In the fifth section of the book “Blown to Bits”, the author talks about and explains data encryption, and how to defend data from people who are spying on it on the internet. The first part of the chapter mentions an example of legislation that was after the attack on the World Trade Center on September 11th. Senator Judd Gregg had the idea that all encryption agencies had to give access to their encryption data so that their information can be seen and tracked. The idea was accepted and turned out to be a success after the publishing of the Patriot Act.
To understand encryption, you must place yourself into the internet of the 90’s. At the time the internet was still new, all the data could be seen and accessed easily.The problem was that anyone could access your information and read it. This was a major issue because at that time, internet privacy was almost impossible.

Encryption on the other hand, is nothing new to humans.It has been used for millenniums, and can be traced as far back as ancient Egyptian history. There are many famous, but one stands out. Caesar Cipher, which is working on a very simple system, shifting the alphabet. This code is very simple to break, but there are other codes that are much harder. Equatorie of Planetis is a substitution cipher as well, but is not a shift of the alphabet. The way to solve this cipher is based on a letter system that’s called frequency analysis .It can be decoded with a method called frequency
Encryption converts data from a readable form to unintelligible text. Only authorized users are able to convert the data back into a readable format. (Sayles & Trawick,
In 1991 An ambitious senator named Joe Biden introduced legislation declaring that telecommunications companies “shall ensure” that their hardware includes backdoors for government eavesdropping (Declan). The proposal by Joe Biden was then followed by the clipper chip by the NSA and a bill approved by the House of representatives committee in 1997. It said that all encryption had to have backdoors for the government. Later that year it failed. The Silicon Valley firms told politicians that encryption was on web browsers. That then lead to the USA Patriot
After the attack, however, the politicians began to shift from protecting personal privacy to making government surveillance easier (Declan, 2011). For example, Mark Klein, a former AT&T engineer, provided proof in 2006 that the NSA has been creating a database of the citizens’ usage of data, with the cooperation of AT&T. Congress, which included then Senator Barack Obama, overrode the citizens’ petition to go over the accusations, and released AT&T from any liability with its involvement. President George W. Bush passed a law, legalizing warrantless wiretapping. As the government started to change its surveillance policies, it started to contradict previous policies. “As someone who was in the Financial District of Manhattan on 9/11, that was a horrifying morning for everyone… Yet I didn’t expect the terrorists would be so successful ultimately into getting us to abandon our core principles, and I think the founders would, in many ways, be ashamed of our response to the attack,” said Kevin Bankston, a lawyer for Electronic Frontier who is trying to restore the lawsuits
Encryption has been publicly available since the 1970s. Public-key encryption was introduced in the United Kingdom by a cryptographer named James Ellis and was officially published in 1976 by Whitfield Diffie and Martin Hellman. From these humble beginnings, encryption grew to what it is today with its advanced algorithms and sophisticated
The practice and study in securing communication between parties in presence of potential adversaries. A cryptographic algorithm or cipher is a mathematical function used in a plaintext in the encryption and decryption process. A cryptographic algorithm works in combination with a key (number, word, or phrase) to encrypt the plaintext. The same plaintext also
The uproar the Patriot Act received after Snowden drew attention to the topic in 2013 was tremendous. Following the 9/11 attacks, the Patriot Act was signed in late fall of 2001. It was created to ensure that there were precautionary measures to prevent terrorist attacks; the government wanted to enhance and increase the capabilities of law enforcement in order to thwart terrorism (Stefoff 15). However, many critics
After the terrorist attacks on September 11, 2001 the government took a big step forward in trying to protect the American people. Today, 12 years later, the government continues to protect the American people online in ways that are questioned daily. The questions remain, does the government really need to be watching us online? What privacy do we have while using our computers?
The advent of technology marks the beginning of the digital era. It is an era which created a whole new world called the World Wide Web (WWW) whereas the people therein are called “netizens”. With the proliferation of the internet usage across the world, netizens are able to meet other netizens from the other side of the world, to share their thoughts, pictures, and videos, and to interact through online workplace platforms, games, mails, and many more. It has created wide-range of opportunities for people to be informed, to be discovered, and to get jobs that further create jobs. Furthermore, it has introduced new jargons to our vocabulary that netizens up to these days still misunderstood since they keep on using them in statements in a different context for which it is intended save for the technical professionals with Computer Science or Information Technology background. Hence, with the fast paced development of the WWW and its boundless possibilities, netizens have learned the hard way on how to enjoy the features of the Web without compromising their privacy.
I feel that the Internet has changed personal privacy in many ways. The Internet can track and save everything you look up at any given time. Anybody who is computer savvy can look up anything you put up on the Internet. People on the Internet can take your photos without your permission; this can be dangerous if you are posting pictures of your kids and the rest of your family. Once you put in your information so many times the computer will start to remember all your information like your name, address, phone number, credit card number, and so on. Also if the company were to fail they would sell your personal information to other places so they can get paid for your information that is supposed to be kept secret between
Encryption is a cryptography in which one covers data or information by transforming it into an undecipherable code. Encryption generally uses a predefined parameter or key to perform the data change. Some encryption computations oblige the best approach to be the same length as the message to be encoded yet other encryption counts can take a shot at much more diminutive keys concerning the message. Separating is as often as possible described close by encryption as it’s backwards. Unscrambling of encoded data realizes the first data. Encryption is used as a piece of customary forefront life. Encryption is most used among trades over flimsy channels of correspondence for instance the web. Encryption is also used to secure data being traded between contraptions, for instance, modified teller machines (ATMs), cells, and various more. Encryption can be used to make automated imprints, which allow a message to be affirmed. Exactly when honest to goodness executed, an automated imprint gives the recipient of a message inspiration to acknowledge the message was sent by the affirmed sender. Modernized imprints are outstandingly significant when sending tricky email and distinctive sorts of cutting edge correspondence. This is by and large equivalent to standard composed by hand marks, in that, an all the more astounding imprint passes on a more multifaceted methodology for manufacture. Figure a figure is an estimation, strategy, or method for performing encryption and translating.
The internet has evolved from being a symbol of great revelation and innovation to a part of everyday life. It is used constantly to gather information and to make everyday tasks effortless for people worldwide. As such, having broad access to the internet causes internet users to rarely think about the consequences of putting their personal details on there for all to see. The conversation about internet regulations or internet privacy has been going on for years. It seems to be a never-ending debate about whether individuals should have complete internet privacy or no privacy at all.
Mr. Woods’ essay “Has the Internet Killed Privacy?” speaks about peoples’ opinions on privacy in the internet age and how much they are willing to share. The overall belief appears to be a mixture of some form of privacy because privacy settings can be setup and peer pressure. Those few that feel they have to use social media simply because everyone else is doing it think they have privacy by choosing to have only friends and families see their posts and do not bother reading the terms and agreements of their chosen format. I do not believe anyone is to blame. The companies are just trying to cover their bases; however I think that they can make things more user friendly and transparent. The terms and agreements are generally several pages
Encryption, also known as cryptography in the modern world, is the process of securing communication in the presence of third parties. Encryption is used to convert plain text data into unintelligible or useless ciphertext, and is used by many big institutions such as the government and businesses. My references discuss about why it is important that we learn about how to use encryption effectively, and how we can learn from previous methods of encryption. I will highlight what and how encryption has historically been used. My goal of this essay is to prove why we need to continue developing stronger methods of encryption.
“Encryption is a way to enhance the security of a message or file by scrambling the contents so that it can be read only by someone who has the right encryption key to unscramble it” (Microsoft). Encryption uses an algorithm to change plain text data to cipher text. It played a very important role in wars and in military circles to protect top secret information from foreign countries.
Encryption is just a fancy word for coding. When we talk about encrypting we really just mean turning information into really a hard to read secret code. Let’s say we have some secret agents in a movie and suppose there is an agent working in Washington DC they need to send a message to another agent in Russia. The best way for them to do this is by the two of you to meet up in advance, in person, and agree on a method of locking and unlocking all the messages they will send and receive in future.This method is called a secret key, because only the two of you will have access to it. When people want to find out what their saying to each other the attack is called a chosen ciphertext attack,CCA. In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. It is an attack model for cryptanalysis in which the cryptanalyst gathers information by choosing a ciphertext and obtaining its decryption under an unknown key. Cryptanalysis is the study of analyzing information systems in order to study the hidden aspects of the systems. People use encryption for a theoretical wall against anyone that wants to find out what is inside.
