National Security Agency gives rare insight into their inner workings

NSA Design Patent

This weeks I stumbled across what seemed like a very old-fashioned design for a slide rule. Curious, who would seek patent protection for something seemingly outdated, I found – our government. More specifically, the super-secret National Security Agency.

Seems the NSA provides a rare glimpse into their inner workings. It appears the agency that otherwise deals with breaking sophisticated cipher codes has a heart for good old technology. But then: ┬áKeeping secrets is still in their blood: ┬áThe original design patent application was filed with a non-publication request, even though design patents don’t publish before issue anyway. Probably just to make sure.

Wonder what slide rule they use to read AES encrypted messages…
