Schneier - A New Clue for the Kryptos Sculpture

Jim Sanborn, who designed the Kryptos sculpture in a CIA courtyard, has released another clue to the still-unsolved part 4. I think he's getting tired of waiting.

Did we mention Mr. Sanborn is 74?

Holding on to one of the world's most enticing secrets can be stressful. Some would-be codebreakers have appeared at his home.

Many felt they had solved the puzzle, and wanted to check with Mr. Sanborn. Sometimes forcefully. Sometimes, in person.

Elonka Dunin, a game developer and consultant who has created a rich page of background information on the sculpture and oversees the best known online community of thousands of Kryptos fans, said that some who contact her (sometimes also at home) are obsessive and appear to have tipped into mental illness. "I am always gentle to them and do my best to listen to them," she said.

Mr. Sanborn has set up systems to allow people to check their proposed solutions without having to contact him directly. The most recent incarnation is an email-based process with a fee of $50 to submit a potential solution. He receives regular inquiries, so far none of them successful.

The ongoing process is exhausting, he said, adding "It's not something I thought I would be doing 30 years on."
