Cryptography Is A Science That Transforms Information Into Secure Form By Providing Basic Protections

Encryption technique is the translation of data into a secret code that will prevent hackers or identity thieves from being able to break or read the data that is sent across the network.

When a fellow general received the message, he would wrap the paper around his corresponding scytale to decipher the message (Tyson 2014). Since the advent of computers though, encryption has become increasing important and relies almost solely on cryptographic means to secure information. When speaking about encryption today, it refers more to the process rather than the mathematical formulas used to scramble data. The basic idea behind encrypting a computer message is such that it is scrambled with a sequence of random bits, known as a key, and only parties with the corresponding key can transpose it back into a comprehensible format. These keys are created via a cipher, otherwise known as an algorithm. When a user sends a message, known as the plaintext, across a network, the computer applies an algorithm to the information to encode it, resulting in a ciphertext (Encryption Basics 2014). This method can be best summarized visually:

Encryption is the conversion of electronic data into another form, called cipher text, which cannot be easily understood by anyone except authorized parties. The primary purpose of encryption is to protect the confidentiality of digital data stored on computer systems or transmitted via the Internet or other computer networks. Modern encryption algorithms play

Encryption is a process that turns information that is plainly readable into scrambled form in order to preserve the authenticity, integrity, and privacy of the information that passes through the security perimeter (Michael E. Whitman, 2009). It is the conversion of electronic data into another form, called ciphertext, which cannot be easily understood by anyone except authorized parties (Rouse, 2014).

Encryption is a method of encoding a message or information before sending it, so unauthorized users can’t access it without permission and only the person who has authorised access to it can decode it. Encryption is used to keep things secure and keep things confidential within the organisation. For example let’s say you have a chat with a friend on Skype, when you’re sending a message to him, that message will display as random symbols until he receives it, which then decodes it and makes it so that only he can read it. This allows the communication to be secure and private, no one will be able to know what the message says.

            In the past decade, rapid advances have been made in the field of cryptography.  These advances have brought considerable

Encryption is a process of converting Plain text into Cipher text. This un-readable message can be communicated over an unsecure network without the fear of loss of integrity and confidentiality. Encryption process is done using encryption algorithm.

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

An encryption key is a code used by an algorithm to scramble and unscramble data.

With the evolution of Internet, new technologies are appearing and new ways of doing business are slowly changing the world. One of those new business process are online stores. This technology allows user to sell or buy their products or services online. These data exchanged during those operations are extremely very critical and no error with the manipulation of these important information can be allowed. For the protection of those personal and financial information, security plays a big role in this industry.

This paper discusses the history of data encryption technology. It also touches on several aspects of data encryption technology. Furthermore, an attempt will be made to answer several key questions like what is data encryption technology (DET). It will also detail some of the history of DET, how DET affects the lives of people in America, and some of the future implications of this technology.

After reading this chapter and completing the exercises, you should understand the following about cryptography.

Pseudo irregular number generations, symmetric cryptography (stream and piece figures), methods of operation, hash capacities, message and substance confirmation conventions, zero information, traps conveying open key encryption and computerized marks, key appropriation, mystery sharing.

The conversion of data into ciphertext, that cannot be easily understood by unauthorized people. It is the only way to protect information in transit over the Internet.

Abstract— For preserving the security of data there has been tremendous research areas evolved and explored since few years. Cryptography is seen to be the dominant strategy in the information security domain. To differentiate security of multimedia data, visual cryptography is seen as the prominent way for data confidentiality and secrecy of information being distributed.
