Abstract

In the modern era of computation security is the most essential matter. Nowadays everyone is concerned about data abstraction. In this paper, a simple yet standard cryptography algorithm has been introduced which can easily be implemented and used by common people. Here, as an introductory approach a text file with some data has been taken and encrypted using a new symmetric key cryptography algorithm and the decryption has been done using the same where each 32 bit from the plain text has been selected and expanded using an Expansion Function and a 64 bit key has been processed and used for the encryption of the expanded plain text. That encrypted text is then shrunk back to 32 bit cipher text. The decryption is done in the same procedure.

Key-Words / Index Term
