Advantages And Disadvantages Of Cryptography

Public key and private is a type of encryption technique that can be used ensuring that the communication on the network is secured. When you sending a message to someone through the network, will need to use the public key of the receiver and the receiver will use the private key to decrypt the message. This encryption will avoid unauthorised access to the message such as reading

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into

According to the Newton's Telecom Dictionary, cryptography is, "the process of concealing the contents of a message from all except those who know the key," (207). It is also defined as ". . . the science, or art, of secret writing," (Huffman 2). The word "cryptography" originated

Encryption is one of the most important technologies of cybersecurity designed to protect the confidentiality of data. Encryption uses a complex mathematical formula and a key which randomizes and creates a coded or encrypted message. Only the party that the message or data is originally intended for can read in plain text by using the appropriate key to decrypt the data. Some encryption algorithms such as AES (Advanced Encryption Standard) are very complex

Cryptology is derived from the Greek words, kryptos and logos. The literal meaning of cryptology is “hidden study” or “the study of the hidden.” The science of cryptology is split into two separate sciences, cryptography and cryptanalysis. Cryptography is kryptos and graphein, meaning “hidden writing.” Cryptanalysis is from kryptos and analyein. It means “to loosen or untie the hidden.” Cryptography and cryptanalysis

Abstract: The use of encryption by individuals is growing at a tremendous rate, and since 1991 cryptography issues have engulfed both the U.S. government as well as the computing industry. One of the most controversial of these issues is whether encryption should be made supremely secure to the highest-level current technology will allow, or whether a "master key" should be locked away somewhere, only to be used when absolutely justified.  Both sides of the issue have their benefits and detriments; the problem is finding the middle ground that will provide the greatest benefit to society.

As implied by the fourth, ninth, and fourteenth amendments to the Constitution of the United States, all citizens of the United States have a right to privacy. In the digital age, where all of our most important and personal information is stored digitally, we must have a way to protect this digital content. To protect our data we use encryption where contents of files are scrambled and distorted and can only be made legible by someone who knows the decryption key. Governments in Europe, Asia, and America are currently engaged in undermining the encryption and privacy rights of their citizens either by demanding backdoors or

As Paris tremble for fear from terrorist attacks that have killed 129 people, fierce blame for the massacre is falling on American whistleblower Edward Snowden and the spread of strong encryption catalyzed by his actions. The lastest deadly terror attack is leading the crypto-war as a contemporarily crucial issue. The crypto-war refers to a decades-long political battle over the legality and popularity of encryption around world. Since Snowden exposed the vast surveillance and spying done by Western governments, people have become to demand more strong encryption to shield their Internet activities from prying eyes, so encryption has been become popular rapidly. Now everyone uses encryption from e-commerce websites to terrorists. The key

Public/private key encryption is the best known example of an asymmetric key system. With public/private key systems, each secure station on a network has a public key that is openly published or easily determined. All devices

Moreover, it is important to note that while cryptography is necessary for secure communications, this report is not by itself sufficient. The reader is advice then, that the topics covered in this paper only describe the first of the many steps necessary for better security in a number of situations.

Protecting data through cryptography from unauthorized eyes is a high priority for organizations that store personal information. Cryptography is the process of hiding the real meaning of a message through a pre-determined code that is only known to the person encrypting and decrypting a message. Different forms of cryptography can be seen in our everyday life from the word puzzle in daily newspapers to secretaries writing in short hand. Cryptography has been around since the time of the Egyptians and has made many advances through the years.

Over the years, cryptography has been used to protect secrets, in a military capacity to make sure that either hackers, enemies of the countries, do not intercept sensitive formation. Ciphers, and encryption blocks are becoming so hard to break even the best super computers cannot break the codes in a timely fashion. Encryption has been improved over the years, also has been around for thousands of years and this paper is intended to explain about different forms of cryptography that either has been used or is still in use to this day. This paper is about

Nowadays there are a lot ways of payment for goods and services. For instance, debit and credit cards, Android Pay, Apple Pay, e-Check, and Visa Checkout. But there are also ways for us to earn it, use it or counterfeit it where it is called cryptocurrency. Most of countries in this world used this type of currency. What is cryptocurrency? A cryptocurrency or in the other word crypto currency is a digital asset that was designed to work as a medium of exchange using cryptography. The function is to control or maintain the creation of additional units of the currency and also to secure the transaction. In other way, Cryptocurrency is a modified electricity into a line of code with the value of money. In the simplest of terms, cryptocurrency is a digital currency. The first cryptocurrency is Bitcoin which was created in 2009.

Technology plays a major role in our lives. Technological advancements have made significant contributions to how our world operates today and how we go about our daily lives. One question many have is this: will our money become completely digital like so many other things have? Digital money should not become the United States' only way of payment in the future because technology is not always reliable, hackers can easily use it for personal gain, and it is only controlled by its users.

When Information and Communication Technology is evolving rapidly, it is a challenge to keep up, and integrating it in the classroom is the other concern. Technology in education has become the buzz word in every educational environment (Chhabra, 2012). Learning now occurs almost everywhere. The teaching and learning process is not the traditional bricks and mortar anymore which confined between four walls. ICT tools like the internet, e-mails, printers, scanners, computers, interactive boards, i-pads, audio equipment, digital single lens reflex camera, smartphones, tablets, ‘phablets’, social networking medias are ruling the world of education. From the world’s most famous search engines like Google to the world’s most visited
