Paper Title:Crypt Analysis Of DES Cryptosystem Over Man In The Middle Attack


In this paper, we are developing the DES (Data Encryption Standard) algorithm to minimize the possibility of getting attacked from the hacker to break the crypto code. Moreover, this will result in increase over security level to protect data over the network attacks. This design also shows the strength of encryption and decryption process with reference to the reasonable overhead. Here the paper objective is to show the tuned DES to the common mathematical attack especially man-in-the-middle attack.For the security issues in the internet, cryptography is one of the most important nowadays. Designing a cipher for data exchange between one node to other node deals with one of the troubleshooting job. In our algorithm we try to bring in a new system in the field of cryptography. We are hopeful that this new system will sure minimizes the overhead of data or key exchange between nodes.
