Modification of Des Algorithm

This research paper discusses the modification of DES algorithm, which is the science of data encryption, a technology that provides for a safe, secure, and private information exchange.PN Generator produce the infinite random numbers which can be used to modify the DES algorithm to make it more critical to decipher. The modified encryption of data cannot be deciphered by DES algorithm. It enables you to send the secure data between two computers on private wireless link.
