90-Year-Old Cryptanalytic Efforts Must Stay Secret, Says NSA
August 9th, 2016Via: The National Security Archive:
The National Security Agency is withholding 90-year-old information on early American cryptanalytic efforts against Russia and the Soviet Union from a 20-year-old document on the grounds that releasing the information could “reasonably be expected to cause identifiable or describable damage to national security.”
Specifically, the NSA claims that the release of the information would harm another government agency’s (OGA) “intelligence activities (including covert action), intelligence sources or methods, or cryptology” – the OGA cited by the NSA is either the Defense Intelligence Agency (DIA) or the CIA.
