Encryption in Today's Information Systems

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.

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).

M2 – Explain the operation and use of encryption technique in ensuring security of transmitted information

An encryption algorithm takes the original message and encodes it using the encryption key and creates an encrypted message. The only way to retrieve the original message is by decrypting the message using the encryption key. If the encryption key uses a 128-bit key is the same as saying that there are 128² possible key combinations. Algorithms are classified

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

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 a process that scrambles data to protect it from being read by anyone but the intended receiver. An encryption device encrypts data before placing it on a network. A decryption device decrypts the data before passing it to an application. A router, server, end system, or dedicated device can act as an encryption or decryption device. Data that is encrypted is called ciphered data (or simply encrypted data). Data that is not encrypted is called plain text or clear text.

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 encrypts to different cipher text with the use of different keys. The core of modern cryptography is the construction and analyzation of protocols of various aspects in information security such as data integrity and confidentiality, authentication, and non-repudiation.

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. This is a chart of the information I received:

Cryptography is the art of hiding or securing the important communication from the possible attacks of the outside.

Security and privacy are not new concepts. At 400 BC the Greeks used a transposition cipher. Individual letters were written on a long thin sheet of paper and then wrapped around a cylinder. The diameter of the cylinder was the key to find out the original letter. In this context, I find it necessary to give some definitions of related vocabulary in this field.

Abstract. This paper is on Cryptography. Cryptography is the art of writing and solving secret messages. People have been using the encoding and decoding of messages with pen and paper since ancient times. Cryptography has played an enormous role in human history as it was used in times of war. With the demand of today’s world of online security, digital Cryptography is in great demand to help people protect valuable information. This paper will focus on the brief history of Cryptography.

Primary purpose of cryptography is security. Cryptography has been present since thousands of years. Encryption for a longer duration is a priority in many organizations. One among them is military, which used cryptography to securely transmit a message. During 1980’s there is great necessity of securely communicating with others. Internet is present since 1960’s and the World Wide Web came into existence during 1980’s. Throughout the world people access the internet. A World Wide Web, an electronic portal, is extensively used by many people for communicating. People used World Wide Web to send electronic mails. This kind of communication increased around the world. As the information passed between the two people may be hacked by any other person, securing data and transmitting to the right person became important aspect. A deep emphasis of encryption and cryptography will help all

Encryption is a method of converting plain text to cipher text using some base keys and
