ABSTRACT
In this research paper I want to shed light on encryption. After careful research it becomes clear that encryption has been around for centuries and used in various ways. There are two distinct methods of encryption: Public Key and Private Key. Each comes with its own set of pros and cons but Private Key is the more widely used method. Laws have been put into place to sanction the use of encryption products and devices. Information has been gathered from several different sources to also explain how encryption has impacted the past and how it will continue to shape our futures.

Private Key encryption is somewhat complex because of how the key is exchanged between parties. Private Key encryption, also known as symmetric encryption, is where one key will encrypt and decipher information. The benefit of this method is that the process is very fast as a single key is used for both ends of the encryption chain. The problem is protecting the key from others as a single point of potential security failure. Key management is a primary concern when using private key encryption. (Snyder, 2012) In private key algorithms a combination of letters and numbers are used along with multiplication and division to confuse the hackers because they don’t know exactly what is being used to encrypt the …show more content…
One in particular is AES, Advanced Encryption Standard. It is the most commonly used and widespread algorithm to date. (Lindsay, 2011) AES, along with other current encryption schemes, have never been directly broken. With the modern advances in technology it is crucial to have a standard that has proven to be more than reliable and has stood strong in the lines of fire against hackers trying to break the encryption method for whatever reason. Private Key encryption is heavily relied upon to day for one simple reason, it’s hard to duplicate keys when you don’t know exactly what it is that you are trying to duplicate. Imagine how hard it is to break the passcode of someone’s iPhone and how it seems no matter what combination of number you put into the phone, you still can’t manage to get through. Private Key encryption is even more frustrating and difficult than that is, to
In July 2015, many of the world’s high ranking cryptographers published that the loss and destruction induced by adopting a key escrow system 20 years ago would be even more serious, that would be very hard to identify security weaknesses that could be misused by
The RSA cryptosystem, imagined by Ron Rivest, Adi Shamir, and Len Adleman , was pitched in the August 1977 issue of Scientic American. The cryptosystem is generally ordinarily utilized for giving security and guaranteeing legitimacy of advanced information. Nowadays RSA is sent in numerous business frameworks. It is utilized by web servers and programs to secure web traffic, it is used to guarantee security and legitimacy of Email, it is utilized to secure remote login sessions, and it is at the heart of electronic Visa installment frameworks. In short, RSA is much of the time utilized within provisions where security of advanced information is a worry.
In the rapidly developing field of computer science, there is no more controversial issue than encryption. Encryption has become a highly contested issue with the broad use of global networks including the Internet. As more and more sensitive documents are being placed on computer networks, and trusted information is being sent from computer to computer throughout the world, the need for encryption has never been greater. However, the effects of encryption on our lifestyle and the government's role in encryption has been (and will continue to be) debated for years to come.
RSA encryption is the foundation of public key cryptography security products. For example, credit card companies use the RSA algorithm for customers’ individual online WebPages. The credit card companies publish a big number on WebPages, which is made by big prime numbers using the RSA algorithm. Since neither computers nor people can factor such big numbers, the RSA encryption system has secured many customers’ information.
In 1995, Leonard N. Foner, a researcher at the MIT Media Lab, wrote “Cryptography and the Politics of One’s True Name,” an essay discussing the morality and legality of cryptography in both the public and private sectors. In this essay, he argues that strong cryptography is essential to the privacy of secure exchanges of money and information. While Foner’s essay was certainly relevant when it was written, the advancements in technology made since then as well as the dramatic increase in dependency on cryptography for everyday aspects of life make his essay more relevant than ever. When emphasizing the value of cryptography, Foner explains in great detail how cryptography works, which helps the reader understand the importance and impact of
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.
Encryption is a key solution to mitigate potential corruption without fault. Many resolutions to problems are large enough to ensure that the whole company is in complete submission to the security regulations. Data encryption enables a company to reach a high level of security with ease and low cost. Data encryption can also shield confidential information stored on a computer
If organisation’s sensitive data and intellectual property resides on public cloud then it is strongly advisable to implement strong encryption techniques. The threat of data tampering is at its highest when data is being processed in the cloud. Essentially, this is because when data are
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.
Recently, James Clapper, the director of National Intelligence, strongly blamed Edward Snowden, NSA whistleblower, for leading the development of user-friendly and widely available powerful encryption. Due to the Snowden revelations, the outbreak of commercial encryption has accelerated during last seven years. He said that the shortened timeline has accompanied a serious implications on their ability to accumulate information, especially against terrorists. He argued that the maturation and installation of commercially available encryption was accelerated, due to the revelation of the leaks. Technologists have been continuously studying a way to strengthen encryption. However, Snowden’s revelations about the pervasiveness of mass surveillance
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.
For thousands of years cryptography and encryption have been used to secure communication. Military communication has been the leader of the use of cryptography and the advancements. From the start of the internet there has been a greater need for the use of cryptography. The computer had been invented in the late 1960s but there was not a widespread market for the use of computers really until the late 1980s, where the World Wide Web was invented in 1989. This new method of communication has called for a large need for information security. The internet allows people to communicate sensitive information, and if received into the wrong hands can cause many problems for that person.
Encryption plays a big role with the safety now in day because everything is now done digitally and it helps it be more confidential. This prevent “hackers”, well it’ll be difficult for them to open the gateway to get all the confidential information someone wanted to hide. The disadvantage is that drug dealer and sex trafficker can make money by making the encryptions and that’s where they have people wire the money and it’s untraceable unless cracked. Encryption is playing a big role in the world because people use it for protection in their important usage or for government purposes and others use it for the dark web to transfer their illegal money to be untraceable.
