NASA Using 1960s Cryptanalysis Techniques
Well, sort of.
This paper from the Goddard Space Center, “NiCd Space Battery Test Data Analysis Project, Phase 2 Quarterly Report, 1 Jan. – 30 Apr. 1967,” uses “cryptanalytic techniques” — some sort of tri-gram frequency analysis, I think — to ferret out hidden clues about battery failures.
It’s hard to imagine non-NSA cryptography in the U.S. from the 1960s. Basically, it was all alphabetic stuff. Even rotor machines were highly classified, and absolutely nothing was being done in binary.
