Symmetric key encryption is also known as shared-key, single-key, secret-key, and private-key or one-key encryption. In this type of message encryption, both sender and receiver share the same key which is used to both encrypt and decrypt messages. Sender and receiver only have to specify the shared key in the beginning and then they can begin to encrypt and decrypt messages between them using that key. Examples include AES (Advanced Encryption Standard) and TripleDES (Data Encryption Standard).

and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation

How companies use cryptography How penetration testers can also use cryptography Tools, Techniques and Attacks Academics discusses history of encryption. Academics simply encrypt or hash, why aren't people using hashing more? Professional is just, encrypt or not, hash or just verify Section 1-2 Topic: Key Concepts of Cryptography: PKIS & Encryption Learning Objectives: Cryptography is one of the most underrated courses of study in the industry. Of those who do study it, issues with comprehension

What is asymmetric encryption and why do we need it? Asymmetric encryption is also known as public key encryption where there are two keys, a public key and a private key (Ezeobika, 2010). One key is used to encrypt and the other to decrypt (Hitachi ID Systems, Inc., 2013). Asymmetric encryption allows users to send secret messages by encrypting with the public key that belongs to the recipient (Hitachi ID Systems, Inc., 2013). Only the recipient will be able to decrypt the message because only

Network Assignment #2 1. Compare Peer-to-Peer against Client server Networks. Discuss (briefly) the differences using the following factors: a. Security: Peer-to-Peer does not provide the security available on a client/server network but a client/server has its resources centralized which mean resources and data security are controlled through the server. b. Complexity: Peer-to-Peer only required two computers connected together however client/server required special

considered for the encryption of all sensitive data being transmitted over the Internet. There is symmetric encryption and asymmetric encryption. It is the intention of this paper to describe both methods and give an opinion on which method to use to secure the sensitive date. When a symmetric encrypted key is used, both parties share the same key to both encrypt and decrypt data. Since symmetric encryption's use-case is to share information between users, each has to posses a shared key. Although a

between symmetric and asymmetric encryption. SYMMETRIC ENCRYPTION This is also referred to as Secret Key Encryption. In this type of encryption a secret word which could either be a number, word or string of characters is applied to the text of a message to change the content in a particular way such as shifting each letter by a number of places in the alphabet but both the sender and the receiver should know the secret key in order to encrypt and decrypt all messages that use this key. Symmetric

significance. In this seminar work, we discuss the applications of encryption techniques in database security. This is an area of substantial interest in database because we know that, the use of database is becoming very important in today’s enterprise and databases contains information that is major enterprise asset. This research work discuses the application of various encryption techniques in database security, and how encryption is used at different levels to provide the security.

INFORMATION SECURITY IN THE DIGITAL WORLD NAME Abstract Information security is the process of detecting and preventing unauthorized users access to your network, computer, and ultimately your personal information. Information security is huge and many casual users do not even think about it, or if they do, only as an afterthought. This is one of the worst things that you can do in this day and age especially with the abundance of
