The Basic Concepts Of Cryptography Essay

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:

Data confidentiality is one of the three main IT security components which are data confidentiality, integrity, and availability (CIA). To keep your data confidential means to protect your data from unauthorized access. In other words, sensitive data are stored in a protected system that keep these information and data away from attackers and here the data confidentiality will measure the ability of the system to protect its data.

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.

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

Confidentiality: Confidentiality helps against the disclosure of data to an unauthorized users. It involves authentication that is identifying the user. Examples of threats to confidentiality are malware, intruders, insecure networks, social engineering, and poorly administered systems. In protecting confidentiality mechanisms like cryptography and access controls should be used.

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.

When a message is in its original form it is known as plaintext or cleartext and the process that involves masking the text to hide the content is known as encryption. Once a message is encrypted it is referred to as ciphertext . Cryptography or crypto for short has always served the same purpose of encrypting information for reasons of privacy, deception, or security. Cryptographic methodologies could date back to the ancient Egyptian era where standard hieroglyphs were altered to mask true meaning . It is more likely that the first introduction of crypto followed the invention of writing and evolved in line with forms of communication. The use of crypto has been seen as extremely advantageous in times of war, where communication

Confidentiality means that data is concealed and can only be seen by the intended recipient.

Cryptography simply means to encrypt your message into something else so that nobody can read it that is not authorised to read the information. Only that person can

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.
