Encryption
In the world, where security breaches and information stealing occurs more frequently, a service offering a secure data storage is a significant factor of a security arrangement. Encryption is simply stated as the practice of systematic information scrambling, so that it can be unscrambled later [10]. Data encryption interprets data into a different form, or cryptograph, so that a person holding a secret key (i.e. a decryption key) or password can access that data. The encrypted data is known as cipher text, whereas the unencrypted data is termed as plaintext. Presently, encryption is considered as one of the most effective data security technique and is widely used by a number of organizations for the purpose of secure and reliable transmission of data containing secret information. Asymmetric encryption and Symmetric encryption are two main types of encryption techniques.

While designing a communication system, security becomes the major issue for the secure transmission of the information or data. Therefore, data encryption technique is employed in order to secure the data transmission during the communication process. Data encryption generally interprets the data into a different form, or cryptograph, so that the person holding a secret key (i.e. a decryption key) or a password can access that data. Afterwards, another issue arises later is regarding the selection of the encryption algorithm to be applied depending on the type of data.
The complexity finder mainly utilized to determine the complexity of the data to be transmitted. A threshold value is set according to which the sensitivity of the data is measured and after that the appropriate encryption algorithm is used depending on the sensitivity of that particular data. Encryption
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.
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...

Do you always feel like you have to answer to someone above you? Do you ever wonder why you feel like you are not in control of your own life? Perhaps this feeling comes because, just like medieval times, life runs within a feudal system, especially in schools. High schools mirror feudal society in their hierarchy and layout, while their values are vastly different.

For an in-depth defence approach, case study provides a series of things that describe about what is working nowadays for a secure data.
Encryption: - Data encryption is the best way to reduce risks associated with misplaced, lost or stolen data.
The study [1] shows that there are some Implications for data breaches. While data loss and data leakage are both serious threats to cloud computing, the measures to mitigate one of these threats can trigger the other. Encrypting the data may reduce the impact of a data breach, but losing the encryption key, means losing the data as well. Also, keeping offline backups of the data to reduce the impact of a catastrophic data loss, will increases the exposure to data breaches.
This is the information age. There are financial and corporate information, research and analysis, trends have lead the trend and military intelligence. Information classified as confidential, sensitive and critical. There are gleaning information extraction and automated tools. There are management solutions, such as content management, knowledge management and document management, information management collected for. There are different mechanisms for storing information storage. Finally, information security, there are tools and techniques. In this paper, three important types of security information we need to discuss, such as security information from hackers, during transit to ensure that information and the protection of information stored in the system can be lost or stolen. Finally, a brief about wireless security has been described here. The Internet has become the information superhighway. Evolving Internet and related technologies have allowed companies to communicate in new ways with all types of people and strategic organization. Over the years, there have been increased after the distinctive features of Internet connection. As needs change, the more powerful the service of humanity encountered, faster connections, and what can be done in the need for more flexibility. Initially, the service, such as a simple POP3-based email and Web access is the extent of an Internet connection. Today, we have a site-to-site virtual private network (VPN), clients and home users VPN, streaming media, Web-based training, wonderful Internet applications, e-commerce, and business-to-business extranet. Therefore, the development of the Internet to meet the needs of a variety of advanced human society. On the home front, fr...
1. There are many awards for children’s literature, but some of the major awards are The John Newberry medal. The Newbery Medal was named for eighteenth-century British bookseller John Newbery. It is awarded annually by the Association for Library Service to Children, a division of the American Library Association, to the author of the most distinguished contribution to American literature for children. Another award is The Caldecott Medal it was named in honor of nineteenth-century English illustrator Randolph Caldecott. It is awarded annually by the Association for Library Service to Children, a division of the American Library Association, to the artist of the most distinguished American picture book for children.

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.
Sushi and Sashimi have been around for quite some time now but back then it was a little different. Sushi was originally a way of preserving food; fish would be covered in rice to ferment; this kept the fish fresh for a longer period of time.. Sashimi is an art in the eyes of japanese cuisine; Sashimi is essential raw food (mainly fish), thinly sliced and served just like that. Both Sushi and Sashimi are similar but which is more traditional, more original?
Epistemological beliefs refer to knowledge and understanding and there are two ways of knowing, which are called separate knowing and connected knowing. Separate knowing is a critical thinking approach, whereas connected knowing is an approach where an individual attempts to understand ways in which other people think and use this technique to understand their point of view. This study will look at the effects of students’ personal epistemological beliefs, - along with separate knowing and connected knowing - and their approach to thinking and learning and whether or not the students’ attitudes can influence academic performance or not. Previously, much research has been done where researchers have studied the way in which epistemological
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:
“Time Complexity of an algorithm signifies the total time required by the program to run to completion.The Time complexity of algorithm is most commonly expressed using the big O notation”.
