Questions On Symmetric Encryption And Decrypt A Message

Public key and private is a type of encryption technique that can be used ensuring that the communication on the network is secured. When you sending a message to someone through the network, will need to use the public key of the receiver and the receiver will use the private key to decrypt the message. This encryption will avoid unauthorised access to the message such as reading

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.

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).

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).

To understand encryption, you must place yourself into the internet of the 90’s. At the time the internet was still new, all the data could be seen and accessed easily.The problem was that anyone could access your information and read it. This was a major issue because at that time, internet privacy was almost impossible.

Encryption that uses two keys: if you encrypt with one you may decrypt with the other

Encryption converts data from a readable form to unintelligible text. Only authorized users are able to convert the data back into a readable format. (Sayles & Trawick,

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
