On July 29, 2010, Public Intelligence received a notice from Paul Malcolm of Booz Allen Hamilton in support of the U.S. Air Force Key Management Infrastructure program. Mr. Malcolm is very polite in requesting the removal of two “For Official Use Only” documents, one of which, he says, is proprietary. Both documents concern the Simple Key Loader, a fill device used to load cryptographic keys into encryption systems. The first document is the U.S. Air Force SKL Wireless & Black Data Distribution System Overview. The second is the Simple Key Loader Instruction Guide. Neither of the documents bear any particular markings indicating their proprietary nature. While he does not specify which document is proprietary, it is possible that the SKL Instruction Guide is thought to be proprietary because it concerns the functioning and operation of a device produced under contract and ostensibly owned by the Sierra Nevada Corporation. In fact, it is from the official website of the Sierra Nevada Corporation that both of these documents were originally and inadvertently made available. One is still available.
