World War II Encryption - The Enigma Machine
The Enigma machine is an advanced electro-mechanical cipher machine invented by a German, Arthur Scherbius, at the end of World War I. Its only function was to encrypt and decrypt messages. It was used by all of the branches of the German military as the main device to secure wireless communications until the end of World War II. The use of the Enigma machine was an important part of World War II history. The Enigma machine has a look akin to a typewriter. Similar to other rotor machines, the Enigma machine is a combination of mechanical and electrical subsystems. An electrical circuit is created by having the mechanical parts arranged in a certain way. A circuit is completed

At the same moment, the right wheel N is being moved forward by one step. This action ensures that a new alphabet is being used for every keystroke. A current goes to the letter A in the plugboard. There is no plug placed in this letter, so the current continues until the letter A in the entry wheel. This wheel's only use is to connect to the other wheels. The complicated internal wirings in the wheels N, M and L result in the current passing through them being a combination of the letters. The same can be said about the reflector R. The current is returned backwards through the three wheels L, M and N causing a change in the letters in every step. The current proceeds back to the plugboard to the letter F. A plug connecting the letter F and the letter D redirects the current to the letter D. Finally, the letter D lights up on the lamp board. Thus, the encryption is complete: A is now …show more content…
A clerk in the German government codes department, named Hans Schmidt, who got his job by way of having a senior military commander for a brother. His complicated personal life led him to contact the French intelligence in 1931 and offer to sell them top secret documents for money. Schmidt gave them both the Enigma machine's operating manual and its settings lists. Even with the information, the French and British code breakers at the time could not crack the code, so they contacted the Polish code breakers. The Polish realize that the only way to decipher the Enigma codes was to build an Enigma-like machine, which they do in 1932. The Polish did have success with the German information, breaking codes for six years, but they never told the French. After six years, the Germans continued to improve their Enigma machines and made it harder for the Polish to crack their codes. Another year passed before the Polish deigned to tell the French and British, one month before Hitler invaded Poland. While the invasion could not be prevented, the knowledge the Polish provided of how to break the Enigma codes helped the
One of Great Britain’s most important naval developments was the founding of the top-secret Office of Naval Intelligence, better known as Room 40. Specializing in cryptography, “the science of writing in secret code” in order to hide sensitive information, Room 40’s cryptanalysts worked around the clock to break the secret code. Decryption is vital in secret transmissions concerning strategic war movements, as the enemy will be looking to intercept information concerning movements and positioning. Great Britain was aided in that the German Navy started the war with three primary codes, and within four months the British Admiralty possessed physical copies of all three of them.
False information that was released by the British was actually successful because it had people from Germany not being able to trust that the right thing was going to occur. The false information then continued
Espionage was vital in the war effort of both the allied and axis powers during World War II. Espionage can take many different forms. Deception, leaking of false information, coding and encryption of information, sabotage, and sending spies in to gather intelligence are all were all used during the war and were all effective. Many of the turning points for the allied forces occurred due to various forms of espionage and deception. Depending on which side of the fence you're sitting on, espionage was either a blessing or a curse.
The RSA encryption is related to the cipher of Julius Caesar (1300s) that shifts three letters to encode messages. The cipher of Julius Caesar was used in war to send messages securely. Here is how Caesar encodes his message using the cipher. First Caesar assigned A through Z to 0 through 25. For instance A is zero. Second, add three to each numbers.
The result of World War II was affected by many different factors. One major factor which affected the war was the weapons and artillery used during the war. Since the beginnings of time, weapons have always been around. From swords and knives to nuclear weapons and missiles, weapons have evolved greatly throughout the years. The weapons and artillery used in World War II basically were evolved types of weaponry that were used during World War I (Military History 1).
From 1914 to 1918, the major powers in Europe were at the war. The war was Germany and Austria- Hungary against France, English, Russia, and later the United States joined. After 4 years of intense war, it finally ended with the Germans surrender. After the war has ended, the countries agreed to sign a peace treaty in 1919. However the treaty contained some major flaws that would eventually result World War 2.
There were a couple things that lead to the shift of the American position regarding the our entrance into World War 1. Some things that made America want to join the war were the Zimmerman Telegraph and the sinking of the RMS Lusitania. Over time you can see how the Americas views or President Wilson's views changed about us entering the War. Using politics and conflicts as a theme we will see who has the power and what the roles of the people were.
President Wilson addressed congress in 1917 to seek declaration of war against Germany in order to make "the world safe for democracy". Although, Wilson's words indicate that democracy was a crucial factor for American entry into War World I, the notion of American ideals of democracy were challenged by American women's demand to vote.
“War is unorganized murder, and nothing else” (Harry Patch). In World War 1, which was first called the Great War, there were many causes of the war breaking out. The Great War started August 1st 1914 days later after the assassination of the Archduke Franz Ferdinand and his wife, Sophia, when they visited Bosnia. Many soldiers went to war for no reason but to fight for their country. The Great War was not only affected by the soldiers, but also by the civilians as well. Women replaced men in factories, offices, and shops while the men were at war so that everything would be working smoothly. The main underlying causes of World War 1 were the alliances and imperialism in Europe.
During the early stages of the war, most of Germany’s victories were because of the success of blitzkrieg, or lightening war. Blitzkrieg tactics emphasised mobility and the concentrated use of armour and air power to overwhelm an enemy. Blitzkrieg was especially successful in flat, open countryside and was supremely suited for the Polish campaign in 1939. It was with blitzkrieg, as well as Germany’s superior tactics, effective use of armour, airpower and modern equipment, plus with the support of the USSR that the Germans used to overwhelm Poland in only 5 weeks. Two days after the German troops entered Poland, Britain and France declared war on Germany. Hitler did not want this because it was a distraction from his main aim, to attack the USSR.
In the war between countries, technology has played a huge part in the outcome; this is especially evident during the time of World War II. Technology in warfare consisted of weapons, vehicles, aircrafts, and chemical reactants. Technology during World War I was lacking and countries knew when World War II began that in order for them to be victorious they must have the most technologically advanced weapons and other devices or systems that would benefit the nation. The Allies were victorious in WW2 because they made better use of the available technologies than the Germans, advancing in communication/detection systems such as sonar and the radio, as well as, weapons including the atomic bomb, and bomber aircrafts.

Although the majority of people cannot imagine life without computers, they owe their gratitude toward an algorithm machine developed seventy to eighty years ago. Although the enormous size and primitive form of the object might appear completely unrelated to modern technology, its importance cannot be over-stated. Not only did the Turing Machine help the Allies win World War II, but it also laid the foundation for all computers that are in use today. The machine also helped its creator, Alan Turing, to design more advanced devices that still cause discussion and controversy today. The Turing Machine serves as a testament to the ingenuity of its creator, the potential of technology, and the glory of innovation.
Bombs being fired, grenade pins being pulled, guns being shot, and land mines exploding are the sights and sounds of World War II. World War II was a historical moment for the whole world that should never be forgotten. World War II dealt with issues that had to be smoothed over after World War I. After a twenty- year hiatus, World War II began between the Axis powers, and the Allied powers. World War II should be remembered because of the bravery of the soldiers, the uniting of countries, and the patriotism of soldiers.
Cryptography was first used long before the invention of computers. One well-known system was attributed to the reign of Julius Caesar (Klein ix). Another example is the famous Zimmerman telegraph, which was sent from Germany to Mexico during World War I (ix). In a more modern setting, cryptology was mainly used by the government until the late 1970s (Simpson 1). This is largely due to the fact that computers were too expensive, so not many households or businesses had them (1). However, after the computer revolution, cryptology became more public, especially in the business industry where there was a greater need to secure things like transactions (1).
