An interesting read, but poorly titled, either by the author or by their editors: The article isn't exclusively about cryptology, but about the broader field of SIGINT/COMINT.<p>Two examples of non-crypto trends cited in the article: The increasing use of VHF by Chinese and North Korean forces, complicating intercept (VHF intercept has to be line of sight) and the near-complete ignorance of traffic analysis and of analysis of Chinese supply management, e.g., that they were ordering large quantities of maps of Korea, etc.<p>The allies had the data to tell them the Chinese were preparing, e.g., presence of Chinese prisoners captured by ROK forces, but dismissed much of it.<p>None of the above is cryptology.
Can anybody figure out a date for this?<p>We changed the url from <a href="http://www.foia.cia.gov/sites/default/files/DOC_0000872751.pdf" rel="nofollow">http://www.foia.cia.gov/sites/default/files/DOC_0000872751.p...</a>, which has redactions.
