Abstract

The Data Encryption Standard (DES) was developed by an IBM team in the year around 1974 and it was adopted as a national standard in the year 1977.From that time, many cryptanalysts have tried in order to find different shortcuts for the breaking of the system. In this paper, the examination of one such attempt, the method of differential cryptanalysis, which were published by Biham and Shamir. There are some of the safeguards against differential cryptanalysis that were built into the system from the beginning, with the result that more than 1015 bytes of the chosen plaintext are required for this attack to succeed. Cryptography plays very important role in security of data. Cryptography means to transfer sensitive information across insecure networks like internet so that it cannot be read by anyone except the person whom we want to send it. It basically hides the information. The federal organization used the Data Encryption Standard (DES) which may be used to protect sensitive data. Cryptography algorithms are divided into Symmetric and Asymmetric key cryptography. Symmetric Cryptography is further divided into Block ciphers and Stream Ciphers.
