Abstract

In this paper, a Blowfish encryption algorithm for information secruity is designed and analyzed. The work is done for networking and communication application for enhanced network security and defence applications. In the proposed Blowfish algorthim reduce rounds of algorithm and proposed single blowfish round. The design simulation is done by Xilinx ISE software using the language of VHDL. Cryptography is the one of the main categories of computer security that converts information from its normal form into an unreadable form. its ability to secure the protected data against attacks and its speed and efficiency in doing so.
