– RC4 Stream Cipher, a kind of symmetric cryptography is one of the most famous stream ciphers in the field of Encryption Technologies. It was designed by Ron Rivets in the year 1987 is the most widely positioned commercial stream cipher. Its applications is mostly prominent in the area of network communication where widely used network protocols such as WPA, WEP, SSL and in Secure SQL, Microsoft Windows, Apple OCE, etc. are active. In this project, we have focused on the synthesis and simulation of RC4 algorithm using Verilog and the results can be further compared with the other ciphers. This project compacts with RC4 key stream generator, within the possibility of the model of an exchange shuffle, in order to attain improved safety. The main factors in RC4's realization over such a widespread range of solicitations are its speed and ease of implementation. The RC4 program is written in Verilog language and based on synthesis result it can be further downloaded on FPGA for its hardware realization (if needed).
