  • Encipher A Symmetric Key
    335 words
    Cryptography Cryptography is way you can keep information secure. A person who does not know the method used to change the information to keep it secure cannot copy the method used or reverse the change. The basic components of cryptographic systems are used to encipher (scramble) information so that it is difficult to determine the meaning without the appropriate key or key (s) to decipher (unscramble) the information. The components include cryptographic algorithms (mathematical functions) for...
  • Company's Authenticated Public Key
    3,908 words
    1 Introduction The recent acceleration in the uptake of electronic commerce (e-commerce) over the Internet has focused the need for methods to be developed by which to securely transfer data over what amounts to a worldwide public network.

  • Public Key Algorithm In 1977
    2,721 words
    INTRODUCTION One important, yet practical, application of complexity theory is cryptography. It has become one of the main tools for privacy, trust, electronic payments, and other forms of security. It is no longer just a military tool and the advantages it provides should be used to the fullest extent. This paper will discuss basic terminology and main methods of cryptography. BASIC TERMINOLOGY Cryptography is the science of scrambling text so that no one can read it except for the intended rec...
  • Same Secret Key To Decrypt The Message
    910 words
    Traditional cryptography is based on the sender and receiver of a message knowing and using the same secret key: the sender uses the secret key to encrypt the message, and the receiver uses the same secret key to decrypt the message. This method is known as secret-key cryptography. The main problem is getting the sender and receiver to agree on the secret key without anyone else finding out. If they are in separate physical locations, they must trust a courier, or a phone system, or some other t...
  • Public Key Encryption Algorithm
    2,691 words
    System Security System security is the amount of protection against unforeseen events, which might cause the system to fail. The amount of security in a given system depends upon the value of the information contained within the system. As the information becomes more valuable, the amount of money spent on protecting the information also increases. An example of this would be someone keeping their valuables in a home fire safe whereas a bank might keep their valuables in a time-controlled vault....
