Rivest, R.L., et al [1977]: An encryption method was presented in the paper with the then relatively new and novel property that publicly revealing an encryption key did not thereby reveal the corresponding decryption key. This had two important consequences: 1) Couriers or other secure means were not needed to transmit keys, since a message could be enciphered using an encryption key publicly revealed by the intended recipient. Only he could decipher the message, since only he knew the corresponding decryption key. 2) A message could be “signed" using a privately held decryption key. Anyone could verify this signature using the corresponding publicly revealed encryption key. Signatures could not be forged, and a signer could not later deny the validity of his signature. This had obvious applications in “electronic mail" and “electronic funds transfer" systems. Their encryption function was the only candidate for a “trap-door one-way permutation" known to the authors. However, they conceded that it might be desirable to find other examples, to provide alternative implementations should the security of their system turn out someday to be inadequate. This technique though, remains the most popular technique still in use. [1]
Boneh, D., [2000]: The attack on RSA cryptosystems is the science of breaking the encoded data. The attacks toward the smart IC card device of the RSA cryptosystem can be classified into two basic categories as the traditional mathematical attacks and the implementation attacks. The traditional mathematical attacks are algorithms modeled as ideal mathematical objects. Attacks of this kind are typically generalized and mostly theoretical rather than operational. The physical implementation attacks strategies ar...

...s are a vital component of Information Security as a means of securing modern networks against would-be attackers by providing data integrity, encryption and authentication to network traffic at the transport layer. Sensitive information, such as banking details, that transverses networks will most likely do so through an encrypted tunnel provided by the cryptographic protocol; it is thus imperative that both the protocol itself is secure and the applications use of the protocol is correct and sensible. It is clearly apparent that it is no longer possible to be an expert within Information Security but rather an expert in one of its subsidiary fields. Cryptography is a field of great interest both academically and economically and the intelligent use of cryptography will lead to improved user satisfaction and safety when using networks to perform confidential tasks.

It is the discovering we just described that allowed Shannon to publish in 1949 his paper Communication Theory of Secrecy Systems in which he developed the concept of a Cryptosystem. To understand the revolutionary nature of this publication, we are now going to describe what cryptography was before its publication.
This lecture was given by Dr. David Mirza Ahmad one of chief mentors of Subgraph, which is a open-source security start-up based out in Montreal. The talk was based on Kerchoff’s principle which states “the security of any cryptographic system does not rest in its secrecy; it must be able to fall into the enemy’s hand without inconvenience” [1]. The kerchoff’s principle underlines the fact that free software should be having reasonably good security. This fact is well understood by the world of cryptography because cryptography is a black-box where you never know what is happening inside it.

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.
Progressive technological development has paved the way for the ever increasing addition of multiple disparate devices. Devices which have the capability to connect to each other over a network affording them the ability to communicate with ease. Unfortunately the improved proficiency for communication carries with it a negative impact on information security. This detriment comes through the increased possibility of data loss and vulnerability exploitation. In this paper, we will seek to define one such measure to ensure security; by utilizing the Trusted Platform Module (TPM). We will also explore the strengths and vulnerabilities of the Trusted Platform Module as well as attacks against the TPM both in terms of hardware and software.
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.
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.
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
waves go through most dividers effortlessly. This element requires the utilization of encryption. Wired Equivalent Privacy (WEP) was the principal endeavor at giving security on remote connections. Nonetheless, Borisov et. al [10] found a shortcoming in key administration, with the outcome that after an assailant had gotten an adequate number of parcels, she could see all movement and infuse counterfeit
Cryptography is such a broad part of our lives we do not even notice the smallest applications, shopping on eBay or watching satellite television. I bet you even used cryptology when you were in school and did not even know it. Ever write a message in numbers instead of letters? Each letter of the alphabet correlated to its number position in the alphabet. The number sequence 3,16,25,12,20,15,12,15,7,25 equals cryptology. This is a form of cryptology in its most basic form. Webster's dictionary defines Cryptography as :
One of the largest parts of commerce is transaction. Transactions are needed anytime two parties exchange money or information. Since the Information Age has begun, transactions are more common over the Internet, where it is more imperative that transactions are secure (Klein x). Corporations have also become more widespread, which means that cryptography is needed to secu...
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.
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:
Nowadays, the information is the most treasured asset in an organization, due to it along with the experience represents the input necessary to take appropriate decisions and consequently to have success in the business. Almost all the information and knowledge related with the processes business, goods and services offered by a company, is processed, managed and stored through technology and information systems, thus the security of information has become increasingly important and plays a critical role in the enterprise government.
