Christos military and intelligence corner: Overview of 2017

2017 turned out to be a very productive year. During 2017 I copied material from government archives in Germany, US and UK, I received a lot of material from the NSA’s freedom of information act office and I also benefitted from the release of interesting files that were uploaded to the NSA and CIA FOIA websites.

Some of my friends also shared important reports with me and I did my best to repay them by giving them some of my material.

1). Regarding original essays, I wrote the following:

The compromise of the Croat Enigma K cipher machine by the German Army’s codebreakers

The Japanese TOKI diplomatic cipher 1943-45

The Abwehr’s Enigma G cipher machine and Procedure 63

The compromise of Greek partisan radio communications in WWII

Cipher machines of WWII

Secure ciphers - Insecure messages

Information on the Enigma cipher machine found in the War Diary of Inspectorate 7/VI

Signals intelligence and codebreaking operations during the Greek-Italian War of 1940-41
