NCMF and the NSA Center for Cryptologic History (CCH)

Gen. Michael Hayden, 2003 NSA Director

The Foundation assists the NSA Center for Cryptologic History (CCH) in preparing for the biennial Symposium on Cryptologic History and provides support to the CCH History Research Program. In 2003, then DIRNSA, General Michael V. Hayden, requested support from the NCMF for the 2003 Symposium. Since then the Foundation and CCH have teamed up to stage a unique biennial event that attracts international attention from academia and the Intelligence Community.

Upcoming Symposium on Cryptologic History - October 2017

The next biennial Symposium on Cryptologic History will take place October 19 - 20, 2017 at the Johns Hopkins Applied Physics Laboratory's Kossiakoff Center in Laurel, Maryland. Following the Symposium, on Saturday, October 21, participants will be given an opportunity to tour the National Cryptologic Museum and participate in a workshop on sources for research in cryptologic history, as well as a presentation about William and Elizebeth Friedman.

The theme for the 2017 Symposium is "Milestones, Memories, and Momentum." There are many milestones to mark in 2017: the 160th anniversary of the first attempt to span the Atlantic with a telegraph cable, 100 years since both the entry of the United States into World War I and the Russian October Revolution, and 75 years after the World War II battles of Coral Sea and Midway. The Symposium will take place just a few months before the 50th anniversary of the Tet Offensive in Vietnam, and during the 25th year after the fall of the Soviet Union and the end of the Cold War.

Previous CCH Symposiums

The theme for the 2015 Symposium was “A Century of Cryptology.” As we mark the centenary years of World War I (1914–1918), when so many significant advancements occurred in the field of cryptology, we examine the impact cryptologists made throughout the twentieth century, especially during such periods as World War II, the Cold War, the Korean War, the War in Vietnam, and the post-Cold War era. The Symposium included panels that look at the foundations of cryptology before the “Great War.”

Mr. Chris Inglis, Deputy Director NSA in 2013

The theme for the 2013 Symposium was "Technologic Change and Cryptography:  Meeting the Historical Challenge." The keynote address was given by Mr. Chris Inglis, then Deputy Director of NSA. Present at the Symposium were scholars from around the world and the presentations were wide ranging. Examples include: Intelligence Preparation for the Next War, Cipher Systems and Methods, Cryptology as Musical Entertainment, Cryptology in the Ancient World, Bletchley Park Celebrated, and COMINT and the Civil War.
