Cryptography in a Quantum World
Cryptography in a Quantum World ⋆ Gilles Brassard 1,2 1 D´epartement d’informatique et de recherche op´erationnelle Universit´ede Montr´eal, C.P. 6128, Succursale Centre-ville Montr´eal (QC), H3C 3J7 Canada 2 Canadian Institute for Advanced Research [email protected] http://www.iro.umontreal.ca/~brassard/en/ Abstract. Although practised as an art and science for ages, cryptog- raphy had to wait until the mid-twentieth century before Claude Shannon gave it a strong mathematical foundation. However, Shannon’s approach was rooted is his own information theory, itself inspired by the classical physics of Newton and Einstein. But our world is ruled by the laws of quantum mechanics. When quantum-mechanical phenomena are taken into account, new vistas open up both for codemakers and codebreakers. Is quantum mechanics a blessing or a curse for the protection of privacy? As we shall see, the jury is still out! Keywords: Cryptography, Quantum mechanics, Quantum computa- tion, Post-quantum cryptography, Quantum communication, Quantum key distribution, Edgar Allan Poe 1 Introduction For thousands of years, cryptography has been an ongoing battle between code- makers and codebreakers [1,2], who are more formally called cryptographers and cryptanalysts. Naturally, good and evil are subjective terms to designate code- makers and codebreakers. As a passionate advocate for the right to privacy, my allegiance is clearly on the side of codemakers. I admit that I laughed hyster- ically when I saw the Zona Vigilada warning that awaits visitors of the Pla¸ca de George Orwell near City Hall in Barcelona [3]. Nevertheless, I recognize that codebreakers at Bletchley Park during the Second World War were definitely on the side of good. -
War Machines: Women's Computing Work and the Underpinnings of the Data-Driven State, 1930-1946
Programmed Inequality How Britain Discarded Women Technologists and Lost Its Edge in Computing Marie Hicks HD 6135 H53 2017 The Library Mt. St. Vincent Univ. Halifax, N.S. B3M 2J6 The MIT Press Cambridge, Massachusetts London, England 1 War Machines: Women's Computing Work and the Underpinnings of the Data-Driven State, 1930-1946 In recent years, the restoration of Bletchley Park has attracted worldwide attention. The country estate in Milton Keynes, United Kingdom, was the site of the most important codebreaking operations of World War II and home to the first digital, electronic, programmable computer: the Colossus. The British-designed and manufactured Colossus computers, of which there were ten in all by war's end, were critical to the conduct of Allied wartime operations. Unlike their better-known U.S. counter part, the ENIAC, the Colossus computers were actually deployed during the war, actively changing its outcome. Kept secret for decades, the full import of the developments at Bletchley has only recently become widely known.1 Yet while popular culture has begun to recognize the importance of Bletchley's wartime operations, misunderstandings persist about the nature of the information work performed there. The 2014 blockbuster The Imitation Game, for instance, cleaves the Colossus computers from the narrative entirely in favor of building a "great man" narrative for a single codebreaker.2 Hidden within the story of Bletchley is a less popular narrative that cannot leverage the appeal of a lone genius and his accomplishments. Thousands of women worked at Bletchley during the war-most in tech nical roles.3 Although it is generally accepted that the striking and wide ranging roles of the mostly women workers within Bletchley Park give lie to stereotypes about computing as a traditionally masculine field, the contributions of these women have not been analyzed as constitutive of larger trends in the history of computing. -
Naval Section – Hut 4
The Mansion. Photo: © the2xislesteam The Enigma cipher was the backbone of German military and intelligence communications. First invented in 1918, it was designed to secure banking communications where it achieved little success. However the German military were quick to see its potential, they thought it to be unbreakable, and not without good reason. Enigma's complexity was bewildering. The odds against anyone who did not know the settings being able to break Enigma were a staggering 150 million, million, million, to one. Back in 1932 the Poles had broken Enigma, at a time when the encoding machine was undergoing trials with the German Army., the Poles even managed to reconstruct a machine. At that time, the cipher altered every few months but with the advent of war it changed at least once a day effectively locking the Poles out. July 1939, the Poles had passed on their knowledge to the British and the French. This enabled the code-breakers to make critical progress in working out the order in which the keys were attached to the electrical circuits, a task that had been impossible without an Enigma machine in front of them. Armed with this knowledge, the code-breakers were then able to exploit a chink in Enigma's armour. A fundamental design flaw meant that no letter could ever be encrypted as itself; an A in the original message, for example, could never appear as an A in the code. This gave the code breakers a toehold. Errors in messages sent by tired, stressed or lazy German operators also gave clues. -

ENIGMA TODAY Two young British seamen lost their lives when they boarded the German U-boat depicted in this image: U-559. What Lt. Tony Fasson, Able Seaman Colin Grazier and Canteen Assistant Tommy Brown recovered from the sinking vessel helped Alan Turing and his colleagues at Bletchley Park to turn the tide of WWII against Hitler. Even when Bletchley Park began to decipher encrypted Nazi messages, the U-boat version of Enigma proved much more difficult. Not until 1943, after British sailors drowned trying to recover current Enigma-code documents from a captured German vessel, were U-boat codes broken on a regular basis. It wasn't an easy chase on October 30, 1942. HMS HMS Petard and three other British destroyers were pursuing a Nazi sub in the Mediterranean Sea, not far from the Egyptian shore. U-559 was proving why U-boats were so dangerous. She was elusive. The chase lasted 16 hours before U-559's commander decided to scuttle his damaged submarine about 70 miles north of the Nile Delta. (Follow this link to a map where U-559 went down. Look in the lower right-hand corner.) Demonstrating courage that is hard to comprehend, three young sailors swam from Petard to U-559. -
Colossus and the Origins of Programmability
Colossus and the Origins of Programmability Draft for discussion at the 2016 SIGCIS Workshop. Do not quote or cite without permission of the authors. Thomas Haigh ([email protected]) and Mark Priestley ([email protected]) This is an initial draft of some material from our ongoing project to explore the history of Tommy Flowers, the ways in which Colossus was used and configured, and its place in the history of information technology. This work is sponsored by Mrs. L.D. Rope’s Second Charitable Trust. The current draft is very preliminary, so please do not quote, cite, or distribute without our permission. If names and references are confusing to you our apologies! Fortunately the basics of Colossus and Bletchley Park are well covered in Wikipedia. Colossus was a codebreaking device built by the British General Post Office at the end of 1943, under the direction of career telecommunications engineer Tommy Flowers. It entered use at Bletchley Park in 1944 to speed the work of codebreakers targeting what was then codenamed “fish,” a family of Lorenz teleprinter codes used for high level German military communication. Colossus was not a one‐off machine, like most early electronic computers, but the prototype for a family of ten “colossi,” in which later models incorporated some significant improvements. The machines were used by the Newmanry, a group under mathematician Max Newman, where ingenious codebreaking users discovered new applications for them which, in turn, shaped the provision of additional controls and capabilities in the later models. Unlike ENIAC, which began in modest secrecy but soon graced the front page of the New York Times, Colossus was highly classified and remained unknown to the public until the 1970s. -
