Cryptography has a powerful tool used with computers and the computer network security. This paper will explore the threats, the can and cannot do the threats, system design, implementation, state of security, etc. All systems using cryptography for authentication and privacy with the strongest cryptographic can still be vulnerable with upstream and downstream threats. The secure session of the authentication will require the secure user to have authentication and secure computer authentication.

After reading Why Cryptography Is Harder than It Looks, Bruce Schneir explained it very well making it easy to understand why you need to use it.

Cryptography is the essential for the information systems, helping to provide accountability, accuracy, confidentiality, and fairness. Cryptography is designed to prevent fraudulent activity with the electronic commerce insuring the validity of all financial transactions. Also proving that is can help to protect the identity/anonymity while keeping the vandals from making changes to the Web page and prevent all industrial competitors from getting into the confidential documents the company has.

“As the Net and the Web move into more central positions in the life of the world, the functions that cryptography provides (including secrecy, integrity, and digital signatures) become more important, and cryptographic functions can be found in more places, doing more things.” (Morar, Chess, & Watson)

As the commerce and communication continue to move, forward with computer networks the use of cryptography will become more vital. “The cryptography now on the market does not provide the level of security it advertises. Most systems are not designed and implemented in concert with cryptographers, b...

The cryptography is designed with consideration of the users' needs, and integrated, so it can protect the systems, resources, and data. The hard part about cryptography is getting people to use and understand it; users do not know how to compare secure systems.

    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.

    Cryptography or Cryptology comes from the Greek words kryptós meaning "hidden, secret” and graphein, "writing", So cryptography is the study/practice of hidden writing, or coding messages in order to send messages between two parties without a third party being able to read the messages. Cryptography is a process invented thousands of years ago, but was tedious to use as messaged had to be drafted, encoded, transported, decoded before reaching its intend recipient. It wasn’t until the early 20th century when mechanical devices cable of complex mathematical calculations were designed to automate the encoding and decoding of messages in such complex ways that it would be near impossible to decode by hand. An example of this

    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 Definition and Importance of Data Encryption

    2007 Words  | 5 Pages

    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.

    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.

    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:
