Thomas Jefferson's cipher message from Robert Patterson For more than 200 years, buried deep within Thomas Jefferson's correspondence and papers, there lay a mysterious cipher -- a coded message that appears to have remained unsolved. Until now.... To Mr. Patterson's view, a perfect code had four properties: It should be adaptable to all languages; it should be simple to learn and memorize; it should be easy to write and to read; and most important of all, "it should be absolutely inscrutable to all unacquainted with the particular key or secret for decyphering."

You've probably heard of the WWII Navajo "code talkers"
who managed to baffle crack Japanese cryptanalysts and were credited with enabling US success at Iwo Jima. Civil engineer, journalist and photographer Philip Johnston
was the determined mind behind the "windtalkers". The son of missionaries, Johnston grew up on a Navajo reservation and was one of only a handful of outsiders fluent in the Navajo language. A bit of his background is included this article
, and you can read a complete history
of his plan, view an archive of photos by Johnston
, and see copies of his enlistment application
letter to the Marine Corps commandant, as well as a recommendation letter
from the Commanding General. (more inside...)

The Key Vanishes: Scientist Outlines Unbreakable Code [NEW YORK TIMES - free reg required] In essence, the researcher, Dr. Michael Rabin and his Ph.D. student Yan Zong Bing, have discovered a way to make a code based on a key that vanishes even as it is used. While they are not the first to have thought of such an idea, Dr. Rabin says that never before has anyone been able to make it both workable and to prove mathematically that the code cannot be broken.
Once this gets out, the debate on exporting strong crypto would seem to be essentially over.
