STRATEGIC PLAN Funding in the US (Circa 1980) MANAGING RISK to ENSURE INTELLIGENCE ADVANTAGE
Intelligence Reform And Terrorism Prevention Act of 2004 FY2016-2020 IC S&T Executive Order 12333 (1981) Industrial R&D Funding Begins Exceeding Government R&D STRATEGIC PLAN Funding in the US (Circa 1980) MANAGING RISK TO ENSURE INTELLIGENCE ADVANTAGE National Security Act of 1947 Office of Strategic Services Disbanded (1945) 1 About the Cover: The cover uses a red and blue double helix to represent multiple concepts relating to the Intelligence Community’s (IC’s) science and technology (S&T) efforts. For example, starting at the bottom and moving up the image on the cover one observes—in chronological order—a number of key “red” challenges and “blue” technological achievements in the history of the IC. The use of this construct was not chosen randomly, however. Akin to how the base pairs in strands of deoxyribonucleic acid (DNA) correspond to one another, researchers and technologists within the IC S&T enterprise aspire to create capabilities that link to the threat environment of today—and in the future. Lastly, and perhaps most importantly, the choice of a DNA strand is meant to convey the critical importance of basic research to the IC’s mission.

THE MASS SURRENDER OF GERMAN TROOPS TO THE 347th INFANTRY REGIMENT ON MAY 6, 1945 By Tom Stafford, L-347 In coordination with Ray Miles, I-347 John McAuliffe, M-347 Lew Goad, L-347 Contents Prologue.......................................................................................................3 The Capture of Plauen.................................................................................6 East Meets West - The Movement Toward Czechoslovakia........................9 An Unforgettable Procession .....................................................................17 The Journey Home, Then Onto Japan ........................................................32 Appendix ....................................................................................................37 About the Author ........................................................................................39 2 Prologue Earlier this year, while reviewing the 87th Infantry Division's history on the Internet, I was surprised to read that our Division is credited with capturing only 10,282 German Prisoners of War during World War II. Having been personally involved in the acceptance on May 6, 1945 of the formal surrender of over 40,000 Wehrmacht (German Regular Army) and Schutzstaffel (SS) troops1, including a considerable number of high ranking general officers -- a day before the Unconditional Surrender of all German Forces was signed and three days before active operations were ordered to cease -- I contacted John “Mac” McAuliffe2 to determine if he had any information regarding what I consider to be an obvious discrepancy in our Division's history. It is interesting to note that a review of the official records contained in the National Archives pertaining to our Division, particularly those of the 347th Infantry and its 3rd Battalion, clearly reveal that a number of these surrendering Wehrmacht and SS troops began to enter our lines on May 7, two days before ALL active operations were to cease at 001B, 9 May, 1945 between the Germans and the Allied Expeditionary Forces (AEF). -
The Croix De Guerre Was Awarded for Bravery to Military Personnel and Recipients of the Légion D'honneur and Médaille Militaire
During World War I, the Croix de Guerre was awarded for bravery to military personnel and recipients of the Légion d'Honneur and Médaille Militaire. This decoration was established by the French Republic in 1915 and is awarded to soldiers, airmen or sailors or all ranks, officers included, and also to officers and men of Allied forces, mentioned in French Despatches, for an individual feat of arms mentioned in a Despatch from the general officer commanding an Army, Army Corps, Division, Brigade or the C.O. of a regiment or the corresponding unit of Naval forces. The different classes of despatches for which a recipient was awarded the cross may be recognized by the following emblems on the ribbon: Army Despatch - small bronze laurel branch (Palme en bronze); Army Corps Despatch - silver gilt star; Divisional Despatch - silver star; Brigade, Regimental or similar Unit Despatch - bronze star. Every mention is represented by its emblem, thus a man can wear the cross with a silver star and a bronze palm. For every five bronze palms he gets instead a silver palm. The award of the Légion d'Honneur carries with it a Croix de Guerre avec Palme. The ribbon is green ribbed with black and has seven red stripes. For bravery in the face of the enemy. It can be awarded more than once. Subsequent awards are denoted by bronze, silver, and gold insignia worn on the ribbon. In WW1, US Army personnel who were awarded the MOH also received the Croix de Guerre, avec palme, for the same action. The Fourragere, in the colors of the Croix de Guerre, representing two unit citations in the Orders of the Army, is authorized to be worn by all active members of the 9th Regiment. -

8 THE POLISH TRACE COMPOSED FROM COMMONLY AVAILABLE SOURCES BY LECH POLKOWSKI FOR IJCRS2017 FOREWORD It is a desire of many participants of conferences to learn as much as possible about the history and culture of he visited country and place and organizers try to satisfy this desire by providing excursions into attractive places and sites. IJCRS2017 also tries to take participants to historic sites of Warmia and Mazury and to show elements of local culture. As an innovation, we propose a booklet showing some achievements of Polish scientists and cryptographers, no doubt many of them are known universally, but some probably not. What bounds all personages described here is that they all suffered due to world wars, th efirst and the second. These wars ruined their homes, made them refugees and exiles, destroyed their archives and libraries, they lost many colleagues, friends and students but were lucky enough to save lives and in some cases to begin the career overseas. We begin with the person of Jan Czochralski, world famous metallurgist, discoverer of the technique of producing metal monocrystals `the Czochralski methode’ and inventor of duraluminum and the `bahnalloy’ who started his career and obtained its heights in Germany, later returned to Poland, became a professor at the Warsaw Polytechnical, played an important role in cultural life of Warsaw, lived in Warsaw through the second world war and the Warsaw Uprising of August-September 1944 and after the war was accused of cooperating ith occupying German forces and though judged innocent was literally erased from the public life and any information about him obliterated. -

Pioneers in U.S. Cryptology Ii
PIONEERS IN U.S. CRYPTOLOGY II This brochure was produced by the Center for Cryptologic History Herbert 0. Yardley 2 Herbert 0. Yardley Herbert 0 . Yardley was born in 1889 in Worthington, Indiana. After working as a railroad telegrapher and spending a year taking an English course at the University of Chicago, he became a code clerk for the Department of State. In June 1917, Yardley received a commission in the Signal Officers Reserve Corps; in July Colonel Ralph Van Deman appointed him chief of the new cryptanalytic unit, MI-8, in the Military Intelligence division. MI-8, or the Cipher Bureau, consisted of Yardley and two clerks. At MI-8's peak in November 1918, Yardley had 18 officers, 24 civilians, and 109 typists. The section had expanded to include secret inks, code and cipher compilation, communications, and shorthand. This was the first formally organized cryptanalytic unit in the history of the U.S. government. When World War I ended, the Army was considering disbanding MI-8. Yardley presented a persuasive argument for retaining it for peacetime use. His plan called for the permanent retention of a code and cipher organization funded jointly by the State and War Departments. He demonstrated that in the past eighteen months MI-8 had read almost 11,000 messages in 579 cryptographic systems. This was in addition to everything that had been examined in connection with postal censorship. On 17 May Acting Secretary of State Frank L. Polk approved the plan, and two days later the Army Chief of Staff, General Peyton C. -
A Counterintelligence Reader, Volume 2 Chapter 1, CI in World
CI in World War II 113 CHAPTER 1 Counterintelligence In World War II Introduction President Franklin Roosevelts confidential directive, issued on 26 June 1939, established lines of responsibility for domestic counterintelligence, but failed to clearly define areas of accountability for overseas counterintelligence operations" The pressing need for a decision in this field grew more evident in the early months of 1940" This resulted in consultations between the President, FBI Director J" Edgar Hoover, Director of Army Intelligence Sherman Miles, Director of Naval Intelligence Rear Admiral W"S" Anderson, and Assistant Secretary of State Adolf A" Berle" Following these discussions, Berle issued a report, which expressed the Presidents wish that the FBI assume the responsibility for foreign intelligence matters in the Western Hemisphere, with the existing military and naval intelligence branches covering the rest of the world as the necessity arose" With this decision of authority, the three agencies worked out the details of an agreement, which, roughly, charged the Navy with the responsibility for intelligence coverage in the Pacific" The Army was entrusted with the coverage in Europe, Africa, and the Canal Zone" The FBI was given the responsibility for the Western Hemisphere, including Canada and Central and South America, except Panama" The meetings in this formative period led to a proposal for the organization within the FBI of a Special Intelligence Service (SIS) for overseas operations" Agreement was reached that the SIS would act -
Polish Mathematicians Finding Patterns in Enigma Messages
Fall 2006 Chris Christensen MAT/CSC 483 Machine Ciphers Polyalphabetic ciphers are good ways to destroy the usefulness of frequency analysis. Implementation can be a problem, however. The key to a polyalphabetic cipher specifies the order of the ciphers that will be used during encryption. Ideally there would be as many ciphers as there are letters in the plaintext message and the ordering of the ciphers would be random – an one-time pad. More commonly, some rotation among a small number of ciphers is prescribed. But, rotating among a small number of ciphers leads to a period, which a cryptanalyst can exploit. Rotating among a “large” number of ciphers might work, but that is hard to do by hand – there is a high probability of encryption errors. Maybe, a machine. During World War II, all the Allied and Axis countries used machine ciphers. The United States had SIGABA, Britain had TypeX, Japan had “Purple,” and Germany (and Italy) had Enigma. SIGABA http://en.wikipedia.org/wiki/SIGABA 1 A TypeX machine at Bletchley Park. 2 From the 1920s until the 1970s, cryptology was dominated by machine ciphers. What the machine ciphers typically did was provide a mechanical way to rotate among a large number of ciphers. The rotation was not random, but the large number of ciphers that were available could prevent depth from occurring within messages and (if the machines were used properly) among messages. We will examine Enigma, which was broken by Polish mathematicians in the 1930s and by the British during World War II. The Japanese Purple machine, which was used to transmit diplomatic messages, was broken by William Friedman’s cryptanalysts.
