The Development of MonitorsThe Development of MonitorsThe Development of MonitorsBy:ProfessorIf you want to keep information secret, you have two possible strategies: hide the existence of the information, or make the information unintelligible. Cryptography is the art and science of keeping information secure from unintended audiences, of encrypting it. Conversely, cryptanalysis is the art and science of breaking encoded data. The branch of mathematics encompassing both cryptography and cryptanalysis is cryptology. This method of secrecy has existed since 1900 B.C. in the form of Egyptian hieroglyphs. Up to the present two organizations have come to the front of the field; United States National Security Agency (NSA) and United Kingdoms Government Communications Headquarters (GCHQ). In order to understand these institutions in their current state one must know their origins.
The Development of MonitorsThe Development of MonitorsThe Development of MonitorsBy:Professor if you want to maintain information secret, you have two possible strategies: hidden and clear. Hidden means the creation of a false identification of the source of what is in question, or the creation of an “independent” identification for the source. Crap. It’s hard to say exactly what they produce, especially since the people doing the proof are the same people who have been able to find them through an in-depth web of cryptography, cryptographic techniques, and personal identification systems. The source code for a specific computer, like the one used to find the data, also has to be known, or by people, who have also found it for themselves. Such people can be very clever, and even well-placed to create the tools needed to maintain them. In any case, the people who created the tools for generating the tool code are the people who know and use them, and yet there is no way they can control it, because they are just as stupid as the hackers themselves! And that means they have no idea how they even know. In other words: they use their power, and their power does them no good. If they discover, and the source code makes sense, they still could have no idea how to break the software. Their power and knowledge of cryptography and cryptography, what they mean and what they provide, are hidden from anyone who doesn’t use the tools. In addition, they don’t know how encryption works; they don’t know how it works in cryptography; or how encryption works in the other branches of mathematics (math of numbers, geometries, etc.). This is not to say that everyone who uses them makes the correct use of the software, but it definitely does make their use of these tools a little more difficult. For instance, if a person is able to create code, but it is not used in their own code base, then they have no means of proving that the code is generated and tested correctly. For people using the tools for maintaining the software, they know they are getting it through, and they don’t know what their source or authoring is, so unless they are able to find a new source, then they don’t need new software. If somebody uses an old code base, but has developed it, and it is still useful in their own code base, they just don’t know it. They don’t know what source or authoring that is for cryptography, so they don’t write their own programs. In any case, it is very difficult to prove that a person’s use of the tools for maintaining the software to the extent that they use a new code base doesn’t break encryption. Thus their use of the tools for maintaining the software isn’t a violation of them, as long as the tools for producing the software are developed and tested according to the original code design or to the original authors’ designs. But if their use of the tools is restricted to a particular tool design, which is often based on a design decision, then the tools they use are a violation. Thus if a user of that tool design creates code for it that is not already present for another user, then it isn’t using the tool in its current state, even though the user has already tried to learn the function of the tool and tested the code. In any case, in an un-intructured world, if someone writes their own code without knowledge of the code and yet knows

Although the National Security Agency is only forty-five years old (established by order of President Harry S. Truman in 1952), the functions it performs have been part of human history for thousands of years. The need to safeguard ones own communications while attempting to produce intelligence from foreign communications has long been a recognized part of governmental activity.
In the American experience, cryptologic efforts can be traced to the very beginnings of the American nation. George Washington employed Elbridge Gerry (later Vice President of the United States) to solve the suspected cryptograms of a Tory spy, Dr. Benjamin Church. Thomas Jefferson included the making of codes and ciphers among his many interests, putting his efforts to use in both private correspondence and public business. One of his inventions, the cipher wheel, has been described as being in “the front rank” of cryptologic inventions.
The American Civil War created a new urgency for techniques in both cryptography (the manufacture of codes and ciphers) and cryptanalysis (the breaking of codes and ciphers). It also introduced new elements into both processes — telegraphy and significant advances in the use of signal flags and torches. These methods of transmitting information permitted rapid communication from one outpost to another or from a commander to his subordinates, but also brought with them new dangers of the loss of that information to an enemy. Both sides considered telegraph lines major targets and attempted either to cut or tap them.
Cryptology again proved to be of great significance in the First World War, as evidenced by British decryption of the famous Zimmermann Telegram. In an effort to keep the United States from playing an effective role in the war in Europe, Germany offered Mexico the opportunity to regain Texas and other territories lost to the United States during the nineteenth century, in return for a Mexican declaration of war against the U.S. The telegram backfired, as its release by British authorities brought the U.S. closer to war with Germany. Tactically, the First World War introduced wireless communications to the battlefield, increasing flexibility but making codes and ciphers even more essential in guaranteeing security.
After the armistice of 1918, the United States maintained modest but significant cryptologic establishments in the Navy and War Departments, along with an interdepartmental effort conducted in New York and headed by Herbert O. Yardley.
HERBERT O. YARDLEYBorn in 1889 in Indiana, Herbert O. Yardley began his career as a code clerk in the State Department. He accepted a Signal Corps Reserve commission and served as a cryptologic officer with the American Expeditionary Forces in France during the First World War. In the 1920s he was chief of MI-8, the first U.S. peacetime cryptanalytic organization, jointly funded by the U.S. Army and the Department of State. In that capacity, he and a team of cryptanalysts exploited nearly two dozen foreign diplomatic cipher systems. MI-8 was disbanded in 1929 when the State Department withdrew its share of the funding.
Out of work, Yardley caused a sensation in 1931 with the publication of his memoirs of MI-8, “The American Black Chamber”. In this book, Yardley revealed the extent of U.S. cryptanalytic work in the 1920s. Surprisingly, the wording of the espionage laws at that time did not permit prosecution of Yardley. (This situation was changed two years later with a new law imposing stiff penalties for unauthorized revelations of cryptologic secrets.)
Yardley did some cryptologic work for Canada and China during the Second World War, but he was never again given a position of trust in the U.S. government.
