The Concept and History of Cryptography

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

Cryptanalysis is the study of analyzing information systems in an attempt to learn the secluded aspects of the systems. It is used to break cryptographic security systems and gain access to the contents of encrypted messages. In The Code Book, it analyzes how people can invade your internet privacy even if you code your information. Viruses on the internet can decipher subsequent messages and programs such as the Trojan Horse can appear as a genuine encryption product, but which actually betrays

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm 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, the implications of leaked or stolen data, and a brief look into

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

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.

During World War 2 was a time of devastation. It was also a great time of innovation. One of the greatest innovations was the beginning of modern computing. During World War 2 encryption was each army’s main way of keeping war plans secure. One of the most famous encrypting machines was named the Enigma. The Enigma was a machine that took input from one side; encrypts it and sends the message to another operator who then translates it using a code book (Gladwin). Using this machine, the German’s kept nearly all the information secure from other countries. To break these encryptions, the British secret service along with many other countries started to build machines that could defeat the Enigmas encryption (Gladwin). Soon after the Germans

Abstract: The use of encryption by individuals is growing at a tremendous rate, and since 1991 cryptography issues have engulfed both the U.S. government as well as the computing industry. One of the most controversial of these issues is whether encryption should be made supremely secure to the highest-level current technology will allow, or whether a "master key" should be locked away somewhere, only to be used when absolutely justified.  Both sides of the issue have their benefits and detriments; the problem is finding the middle ground that will provide the greatest benefit to society.

In 1997 the National Security Agency (NSA) tested the Pentagon’s cyber security in an exercise named “Eligible Receiver”. Within two days of the exercise, the NSA team had penetrated the classified command network and was in complete control of network. Two years later, the United States Air Force experienced a computer breach in which huge amounts of data were being exfiltrated from research files located on airbases. “Gigantic amounts of data were being shipped out from a lot of computers in the Defense Network and from many data systems in the national nuclear laboratories of the Energy Department.” (Clarke, p. 111) File case named “Moonlight Maze”, by the FBI day-lighted two important aspects of information security.

As Paris tremble for fear from terrorist attacks that have killed 129 people, fierce blame for the massacre is falling on American whistleblower Edward Snowden and the spread of strong encryption catalyzed by his actions. The lastest deadly terror attack is leading the crypto-war as a contemporarily crucial issue. The crypto-war refers to a decades-long political battle over the legality and popularity of encryption around world. Since Snowden exposed the vast surveillance and spying done by Western governments, people have become to demand more strong encryption to shield their Internet activities from prying eyes, so encryption has been become popular rapidly. Now everyone uses encryption from e-commerce websites to terrorists. The key

“110 million Americans saw their identities compromised in 2014” Gault argues, adding that 110 million is one in every two Americans (2). With new technological inventions, such as the cloud, which allows remote access to stored information, there are “too many vulnerabilities hackers can exploit” (Gault 7). Cybersecurity has been breached due to the lack of integrity in the system. There is an acute focus on encryption in the industry with the belief that it is the key in ensuring confidentiality and ultimately, cybersecurity. Meanwhile, the industry “rarely” addresses integrity (Gault 17). Gault firmly argues that “the system is broken” because of the lack of integrity in the system. Confidentiality, while important, is not integral in preventing and providing solutions for data breach and theft. The current system solution for cybersecurity threat is dominated by a “lock-and-key system”; preventative, but once access is achieved, accessibility becomes much more effortless for others (Gault 21). Gault suggests an integrity solution that acts more “like an alarm”, a method focused on monitoring suspicious activity on online databases and platforms that then sends an alert when suspicious activity is detected. (22). Gault argues the loss of integrity is apparent in the cybersecurity industry because of the method in which prevents unauthorized access and thievery does not include elements of integrity. The

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.

As the world becomes more engrained with technology. The growing threats and security vulnerabilities propose a great concern to keep our digital information private and out of the hands of thieves, hackers, and abusers. According to David Donahoo quoted in the Liberty Journal, “The more information that is available in the cyber world, the larger the pie becomes as far as a cyber criminal is concerned.” (Menard, 2015) In other words, information security is becoming a vital intrinsic absolute when we consider the luxury our technology has brought us on a daily basis.

It was recognized that TLS 1.0, when managing different bundles, permits the accompanying parcels to utilize an IV that is the last figure content square of the past bundle. At the end of the day, an assailant who can see the encoded activity can note the IV utilized for session treat . Essentially put, a dynamic aggressor will have the capacity to assemble the Ivs for each one record just by sniffing the system. So if the aggressor can "figure" a plaintext message, he can make a theory at the session treat and check whether the figure content matches.

As global security continues to grow exponentially in response to threats of cyber terrorism, the field of computer security continues to proliferate into many adjacent socioeconomic and technologically-based areas of society. Gartner Group, a leading market research in the enterprise IT industry, has stated that the worldwide market for security software will reach $21B in 2011, rising to $15.8B in 2015 (Karjalainen, Siponen, 2011). This rapid growth of computer security is also driving the development of entirely new patents in the areas of cryptography, enterprise security management strategies, and extensive support for more advanced programming features for securing enterprise networks (Albrechtsen, 2007). The pace of development in this market is accelerating as the sophistication and variety of threats continues to also exponentially escalate (Liang, Xue, 2010).
