Protecting data through cryptography from unauthorized eyes is a high priority for organizations that store personal information. Cryptography is the process of hiding the real meaning of a message through a pre-determined code that is only known to the person encrypting and decrypting a message. Different forms of cryptography can be seen in our everyday life from the word puzzle in daily newspapers to secretaries writing in short hand. Cryptography has been around since the time of the Egyptians and has made many advances through the years.
The first sign of cryptography was documented on Egyptian scribes where non-standard hieroglyphs were used on clay tablets. (Whitman, 2011, p. 351) The Egyptians were the first documented people to use cryptography in 1900 B.C. (Whitman, 2011, p. 351) With cryptography surviving for so many years it is no wonder that it is still being used today to hide the real meaning of messages. There have been many advances since the time of the Egyptians but the purpose is still the same which is to keep information from unauthorized individuals.
With more personal data being stored on information systems that are accessible through the World Wide Web the desire for hackers to decode encrypted data has increased. Since there is additional interest in decoding encryption the cryptographers need to constantly develop harder cyphers for individuals to solve. Hackers steel personal information from personal computers or databases storing personal information for organizations than use the information to steel the identities of others. When personal information is sent over the internet through a network that is not using cryptography to encrypt the data it is very easy for the data to be view...

...o keep un-authorized individuals from seeing the information they are sharing with others. Cryptography like technology is always going to be changing to try and keep one step in front of hackers. With so many organizations losing sensitive information to hackers it is important to continue to think outside of the box for new ways to secure data through cryptography.

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.
Encryption is the most powerful way to secure information by protecting it in the occurrence of theft, loss, or unauthorized access. It scrambles your data by requiring the receiver to have a secret key or password which would allow them to decrypt it. Web browsers indicate encrypted security techniques by showing a “lock” icon in the status bar. Webpages for online shopping will have either “http” at their beginning of the web address or a “lock” icon on the page. Email services should be protected by antivirus software. These
Encryption is a strategy for changing data on a computer in a manner that it gets to be distinctly incomprehensible regardless of the possibility that somebody can access a PC with individual information on it.
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.
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.
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).
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.
...tal part of lives just like privacy. Using cryptology provides mechanisms through a digital signature. 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.
Cryptography was first used long before the invention of computers. One well-known system was attributed to the reign of Julius Caesar (Klein ix). Another example is the famous Zimmerman telegraph, which was sent from Germany to Mexico during World War I (ix). In a more modern setting, cryptology was mainly used by the government until the late 1970s (Simpson 1). This is largely due to the fact that computers were too expensive, so not many households or businesses had them (1). However, after the computer revolution, cryptology became more public, especially in the business industry where there was a greater need to secure things like transactions (1).
...M and the US National Security Agency. It was previously the most dominant type of encryption, but it is now being taken over by AES (Advanced Encryption Standard). Since data encryption standard, only took on a 56-bit symmetric key encryption, AES uses three key sizes, 128, 192, and 256 bits. When personal computer users want to encrypt email or other documents, they go to Phillip Zimmerman?s "Pretty Good Privacy" software. This software allows you to digitally sign a message, which verifies to the recipient that you are the sender and that no interfering is involved.
The internet allows people to communicate sensitive information, and if received in the wrong hands can cause many problems for that person. Cryptography is the study or science of techniques of secret writing and message hiding. Cryptography constitutes any method in which someone attempts to hide a message, or the meaning, in some medium. One specific element of cryptography is encryption, which hides the data or information by transforming it into undecipherable code. Encryption uses a specified key to perform the data transformation.
Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
B. A5/1 - It was created in 1987 is used to encrypt over the air communication and is hence defined for GSM use, serving over 7 billion people. The original cipher was meant to have a key length of 128 but due to negotiations between the British and the Germans involved in it the length was reduced to 56, reducing its security considerably. Its algorithm was reverse engineered in 1999 and has been subject to various attacks and in recent times the decryption can also be done in real-time, which means the security is very
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:
The Internet is a connection of computers across the world through a network. Its origin dates back to the 1960s when the U.S Military used it for research, but it became more available to the public from the late 1980s. The World Wide Web was created in 1989 and browsers began appearing in the early 1990s. Over the last 24 years, the Internet has enabled people to shop, play, do research, communicate and conduct business online. It has also become cheaper and faster in performing different tasks. As much as the Internet has done immeasurable good to society, it has also dominated people’s lives and brought with it an array of cybercrimes. According to Nicholas Carr in his book The Shallows: How the Internet is Changing the Way we Think, Read and Remember (Carr, 2010). He debates on whether the Internet has done more harm than good. People use the Internet daily to exchange accurate information and constantly personal data such as credit cards, passwords and Social Security numbers are travelling through the network from one computer to another. With security measures put in place on the Internet, personal information remains confidential. But unfortunately, criminals have adapted to innovations in technology, and today, more people are increasingly becoming victims of cybercrime. The Internet has had profound effects on the public, both positive and negative. In this paper we will examine how access to personal information has led to an increase in online and offline crimes. The essay will particularly focus on ecommerce and hacking.
