rolling code, much like that used for automobile security fobs or for garage door openers, for use in computers to add security. According to the article, a team of several hackers spent three months trying to break into computers with the device and were unsuccessful. Wish I could find it again.

I think this is the story you referred to
