Essay on Cryptography; Essay on Cryptography. 2196 Words 9 Pages. Cryptography Part one---Why do we need to learn cryptography Now is a time which the information is extremely development. A lot of datas are stored by the form of electronic messages. The transmission of the information is often through electronic medium such as mobile phone communication, electronic commerce, the on-line chat.
According to the history of cryptography, Diffie Hellman and Merkle Have become famous as cryptographers who explored the concept of public-key cryptography, while Rivest, Shamir and Adleman developing the new kind of public key cryptography as RSA, the most beautiful implementation of this cryptosystem. Public key cryptography was originally.
There are three main types of cryptographic algorithms: (1) secret key, (2) public key, and (3) hash functions. Pick an algorithm for any one of these types (e.g., DES, AES, RSA, MD5) and describe how it works and where it is applied (For example SSL uses 3DES or DES) for message encryption.
Since RSA and cryptography involve university-level mathematics such abstract algebra and number theory, I think the best way to introduce RSA to secondary students is to discuss the generality of public key versus private key cryptography and provide many interesting application problems in order to encourage students to study this field.
Why Cryptography Is Harder Than It Looks. Bruce Schneier; Information Security Bulletin; 1997; From e-mail to cellular communications, from secure Web access to digital cash, cryptography is an essential part of today's information systems. Cryptography helps provide accountability, fairness, accuracy, and confidentiality. It can prevent fraud.

Cryptography is a tool which may alleviate many of the perceived problems of using the Internet for communications. However, cryptography requires the safe implementation of complex mathematical equations and protocols, and there are always worries about bad implementations. A further worry is that users are integral to securing communications.
RSA is an example of public-key cryptography, which is illustrated by the following example: Suppose Alice wishes to send Bob a valuable diamond, but the jewel will be stolen if sent unsecured.Both Alice and Bob have a variety of padlocks, but they don't own the same ones, meaning that their keys cannot open the other's locks.
The Mathematics of the RSA Public-Key Cryptosystem Burt Kaliski RSA Laboratories ABOUT THE AUTHOR: Dr Burt Kaliski is a computer scientist whose involvement with the security industry has been through the company that Ronald Rivest, Adi Shamir and Leonard Adleman started in 1982 to commercialize the RSA encryption algorithm that they had.
RSA Cryptographic Algorithm Introduction Cryptography algorithms broadly refer to the techniques that are used for securing communication in the presence of adversaries. It mainly involves the construction and analysis of protocols that are aimed at overwhelming the effects of the third parties in a communication environment with the principal objective of ensuring data integrity.
Cryptography is mainly determined with the success of Cryptanalysis and thus Factorization methods, are also presented in this part. In the third part of the essay, after the explanation of Multi-Prime RSA and calculation of optimum value for the Multi-Prime RSA, Standard RSA and Multi-Prime RSA are compared.
The public-key system can be used to encrypt a secret key which is then used to encrypt the bulk of a file or message. This is explained in more detail in How is RSA used for encryption in practice? In the case of RSA, Public-key cryptography is not meant to replace secret-key cryptography, but rather to supplement it, to make it more secure.
