Encryption And The Security Of A Message

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.

Generally speaking, modern encryption techniques fall into one of two categories - symmetric (homogeneous) and asymmetric (heterogeneous). Symmetric encryption is a system of communication whereby both parties share the same key to encode and decode a message. The Spartan generals used this method with their scytales.

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.

Data, often referred to as plaintext, is encrypted using an encryption algorithm and an encryption key. This process generates ciphertext that can only be viewed in its original form if decrypted with the correct key. Decryption is simply the inverse of encryption, following the same steps but reversing the order in which the keys are applied (Rouse, 2014).

The key can be changes and unique to each sender and receiver. ("Symmetric encryption,”) states, “There are two types of symmetric algorithms. Stream algorithms (Stream ciphers) and Block algorithms (Block ciphers).” Stream ciphers only encrypt one bit at a time. This can make this cipher faster than block ciphers, but stream ciphers have a security gap that can be harmful for specific types of attacks. These specific attacks can cause information to be compromised. Block ciphers encrypts information in blocks instead of doing it bit by bit. The size of the blocks is usually 64 bits. Triple DES and AES are the most popular symmetric algorithms that use block ciphers.

There’s two types used in encryption, there’s the public key which is used to encrypt the information you trying to send. There is also the private key which is used to decrypt the message. The public and private key is used in many things for example emails and telephones. The reason why it’s so important that these two keys are used is because the message you’re sending stays between you and the receiver, therefore the message will not get interrupted by an invader.

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

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

Encryption has been used for centuries as a way to obscure messages and hide information from prying eyes. Over the years, encryption technology has grown both more complicated and increasingly difficult to crack. One of the first electronic cryptographic technologies considered to be unbreakable was the Enigma encryption device, or simply enigma. Enigma was used by the Germans in World War II in order to communicate secretly and avoid eavesdropping. The Enigma machine was made up of a series of rotors and plugs that worked together to change the value of

Symmetric key encryption is where the key is used to not only encrypt a message but to decrypt it as well. This is also known as conventional and secret key encryption. Symmetric key encryption is rarely used due to the fact that the person who encrypts the information has to get the key to the person who decrypts the information. This is uncommonly used because if the key is intercepted by an unauthorized person, there can

Two parties each create a public-key, private-key pair and communicate the public key to the other party. The keys are designed in such a way that both sides can calculate the same unique secret key based on each side's private key and the other side's public key.

Asymmetric key system (or asymmetric algorithm; public key): A cryptographic system that uses two separate keys: one key to encrypt and a different key to decrypt information. These keys are known as public and private

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