Design Of High Performance Rc4 Stream Cipher For Secured Communication

R.Prabu

The main feature of cryptography is to work out with problems, which are associated with secrecy, authentication and integrity. Cryptography also, is related with the meaning of protocol. A protocol is sequences of actions, which are concern two or more sides, designed to fulfill a goal. Thus, a cryptographic protocol is a protocol that uses cryptography. This protocol uses a cryptographic algorithm and its intention is to prevent attempts of thefts and invasions.RC4 is the most popular stream cipher in the domain of cryptology, In this project we propose the fastest known architecture for the cipher with the help of loop unrolling and hardware pipeline which is produce the one RC4 key stream byte per clock cycle. We have optimized and implemented our proposed design using VHDL description Synthesized with 65nm fabrication technology at clock frequency of 1.37 GHz to be obtained a final key stream throughput 30.72Gbps.
