NSA released on 23 July 2013 "The History of Traffic Analysis: World War I-Vietnam." http://www.nsa.gov/about/_files/cryptologic_heritage/publications/misc/traffic_analysis.pdf It notes the formation of T/A (Traffic Analysis) and C/A (Cryptanalysis) as the two elements of code-breaking, using the mail analogy of T/A for the envelope, C/A for the contents. As noted elsewhere T/A is now publicized as "metadata." ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://ativel.com http://postbiota.org AC894EC5: 38A5 5F46 A4FF 59B8 336B 47EE F46E 3489 AC89 4EC5 -- Too many emails?
