What is encryption and why do we need it?
The concept of encrypting information has been popular for hundreds of years. Revolutionaries, scientists, political activists and lovers have utilized this technique to maintain privacy and confidentiality in their communications. As kids, we would take our secret messages and shift the letters of the alphabet by a specific number to create an encrypted message. For example, by shifting the letters of the alphabet by three we could change the word cyberlaw to fbehuodz. In encryption, a message is referred to as plaintext before changing it in any way. Data encryption is the process whereby plaintext data is converted to ciphertext data. Ciphertext data can only be read by a party with a secret decryption key. A method for encrypting text is referred to as a cryptosystem. There are many uses for encryption today, particularly, with the widespread use of the Internet. Encryption is used to verify messages, validate and authenticate users and authorize transactions.
Banks use encryption to secure customer identification numbers at ATM machines.
All U.S. electronic funds transfer messages are encrypted. Online vendors depend upon the security of credit card transactions in conducting business. Many political groups use cryptography to protect the identity of online users. Internet users want electronic privacy; freedom from observance by the government or other parties. Anonymity is vital to both privacy and freedom of speech.
Potential Abuses of Encryption:
The U.S. Government is concerned with the abuse of this technology at the hands of criminals, terrorists and hostile foreign governments. Encryption could impede their effo...

The availability of encryption codes will encourage a larger population of users to encrypt communications and will provide businesses worldwide a way to conduct transactions securely.
Arguments are made that the control of source code export discriminates against software distribution as opposed to encryption in print form. This greatly limits the expression of scientific ideas and thereby limits the marketplace for ideas.
The ability to remain anonymous is important to free speech and our right to privacy in communications on the Internet. If Clipper chips and escrow accounts become the standard, the U.S. government will be able to read private e-mail and determine the recipients. This would be a frightening departure from our proud tradition of preserving privacy in our communications and encouraging the free exchange of ideas and information.

- A tactic that underpins terrorist group's success is to blend in with the local populace. Terrorists wear no distinguishable uniforms. Use false identities. Hide from view inside protected sanctuaries such as mosques. As stated by a leading researcher and scholar on internet use by terrorists, “With over 1.4 billion persons on the internet… it is not surprising to find terrorists among that population” (Denning 2010, 1). Terrorist groups use the internet and other modern technologies for various reasons.... [tags: encrypted communications]

- Missing Chart Encryption Encryption is a method of programming data for security so that it appears to be random data. Only the people sending and receiving the information have the key to decrypt the message, which will put it back into its original form making it readable. The only people with the key are the people who are intended to read the message. Not many people know what encryption is. I took a survey of twenty students and asked two questions. The first question I asked was do you know what encryption means and the second question I asked was have you ever heard of anybody using encryption.... [tags: Data Security]

- Data Encryption The definition and importance of data encryption Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers must protect the customers’ personal information from hackers or competitors....

- Homomorphic Encryption allows access to highly scalable, inexpensive, on-demand computing resources that can execute the code and store the data that are provided to them. This aspect, known as data outsourced computation is very attractive, as it alleviates most of the burden on IT services from the consumer. Nevertheless, the adoption of data outsourced computation by business has a major obstacle, since the data owner does not want to allow the un trusted cloud provider to have access to the data being outsourced....

- ... (Anthes, 2014) This new software will greatly improve the strength of cryptography because it shows the weaknesses on current cryptography. The weaknesses will be reviewed and improvements will be made to strengthen the cryptography code making it harder for hackers to decrypt encrypted information. The algorithm developed by the French computer scientists and math – ematicians does not pose a threat to current cryptography being used by credit card and ecommerce companies. (Anthes, 2014) Even though the current cryptography being used is not threatened by the new algorithm it does show that groups are constantly working on algorithms to crack the cryptography protecting data therefore...

- History of encryption: Encryption is said to be as long as civilization. In fact, writing has been considered to be one of the first forms of encryption, as only the rich and educated civilians could read and understand the text. Moreover, looking at more recent times, the Navajo windtalkers was a language used by the American military in the second world war to communicate. This particular language was used as it so intricate that only American natives could make any sense out of it hence disadvantaging the enemy [B2]....

- Cryptography is the art of transforming something with a clear meaning into a hidden secret meaning. This process is done through encryption. Encryption has been around for a long time such as Skytale with Spartans, to Julias Ceasar. It has been a method for governments, religions and many other entities to protect their communications. In this era, encryption isn't just for large entities but it relates to billions of everyday Internet users. Stanford’s Center for Internet and Society states “Encryption helps human rights workers, activists, journalists, financial institutions, innovative businesses, and governments protect the confidentiality, integrity, and economic value of their activit...

- 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.... [tags: Encryption Writing Code Privacy Essays]

- Data Encryption I. What is Data Encryption. Data encryption describes the transformation of plain text into a different format that is meaningless read by human eye without being decrypted, so called cipher text, in order to prevent any unauthorized party to obtain information from the document. According to the Webster dictionary, “cryptography is the practice and study of data encryption and decryption - encoding data so that it can only be decoded by specific individuals.” Crypto is derived from the Greek word kruptos, to hide, from kruptein, which means hidden and secret....

- Encryption Data encryption refers to the transformation of data into a structure that makes it unreadable by anyone without a secret decryption key. It ensures that messages can be read only by the planned recipient. Encryption is the procedure of obscuring information to create it unreadable without special information. Only organizations and individuals with an abnormal need for secrecy have actually made good use of it. Nowadays, encryption is one of the most important technologies for maintaining your privacy and the security of important information.... [tags: Computer Technology]
