TO MY WIFE LOIS Prologue For years I had wondered what the last day would be like. In January 1976 after two decades in the top echelons of the British Security Service, MI5, it was time to rejoin the real world. I emerged for the final time from Euston Road tube station. The winter sun shone brightly as I made my way down Gower Street toward Trafalgar Square. Fifty yards on I turned into the unmarked entrance to an anonymous office block. Tucked between an art college and a hospital stood the unlikely headquarters of British Counterespionage. I showed my pass to the policeman standing discreetly in the reception alcove and took one of the specially programmed lifts which carry senior officers to the sixth-floor inner sanctum. I walked silently down the corridor to my room next to the Director-General's suite. The offices were quiet. Far below I could hear the rumble of tube trains carrying commuters to the West End. I unlocked my door. In front of me stood the essential tools of the intelligence officer’s trade - a desk, two telephones, one scrambled for outside calls, and to one side a large green metal safe with an oversized combination lock on the front. -
A Rumour Exists Among Cambridge Students
A rumour exists among Cambridge students – that they may be discretely and mysteriously tapped on the shoulder during their time there, meaning they have been invited to become a spy. It’s difficult to determine if this is still true; presumably the new spies would be too secretive to let it slip. But many students live in hope for the day they will become the next James Bond. Cambridge has a long-running association with secret intelligence, which has helped, and hindered, Britain through times of war and peace. Reach Cambridge students live and learn in the same university that has been home to many infamous spies – not bad for a residential summer school! We’ll take a look at some of the most famous spies associated with the city. Christopher Marlowe Marlowe is more widely known as a famous playwright, with some suggesting that he is the true author of Shakespeare’s plays. He studied at Corpus Christi College, Cambridge, and it is alleged that it was during this time that he was recruited to be a spy. Elizabeth I presided over the first British Secret Services, used during her reign to gather intelligence against Catholics. Some evidence that Marlowe was involved in these activities is that he left Cambridge for long stretches of time that the university would usually not allow, and when he was in college, he bought much more food and drink than he would have been able to afford on his scholarship money alone. It was apparently the extra money he earned from being a government spy throughout his life which supplemented his income, allowing him to continue writing. -
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. -
A Killing That Shook the KGB the EARLY Years of the Gorbachev Era Saw a Change in the KGB's Attitude to Terrorism
How Moscow supported assassinations overseas until Gorbachev came to power A killing that shook the KGB THE EARLY years of the Gorbachev era saw a change in the KGB's attitude to terrorism. Moscow's growing distaste for some of its Third World terrorist associates was particu- larly evident in the case of Colonel Gadaffi. The turning point in that relationship was the demonstration outside the Libyan "Peo- ple's Bureau" in London in April 1984 when Death that disenchanted Moscow: WPC Fletcher and a tribute where she was killed a Libyan intelligence man opened fire and killed WPC Yvonne Fletcher. which refused to have them followed up. were attacking him in the western media.

Box 1346 Ann Arbor, Ml 48106-1346 2 ABSTRACT Churchill's interest in secret signals intelligence (sigint) is now common knowledge, but his use of intercepted diplomatic telegrams (bjs) in World War Two has only become apparent with the release in 1994 of his regular supply of Ultra, the DIR/C Archive. Churchill proves to have been a voracious reader of diplomatic intercepts from 1941-44, and used them as part of his communication with the Foreign Office. This thesis establishes the value of these intercepts (particularly those Turkey- sourced) in supplying Churchill and the Foreign Office with authentic information on neutrals' response to the war in Europe, and analyses the way Churchill used them. -

Agnes Meyer Driscoll Vs. the Enigma and the Bombe Colin Burke
Colin Burke 1-2001 © Agnes Meyer Driscoll vs. the Enigma and the Bombe Colin Burke ABSTRACT: Documents in Britain‘s National Archives/ Public Record Office and in the U.S. National Archive‘s Record Groups RG457 and RG38 indicate that in mid-1941 the United States Navy‘s codebreaking organization, OP-20-G ignored an opportunity to gain full knowledge of Britain‘s anti-Enigma methods and machines. Spending a year and one-half working on what it felt was a unique and much more effective method– but one that failed--OP-20-G‘s, staff, at a critical time in U.S.- British relations ,did not inform America‘s decision makers of Britain‘s willingness to share its crypto-secrets . As a result, American leaders believed that England‘s GC&CS had deliberately withheld vital information that would have allowed the development of an independent American attack on Naval Enigma. That belief lasted Colin Burke 1-2001 © throughout the war and caused friction between the two nations. Other consequences of OP-20-G‘s mid-1941 decision were to delay the adoption of the British Bombe and its allied methods and to waste perhaps six months of the vital time of the new team of cryptanalysts and engineers assigned, in early 1942, to develop an American Bombe.

Gendering Decryption - Decrypting Gender
1 Gendering decryption - decrypting gender The gender discourse of labour at Bletchley Park 1939-1945 Photograph taken from Smith 2011. Spring 2013 MA thesis (30 hp) Author: Annie Burman Supervisor: Mikael Byström Seminar leader: Torkel Jansson Date of seminar: 4 June 2013 2 Abstract Ever since the British efforts to break Axis codes and ciphers during the Second World War were declassified in the 1970s, the subject of Government Code and Cipher School, the organisation responsible, Bletchley Park, its wartime headquarters, and the impact of the intelligence on the war has fascinated both historians and the general public. However, little attention has been paid to Bletchley Park as a war station where three-quarters of the personnel was female. The purpose of this thesis is to explore the gender discourse of labour at Bletchley Park and how it relates to the wider context of wartime Britain. This is done through the theoretical concepts of gendering (the assignation of a gender to a job, task or object), horizontal gender segregation (the custom of assigning men and women different jobs) and vertical gender segregation (the state where men hold more prestigious positions in the hierarchy than women). The primary sources are interviews, letters and memoirs by female veterans of Bletchley Park, kept in Bletchley Park Trust Archive and the Imperial War Museum’s collections, and printed accounts, in total two monographs and five articles. Surviving official documents from Bletchley Park, now kept in the National Archives, are also utilised. Using accounts created by female veterans themselves as the main source material allows for women’s perspectives to be acknowledged and examined.
