Title: Writing program in C++ or Java to implement RSA algorithm for key generation and cipher verification. Objective: To study‚ 1. Public key algorithm. 2. RSA algorithm 3. Concept of Public key and Private Key. Theory: Public Key Algorithm: Asymmetric algorithms rely on one key for encryption and a different but related key for decryption. These algorithms have the following important characteristics: • It is computationally

U-571: Historically Accurate? U-571 was a movie released in April 2000 and directed by Johnathan Mostow. This movie depicted the capture of the Enigma cipher machine and other cryptographic documentation from a German U-boat by American forces disguised as Germans during spring 1942. According to the film makers‚ this film promised to be thrilling and exciting. Although the movie did live up to its promise‚ it fell short in the historical accuracy department. This film was split in terms of

scheme is a block cipher in which the plain text and cipher text are integers between 0 and n-1 for some n. * A Typical size of n is 1024 bits or 309 decimal digits. * This is a public key encryption scheme. * In this scheme two pairs of integers {e‚ n} and {d‚ n} are used. First of them i.e. {e.n} is called the RSA public key and the other one i.e. {d‚ n} is called the RSA secret key. * The sender uses the public key and encrypts the message say M into cipher text as – C =

Thomas Jefferson included the making of codes and ciphers among his many interests‚ putting his efforts to use in both private correspondence and public business. One of his inventions‚ the cipher wheel‚ has been described as being in "the front rank" of cryptologic inventions. The American Civil War created a new urgency for techniques in both cryptography (the manufacture of codes and ciphers) and cryptanalysis (the breaking of codes and ciphers). It also introduced new

The Zodiac murdered five known victims in Benicia‚ Vallejo‚ Lake Berryessa‚ and San Francisco between December 1968 and October 1969. Four men and three women between the ages of 16 and 29 were targeted. Others have also been suspected to be Zodiac victims‚ but they have been ruled inconclusive. The lack of consensus about the number of victims‚ the inability of law enforcement to crack the ciphers‚ and the fact that several

SMS encryption using Diife-Hellman May 4‚ 2012 Introduction 1.1 Background Nowadays mobile phone communications (phone calls) are used mostly by everyone due to the GSM technology. In mobile phones there are several services a person can use to communicate other than making a phone call such as; SMS‚ MMS‚ contact registry and cameras. The most commonly used service after phone calls is the SMS that most of us find it easier even faster to share or to communicate with one another. An SMS

| | IntroductionThe term “computer network’’ means a collection of autonomous computers interconnected by a single technology. Two computers are said to be interconnected if they are able to exchange information. The connection need not be via a copper wire; fiber optics‚ microwaves‚ infrared‚ and communication satellites can also be used. Networks come in many sizes‚ shapes and forms.
