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

Encryption is the process in Cryptography to secure data. It encodes the data or information using a key in which way only the person can decode it who has the decode key. It improves the security of data or messages or files by making it un-understandable by normal view, so that it can be understand by person only who have the right decryption key.

Validation methods, for example, Key Administration, Two Factor Confirmation, and Mechanized Key Administration give the capacity to encode and unscramble without a unified key administration framework and document security. There is ceaseless research incident to fortify these verification systems.

When developing an information system that will hold private and vital informations, it is necessary to think of protecting those data. The security of information is concerned with the following areas: confidentiality, data integrity, availability, authenticity, non-repudiation and risk management. All these security aspects, may be affected by purely technical issues (e.g., a malfunctioning part of a computer or communications device), natural phenomena (e.g., wind or water), or human causes (accidental or deliberate).This report will give a definition of these security issues with examples to illustrate them.

Since the computer was invented the evolution of technology has grown into culture and has been the central of communication since the early 1980s. In order to understand the meaning of encryption and why it is so important, you have to understand why the computer was created and how inventors have continuously improved computer hardware devices. The computer was first invented to calculate numbers and help scientists with different mathematical equations. Then during the world war I, and world war II, Germans were using these computers to encrypt messages over morse code and complicated algorithms. However these algorithms of encryption were easily cracked by United States cryptographers. Over the war many encrypted messages were broken and the German military lost substations, overall control of the war; and eventually surrendering. Safe to say that encryption devices has been a necessity for transmitting data securely and in today’s society personal containment (Crayton & Culp, n.d.). Over the next five decades inventors, of all nationalities, have worked to improve encryption hardware devices from the internal architecture, removable storages, networking devices, and the overall networking security module.

The goal of our research paper is to provide a concise analysis on data security and privacy protection issues pertaining to data and databases as well as the current advancement/ breakthrough made and achieved in regards to database security and privacy concerns. We will also discuss in this paper some current solutions in the security market. First, we looked at the a trusted database model which makes it possible to shield database with absolute secrecy to benefit trusted equipment presented on the side of server and made to work at the charge of any cryptography which permits private data handling on a simple device.

A database’s confidentiality associates with the protection of data information from being disclosed to unauthorized parties. Users who are given access to the data should be able to view certain data according to their given authority. For example, an employee should not be able to see the salaries of their managers however the managers should be able view an employee’s criminal history. A loss of confidentiality means that the data or system is unsecure and unauthorized personnel have the ability to transfer or leak any unsecured data. A method to thwart this threat is through data encryption. This security option uses mathematical algorithms to render a network message unreadable to unauthorized users. The encoding of the data becomes protected and the only way to gain access to the data is through a decryption key. Encryption prevents unauthorized users from reading encrypted data and prevents data leakage.

Encryption is a very important aspect of our daily lives. Everywhere we go and everything we do now involves some sort of encryption technology. From turning on our cars to using a card access to gain entry to our workplace, encryption is there. More specifically, encryption in communication is a vital component to everyday life. Without encryption, our lives would be much different and unsecure.

Asymmetric cryptography is based upon a key that can be made transparently accessible to the general population, yet still give security.

Encryption is the process of ensuring that data is encoded in a format that only computers with particular decoders will be able to decrypt the information and as a result get the intended receiver of the information. For example the FBI values secrets and the mails they send are always encrypted and no one can read the information until a particular machine or tool is required to be able to understand what the mail mean.

Key is an important requirement in encryption process.pk is denoted as public key and sk as private key [5]. Encryption process is denoted by Enc and decryption process is denoted by Dec. Given a plaintext m and key k, encryption is defined as Enc (m, k) and Decryption is defined as

For information to be private and secure, encryption is used. A piece of information can be encrypted by changing each of the characters in the data to something different. The encrypted information can then be decrypted to find out the original information. It is important for information to be encrypted so that only the person that has sent and the person receiving the information can see it. Without

Thus, it is essential that computational techniques are performed so that the requirements of information protection are met. In this scenario are presented the two basic types of encryption, symmetric or private key and public key or asymmetric.

It’s evident that technology has massively evolved over the last century, bringing new services on the table, such as communicating with people all over the world, ecommercing or generally doing things that would take a lot of time with the press of just a few buttons. A new world unfolded since tons of information was being shared on the Internet. That, led to the need for data encryption and it didn’t take long for cryptographic protocols to be created, obfuscating data so that no eavesdropper would be able to see what was being

Cryptography is the science of study and practice of various techniques related to secure communications by means of adversaries. The study deals with analysis of various techniques and constructing protocols to block the adversaries. Aspects like non-repudiation, integrity of data are important to modern day cryptography. Modern day cryptography utilizes Computer science, and mathematics disciplines and its applications span for the usage of ATM cards, distribution systems encryption and in the areas of electronic commerce (1, 2).
