Zusammenfassung:This paper is focused on the synthesis and simulation of RC4 algorithm, which can be implemented on FPGA. A variable length key from 1 to 16 bytes is used by RC4 algorithm to initialize a 256-byte array. The subsequent pseudo-random bytes are generated by using this 256-byte array which is then generates a pseudorandom stream, which is EX-ORed with the plaintext/cipher text to give the cipher text/plaintext. The RC4 stream cipher has two phases which are key scheduling algorithm (KSA) phase and the pseudorandom generation algorithm (PRGA) phase. For every new key both phases must be performed. The RC4 is very successful algorithm in the field of cryptography because of its speed and simplicity and it is very easy to develop this algorithm in both software and hardware. The RC4 code is written in verilog language and based on synthesis result it can be further downloaded on FPGA for its hardware realization.
