When it came to Cryptography, the idea of information security is what originally lead to it. In different words, Cryptography is the protection and security of all information. This is going to involve encryption as well as decryption of all messages. Encryption happens when you are converting plain text into what you would call cipher text. Decryption is when you are going to gain the actual original results of the text that was encrypted, (Jevons, 1974). Although cryptography provides confidentially within documents, it also consists of providing authentication, integrity, as well as non-repudiation. When it comes to the crux of cryptography, it is going to mainly revolve around the secrecy of all keys that are being used to encrypt as well as decrypt. Another factor involving this is the actual key strength, it is going to make it difficult in order to perform a brute force amongst the plain as well as cipher text in order to retrieve the key. There are numerous and a wide variety of cryptographic algorithms that have been suggested, (Jevons, 1974).
Within the globalization time, cryptography has become way more popular as well as powerful; in fact cryptography is important to several areas such as mathematics, computer science, networks, etc. The overview as well as comparison that is between both of the factors pertaining to the RSA cryptosystem and the elliptic curve is going to be discussed. Both of these are focused on either sending or receiving messages. Basically the basic and most novice theories of the RSA and elliptic curve are going to be explored.
When it comes to both of the RSA cryptosystems and the elliptic curve cryptography, they are quite similar but the elliptic curve is well more advanced and difficult. T...

...iffie-Hellman keys are more vulnerable when it comes to a smaller subgroup attack. With practice, this issue is going to arise for both sides of the parties within the Static mode as well as for the receiver during the Ephemeral Static mode. If you use what you would refer to as a weak random number that is generator without the complete random output, would make the sender and receiver more vulnerable to the authentication of the communication between both of the sender and the receiver. As the final result, it is going to be vulnerable to the “Man –in-the-middle” attack, (Frederick, J., 2001). This is going to defiantly allow any attacks to imposter or pretend to be the desired party in which the sender is sending the key exchange. Once this is authenticated to each party, this person is going to be able to decode any traffic that is sent amongst the two parties.
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
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.
PKC is the enabling technology for all Internet security and the increasing use of digital signatures, which are replacing traditional signatures in many contexts. However, RSA is better than PKC because RSA doesn’t need digital signature. As a result, the RSA algorithm turned out to be a perfect fit for the implementation of a practical public security system. In 1977, Martin Gardner first introduced the RSA system. After 5 years, company RSA used secure electronic security products. Nowadays many credit companies of all over the world use the RSA system or a similar system based on the RSA system.
Privacy and security issues have become one of the top concerns among computer users in today’s market. It has become a game of survival of the fittest in protection of your security. The only true way to defend yourself is knowledge. You should prepare your self against hackers, spammers and potential system crashing viruses and web bugs. Lets focus on how you can protect yourselves from the would be thieves.
Privacy does not have a single definition and it is a concept that is not easily defined. Information privacy is an individual's claim to control the terms under which personal information is acquired, disclosed, and used [9]. In the context of privacy, personal information includes any information relating to or traceable to an individual person [ 1]. Privacy can be defined as a fundamental human right; thus, privacy protection which involves the establishment of rules governing the collection and handling of personal data can be seen as a boundary line as how far society can intrude into a person's affairs.
We are living in world that is growing in technology. Technology is evolving so rapidly, especially in ways that allow us to store personal information. For example, we can look up a purchase with no receipt at a retail store with a swipe of a credit card. Another example, we could go to the doctor and the nurse can print out a copy of all our health records that are stored in the computer by just typing in our full name. Although this may be a way to make things easier for us, it is also a way for people to take our information without permission and do what they please with it. People can hack into the database of retail stores and steal account numbers and people can just say your name and get your health history if the nurse does not ask for a form of identification. Information privacy is a growing concern for Internet and data users. In a report Protecting Privacy in an Information Age: The Problem of Privacy in Public, researched by Helen Nissenbaum of Princeton University, she states:
Benjamin Franklin once said: “ They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.“ Today, we may agree or disagree with Franklin’s quote, but we do have one thing in common: just as Franklin, we are still seeing freedom vs. security as a zero-sum game – one where one can gain only at the expense of another and where the two cannot possibly coexist. However, this is not necessarily the case. There does not have to be necessarily a trade-off between privacy and security; the proper balance is the one where neither security nor privacy suffers from both of them being present in our daily lives.
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.
My knowledge has grown over the past six years, outwith the areas of learning offered by school courses, and I see this course as an opportunity to gain new skills and broaden my knowledge further. My main interests are varied, including communications and the internet, system analysis and design, software development, processors and low level machine studies. I have recently developed an interest in data encryption, hence my active participation in the RSA RC64 Secret-Key challenge, the latest international de-encryption contest from the RSA laboratories of America.
...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.
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.
All our classical computer cryptography methods are basically based on some mathematical calculations which are quiet easy to implement in one direction but very difficult to process in the other direction. As RSA(Rivest-Shamir-Adleman) algorithm which is one of the first practicable and most famous public-key cryptosystems, RSA, is based on the technique of factoring large numbers which makes it secure. Difficulty in factoring increases with number of digits in RSA key. For example, a 128 digit number would take millions of years to factor with current computers.
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:
This paper is going to discuss wireless security from a broad view where I will go into why exactly wireless security is so important especially today as the ways in which we are communicating is changing dramatically. From there I will discuss the multiple wireless securities that are available to give a better understanding of the options given. Then I will go into why exactly not protecting your wireless can be so dangerous with some descriptions on the most dangerous wireless attacks out there today. Finally I will then discuss how we can better prepare for these types of attacks with a synopsis on several effective security methods that will help to ensure data is securely passed and kept hidden.
