Research Project Encryption

Should the US government limit the strength of encryption products to eavesdrop on people’s everyday life?

I remember exchanging secret letters with my friends in Japan as a child. We developed a code in which each letter of the Japanese alphabet was replaced by the one that follows it. For example, if we had used English, "Z" would have been replaced by "A". Each of us had the key to understanding this code but outsiders didn’t, so we didn’t have to worry if one of our brothers intercepted our letters. We loved our secret communications.

These letters actually used a simple kind of encryption, not so different from the one Julius Caesar used for the secret messages he sent his Roman generals throughout Europe. He, also, didn’t worry if his enemies stole the messages because without the key, they couldn’t read them.

Today, as well, encryption is used to hide sensitive information. It is used not only by spies but also for common telecommunications, such as faxes and e-mails. Encryption is also important for many everyday uses like Personal Identification Numbers (PINs) for bank account, credit card security and access to controlled areas in buildings. Encryption ensures privacy by keeping things behind a locked door of sorts.

But what happens if there is something dangerous, very dangerous behind

that locked door? What if the information that is being kept private and secure is a potential threat to the safety of others? What if my friends and I had been plotting to blow up our school or to plan a way to hurt our brothers? Shouldn’t our parents have had a way to know what we were conspiring? In other words, how private should private be?

This is the question central to a brewing controversy between privacy advocates and the U.S. Federal government. Legal, professional, and ethical issues are being debated as are the limits that can or should be placed on developing encryption technologies. At stake are personal freedoms, the privacy of financial and medical records, as well as the fate of entire, nascent industries in the high-tech world.

The system of encryption

To start off the examination of this complex topic, let’s start with the definition of encryption: a process of disguising a message so that only its legitimate recipient can understand it. There are two steps to the encryption process, the first of which is also called encryption, and the second which is decryption.

  • FERPA- Family Edicational Rights and Privacy Act

    1103 Words  | 3 Pages

    Privacy was once taken for granted in public education, but now through the 1974 law, Family Educational Rights and Privacy Act it is pushed to the forefront of the minds of every educator in the United States (Cossler, 2010). This law has paved the way for many lawsuits regarding privacy of student’s records, which have left teachers scared, undereducated and unaware of certain regulations of the law. FERPA laws provide protections for students, but also allow access of all student records to the student’s custodial parents, which in some situations has cause problems and in some cases have specifically brought clarifications of the law. Has the Family Educational Rights and Privacy Act provided the much needed privacy for students or created an overboard policies?

It is descriptive and provides a lot of information but in the same time it is also analytical because it presents different aspects and primary sources of the Serb’s history. The parts of the book which relate to the origins of the First World War and the Balkan crisis are focused on the conflict between Serbia and Austria-Hungary, so it does not analyze all origins of the War, but it does analyze in depth the influence of Balkan nationalism for the outbreak and provides a large number of evidences for his arguments. The book compares and contrasts political and cultural history of Serbs and it is credible and objective. Relating to the First World War he also provides many primary sources and perspectives of different scholars.

  • We Must Have a Right to Privacy

    3741 Words  | 8 Pages

    The Information Age has emerged with speed, excitement, and great promise. The electronic eyes and ears of technology follow us everywhere. There are those enamored with the rush of technology, who b elieve that the best of worlds is one in which everyone can peer into everyone else's lives. In fact, we now live in a world consumed with "the ecstacy of communication" (Karaim 76). Americans line up to reveal their darkest secrets of their m ost intimate moments, or just "hang out their dirty laundry" on the numerous television talk shows. The more exposure, the better. So it may be absurd that we should worry that our privacy is being endangered, our personal life and even our se crets made public. The loss of privacy is on the fast track, and the high-tech Information Age is a willing conspirator. Somebody, somewhere, may know something about you that you'd prefer to keep private: how much you earn a year, what you paid for yo ur car or house, whether you've had certain diseases, what your job history is. Your medical, financial, consumer, and employment records are in computers and may be flying through cyberspace without your knowledge or consent.

  • Personal Privacy and the Government

    1395 Words  | 3 Pages

    The United States government is up to its ears in the personal information it has collected from its citizens. Americans are becoming increasingly “aware of these slowly eroding walls of privacy,”(Hirsh) and more than half polled admit concern “about the overall accumulation of personal information about them “by […] law enforcement, government, […] and other groups,” though “they accept it as an unavoidable modern phenomenon” (Hirsh). The question is, how far is too far to trust the government with the collection, proper storage, and usage of this information? Studies show that “Americans believe that business, government, social-media sites, and other groups are accessing their most personal information without their consent” (Hirsh). People should be given the ability to admit or deny access to their personal information. The government does not have a right to use whatever information it wants for any purpose it wishes. Michael Hayden, once the NSA director for seven years, says, “Even I recognize that it's one thing for Google to know too much, because they aren't putting me in jail. It's another thing for government, because they can coerce me” (Hirsh). The United States government's ability to collect information about its citizens and residents should be restricted by what kind of information it can take, how it can acquire it, and what it can use it for.

    Women’s rights in Mesopotamia were not equal to those of men. However, during early periods women were free to go out to the marketplace, own and sell property, attend to legal matters for their absent men, and engage in business for themselves. Women of higher status, such as priestesses and members of royal families, might learn to read and write and be given considerable administrative authority. Various powerful goddesses were worshipped and in some cities were the primary deities. However, women’s position varied between cities and changed over time.

  • Data Encryption

    780 Words  | 2 Pages

    Encryption converts a message in such as way that its contents are hidden from unauthorized readers. It is intended to keep messages and information as a secret. Plaintext, also known as clear text, is the plain or original message, which is has not yet been encrypted. Once the message is encrypted it is then called a cipher text. This process is obviously referred as encryption. The exact opposite process is called decryption. Encryption is the most successful way to attain data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Data encryption is a means of scrambling the data so that is can only be read by the person holding the key, a password of some sort. Without the key, the cipher cannot be broken and the data remains secure. Using the key, the cipher is decrypted and the data is returned to its original value or state. Each time one desires to encrypt data, a key from the 72,000,000,000,000,000 possible key variations, is randomly produced, and used to encrypt the data. The same key must be made known to the receiver if they ar...

Cryptography is the study or science of techniques of secret writing and message hiding. Cryptography constitutes any method in which someone attempts to hide a message, or the meaning, in some medium. One specific element of cryptography is encryption, which hides the data or information by transforming it into undecipherable code. Encryption uses a specified key to perform the data transformation.
