Cryptography Is Art Of Secret Writing

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

Moreover, encryption requires use of a key or cipher, which is used to lock and unlock the hidden data. Such a key is necessary to allow the hidden data to be viewed in an intelligible manner by those who are authorized to view it. However, there is always a risk that the encryption key might fall into the wrong hands, thereby allowing the information to be accessed by unauthorized viewers.

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.

Encyption takes data and transforms it into unreadable jargon until a key is used to unlock or decrypt the data back to its original form. Due to its near infallibility, encryption is one the most best ways to secure data (Williams & Sawyer, 2015).

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

Availability which aim to guarantee the accessibility of information to authorized users and/or applications only.

According to unabridged dictionary the term integrity is derived from the Latin words integrates and integer, which means an entire, untouched state of a thing. Integrity basically involves keeping the measurements of reliability, correctness and trustworthiness of documents along its whole existence circle. These moderations basically include record authorization and user access controls. Variant control checks maybe used to preclude inaccurate replacement or accidental deletion via legal shoppers becoming an obstacle. Similarly a few method have to be in vicinity to find any changes in information that might come up due to non-human-brought about events similar to an electromagnetic pulse or server crash.

Initially we should start with identifying and defining the four security components to ensure we have a clear understanding of what they are and how to implement them. The components of information security are Confidentiality, Integrity, and availability also known as the CIA triad. Confidentiality in Information Security is defined as the protection of information from disclosure to unauthorized parties (Chia, 2012). Integrity in Information Security is defined as protecting data from being modified by those not authorized to do so. Authentication is defined as proof that the individual requesting access is who they say they are. Non-repudiation is an assurance that someone cannot deny something, in information security this might be completed

Cryptography, at least in some form, has been around since 1900 BC where the first known evidence had been seen in an Egyptian tomb of a nobleman, Khnuhotep II. Here, there are unusual hieroglyphic symbols that the scribe used in the place of more ordinary ones that one would expect. It is thought that the purpose of changing these symbols, it was not to hide the message, but make it seem like it was more dignified. However, evidence of cryptography has been traced back to the most of the major early civilizations. Arthasharta, an ancient Indian treatise, helps tell of an espionage service and mentions secret writing that their spies had used on assignements. Julias Caesar also had his very own cipher. It was a form of encryption to relay secret messages to his generals that were on the war front. It is a substitution cipher, and the most widely mentioned in history. A substitution cipher is where a plain text message would have each character

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

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:

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