Watching and hearing stories of codes being used such as the Navajo code talkers, and the Germans inventing Enigma left me wanting to know about the subject. We can’t forget all the great movies that were made that helped showcased encryption and deciphering. The movie — Sneakers — where the phrase “It’s Not About Who’s Got the Most Bullets, It’s About Who’s Got the Information” had me wanting to know how to gain this knowledge and/or keep it from those who shouldn’t have it.
The word cryptography comes from the Greek word kryptos, meaning hidden or secret. Cryptography is defined as the art of writing or solving codes. Encryption and decryption are processes involved with cryptography. Encryption is a conversion of data into a form that one must decrypt. These messages are secured for many different purposes which include online transactions, health records, student records, military and defense purposes, and for the transfer of classified information. When the encryption process is used there is a sense of security and confidentiality which ensures those who are authorized to view or accept the information will be the only ones to do so. Only those who should have access to the classified information will be able to decode the message by using...

...nside that could move around based upon what shift was being used at the time.
In the Middle ages Polyalphabetic Substitution was used. Polyalphabetic Substitution uses more than one alphabet switching between them in a particular way. This has the advantage that you cannot use the same frequency analysis that you could with a monoalphabetic substitution. One of the more popular ciphers that use this process is called the Vigenere cipher. The Vigenere cipher was invented by by a Frenchman, Blaise de Vigenère in the 16th century. It would use two or more alphabets in the process usually by a word or phrase as the key. In the encryption process you would write the key repeatedly to fill the length of the message. Using the Vigenère square — a square that contains all of the Caesar Ciphers together — you will line up the key to the plain text to find the substitution.

- The Navajo Code Talkers During the Pacific portion of World War II, increasingly frequent instances of broken codes plagued the United States Marine Corps. Because the Japanese had become adept code breakers, at one point a code based on a mathematical algorithm could not be considered secure for more than 24 hours. Desperate for an answer to the apparent problem, the Marines decided to implement a non-mathematical code; they turned to Philip Johnston's concept of using a coded Navajo language for transmissions....

- After accepting Philip Johnston’s offer, Marine recruiters visited Navajo schools in Fort WIngate, Arizona and Shiprock, New Mexico to find the most educated Navajos to create an unbreakable and successful code. The Marines agreed to only take 30 Navajos, because they didn’t want to lose much money in case of a disaster. After a long search and the men were selected, the chosen Navajos were taken to a San Diego training camp in California (Aaseng 22). While living in the camps, Navajo men had to adapt to many different things such as new foods, living quarters, mechanical equipment, and competition which was never part of Navajo culture....

- Gunshots whistle overhead. Their screams combining with the patterned explosion of guns, and land mines, enfolding all in a column of death and smoke. The symphony of sounds, seamlessly morphing into a ghastly melody: one of lament and agony. Harsh sounds saturating the shredded landscape with a nightmarish quality. Your tortured senses protest, their cries of indignation lost amidst the clamour of soldiers. Fixed and rigid in place, soldiers’ minds and bodies slowly succumbing to the inevitability of death....

- Navajo Code Talkers: Unknown Heroes Seldom has it ever occurred that heroes to our country, let alone in general, have had to wait decades for proper acknowledgement for their heroic deeds. This is not the case for the Navajo Code Talkers. These brave souls had to wait a total of six decades to be acknowledged for their contributions to the United States and the Allied Forces of WWII. The code talkers were an influential piece to the success of the United States forces in the Pacific. Thus had it not been for the Native Americans that volunteered to be code talkers, there might not have been such a drastic turn around in the fighting of the Pacific Theatre.... [tags: World War II]

- Introduction Pearl Harbor went under attack by the Japanese in the Pacific. During this time the news went over the radio airwaves and everyone who heard the news knew that war was imminent. The Navajo people had a reason to resent the white people during that time, but to protect their land and their way of life on the reservation was of upmost importance to them. Regardless of their opinions, many would enlist into the Marine Corps. There came about the first Twenty nine Navajo men that use their native language to defend their way of life....

- The Navajo and Their Impact on World War II and the Lives of All Native Americans Throughout the history of the United States, the Native American people have been the victim of the European immigrants that came as early as the 1400’s. These immigrants, for the majority of their American occupation, cheated, uprooted, and killed the Native peoples of America, and the Natives endured it for hundreds of years. Today, they are an accepted part of American society as people are more tolerant, but it was not until very recently that they began to move towards assimilation....

- CHAY-DA-GAHI is Navajo for tortoise and U.S. codeword for tank. DA-HE-TIH-HI meaning humming bird was codeword for fighter plane. NE-HE-MAH meaning our mother was codeword for America. These are the code words uttered by the Navajo people during World War 2. The code was unbreakable and was derived from an ancient language that forever changed modern warfare. Ultimately, the code and the small band of warriors that uttered it left the axis powers scratching their heads in frustration. When we think of America, we often attribute the American people as those that came over on a boat.... [tags: navajo people, dine, world war]

- Residing in the Southwest United States, the Navajo Indian tribe is one of the largest tribes in America today. In their own language, they refer to themselves as Diné which means “the people”. They are an old tribe with descendants tracing their roots back to the thirteenth century. The first contact that the Navajos had with white settlers was during the Mexican American War in 1846. The United States conducted peaceful relations with the Navajo for over fifteen years. Forts were built to help protect the Navajo from Spanish/Mexican raids on the Navajo’s cattle....
