The History Of Data Encryption Technology Essay

Confidentiality is the protection of information from unauthorized access. This is the assurance that information provided has not been made known to unauthorized persons, processes or devices. The application of this security service suggests information labeling and need-to-know imperatives are core aspects of the system security policy. Information, in today’s world, has value and everyone has information they wish to keep secret. Information such as credit card details, trade secrets, personal information, government documents, and many more. It was stated (Securitas Operandi™, 2008) that, we are bound to keep many secrets – corporate, staff, and personal secrets. We must keep this confidential information under wraps and earn the trust of employers, colleagues, and regulators every day. Mechanisms to enforce this include cryptography, which is, encrypting and decrypting data, access controls such as

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

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).

Business firms ,state firms are afraid about the threat posed by hackers to data at rest.Data encriyption

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).

In today’s IT world every organization has a responsibility to protect the information and sensitive data they have. Protecting data is not only responsibility of security and IT staff but every individual is involved in protecting the information. The risks to information security are not digital only, but it involves technology, people and process that an organization may have. These threats may represent the problems that are associated to complex and expensive solution, but doing nothing about these risks is not the solution.

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 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,

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

In this paper we will look at defining the problem of data security and public administration. The reader will see the evidence gathered to get a better understanding of the problem of not securing data when sending it. The reader will learn different alternatives to how they can ensure the data is secure.

Digital security, which can likewise be alluded to as data innovation security for the most part takes a gander at PCs, systems and information from an unidentified access.

a significant amount of data security breaches are due to either employee oversight or poor business process. This presents a challenge for businesses as the solution to these problems will be far greater than simply deploying a secure content management system. Business processes will need to be examined, and probably re-engineered; personnel will need to be retrained, and a cultural change may be required within the organization. These alone are significant challenges for a business. A recent example of what is probably unintentional featured an Australian employment agency’s web site publishing “Confidential data including names, email addresses and passwords of clients” from its database on the public web site. An additional

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:

3DES (Triple DES): An enhancement to the original DES algorithm that uses multiple keys to encrypt plaintext. See also DES.
