Letting the cat out of the bag...

In 1977, a year after the Other-1 was functional, working as a systems programmer, I read the following surprising and exciting article in my favorite magazine:
Martin Gardner, in his Mathematical Games column for Scientific American, August 1977, gave a technical description of the "trapdoor" algorithm involving factorization of large primes developed by MIT computer scientists Ronald Rivest, Adi Shamir, and Leonard Adleman, thus making viable Diffe-Hellman based Public-Key Cryptosystems public knowledge. The column was modified slightly for inclusion as a book chapter, available here, courtesy of the Mathematical Association of America:

Book excerpt: Penrose Tiles To Trapdoor Ciphers ...and the Return of Dr. Matrix, By Martin Gardner, Rev 1997, Chapters 13, 14.

Since then...
Professor Rivest's speaker Slide Set "On the Growth of Cryptography" (updated 2016).

Homebuilt CPUs WebRing

Join the ring?

To join the Homebuilt CPUs ring, drop me (Dave Brooks) a line, mentioning your page's URL. I'll then add it to the list.
You will need to copy this code fragment into your page.
Note: The ring is chartered for projects that include a home-built CPU. It can emulate a commercial part, that′s OK. But actually using that commercial CPU doesn′t rate. Likewise, the project must have been at least partially built: pure paper designs don′t rate either. It can be built using any technology you like, from relays to FPGAs.
