Data Encryption The definition and importance of data encryption Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers must protect the customers’ personal information from hackers or competitors. They also have many business files or contracts that need to be strictly protected. Without data encryption, these important information may fall into wrong hands and be misused by others. Besides, data encryption may be used to secure sensitive information that exists on company networks, or create digital signatures, and help to authorize in business. No one should underestimate the importance of encryption. A little mistake in encryption may make sensitive information revealing, or even result in illegal and criminal accuse. Data Encryption is from the cryptography science, which includes coding and decoding of message to protect the safety. Development computer technology makes the encryption even more complicated. The ability for people to break codes is increasing, so are the ability to guard the codes. Many encryptions are available now. They were developed by some hi-tech company and sold, or you can choose some free service. Actually, when you are using the web browsers, emails, or even the basic system, your information has been automatically encrypted.

What is encryption? Encryption is a technological technique that protects and secures the transfer of plain text information between two sources through the use of the internet. This is done by rearranging the text using a mathematical algorithm that renovates the message into an indecipherable form, which can only be unlocked and translated with a use of a key. The strength of the encryption key is measured by its length, which is determined by the number of bits and by the type of encryption program.
Homomorphic Encryption allows access to highly scalable, inexpensive, on-demand computing resources that can execute the code and store the data that are provided to them. This aspect, known as data outsourced computation is very attractive, as it alleviates most of the burden on IT services from the consumer. Nevertheless, the adoption of data outsourced computation by business has a major obstacle, since the data owner does not want to allow the un trusted cloud provider to have access to the data being outsourced. Merely encrypting the data prior to storing it on the cloud is not a viable solution, since encrypted data cannot be further manipulated. This means that if the data owner would like to search for particular information, then the data would need to be retrieved and decrypted a very costly operation, which limits the usability of the cloud to merely be used as a data storage centre.
Modern cryptography is far more complicated. It consists of long mathematical formulas that to most people looks like total gibberish. However, these formulas turn a normal sentence into undecipherable code. Modern encryption codes are used daily throughout our daily lives For example they are used widely throughout he Internet for security purposes.
Today’s businesses and organizations need privacy. They need to keep their employee’s information, trade secrets, financial records, and many other sensitive documents that cannot be shown to the public. To do this, these organizations use encryption. Encryption is using an irreversible program to turn a file into gibberish. To translate the gibberish back to the original contents of the file, you must use a decryption program and provide a password. This is so the program can decrypt the file correctly. This encryption is what prevents cybercriminals who happen to get a hold of any files from looking at file contents. To the cybercriminal, encrypted files are completely useless unless he can figure out how it was encrypted. In order to decrypt the file, the cybercriminal must first find a series of steps that can decrypt the file over and over again: an algorithm.
Each day, billions of people worldwide depend on the security of digital systems. From medical history and test results at a hospital, to financial information and account statements at a bank, or social connections and personal messages on a smart phone, nearly every facet of a person’s life has some component of personal data associated with it that is stored on a computer. Furthermore, new forms of personal data to collect are being identified, gathered, analyzed, and stored all the time. This growth in the collection of personal data is so immense that the amount of digital data in existence approximately doubles every two years, and large companies are responsible for creating about 80% of this data increase (Gantz & Reinsel, 2011).
On 5 October 2009, computer equipment from a network data closet was stolen from BCBST. The items stolen were 57 unencrypted hard drives which contained over 300,000 video recording and over one million audio recordings. According to Whitman & Mattord (2010), confidentiality, integrity, and availability makes up the C.I.A triangle which is the basis of Committee on National Security model for information security, an industrial standard, (Whitman & Mattord, 2010). Confidentiality can be a synonym for encryption but also means only the people with the correct permission can access the information. One of the major security issue is the hard drives were not encrypted. The hard drives should be encrypted to prevent people from reading the information the computer. Software can be purchased which will encrypt files on hard drive with such as Folder Lock, SensiGuard, Secure IT, and more. There are open source encrypting software which are free for use which could have been used. If the hard drives were not needed, the data should hav...

This signature is inserted using a key (that only the writer of the email possesses) whilst a timestamp binds itself to the document. This type of cryptography is used to control access of security installations or pay-per-view television channels.
Source B argues that encryption prevents crimes from being solved, which includes a father of six who was shot dead and the killer is now on the run (Source B). The article describes that there were two smartphones, one phone running on Apple’s operating system, and one on google’s Operating system. These phones seem to hold the answer to the crimes, but they can not be unlocked because the phones have been encrypted so not even the companies can unlock them. By having these phones encrypted, this could lead to this crime not being able to be solved and six kids not knowing who killed their father. Encryption adds an extra, very difficult, step that hinders the government's ability to be able solve crimes quickly and efficiently.
Computer science is a vast field that includes nearly everything relating to computers. Everyday there is information transmitted all over the Internet. Pictures are uploaded, transactions are made on thousands of online retail websites, and banking transactions take place everyday on the Internet. All of these transactions have created a need for secure communications. People wish to keep things like banking, medical, and political information from the eyes of unwelcome parties. This has created a need for cryptography. Cryptography is the science or study of the techniques of secret writing, especially code and cipher systems, and is used by everyone from the average citizen to the government and military.
Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.
Data encryption refers to the transformation of data into a structure that makes it unreadable by anyone without a secret decryption key. It ensures that messages can be read only by the planned recipient. Encryption is the procedure of obscuring information to create it unreadable without special information. Only organizations and individuals with an abnormal need for secrecy have actually made good use of it. Nowadays, encryption is one of the most important technologies for maintaining your privacy and the security of important information. This helps out greatly especially when E-Commerce is being used.
Cryptography is the common term given to the art and science of keeping the text messages secret. It is not the purpose to evaluate in detail any of the mathematical algorithms that are used in the cryptographic process, but instead to provide a general view of the process and its uses. To introduce briefly one of the fundamental building blocks of all network security, one must know the process of encryption and decryption. A process that transforms the given information (the plaintext) into a seemingly meaningless form (the ciphertext) using a mathematical algorithm and some secret information (the encryption key). The process of decryption revokes this transformation using a mathematical algorithm, in conjunction with some secret value (the decryption key) that reverses the effects of the encryption algorithm. An encryption algorithm and all its possible keys, plaintexts and cipher texts is known as a cryptosystem or cryptographic system. Figure 4 illustrates the process.
Privacy is the ability to maintain what or who can access and see your personal content and information. With that, the idea of privacy is different amongst different cultures and countries, while they all differ, they share common characteristics. The act of sharing ones own personal information is decision one must make on their own. Privacy is a right that all people should have and the government has the responsibility of maintaining that right. Data such as personal emails, bank details, medical records, and passwords need to remain safe and secure to ensure privacy is not invaded.
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
You might be asking yourself what cryptology is, cryptology is the study of codes, or the art of writing and solving them. To understand cryptology, you need to understand encryption, because they are related. In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it. In cryptology, a code is a method used to encrypt a message that operates at the level of meaning; that is, words or phrases are converted into something else.
