Abstract

In this research we have proposed a new self-developed symmetric algorithm called FJ RC-4, which is derived from RC4. Our studies shown that KSA is the vulnerable stage of RC4, whereas a new self-developed symmetric algorithm, FJ-RC4, is an attempt to increase the security of RC4 by introducing the new algorithm for the KSA stage. We have investigated and compared the robustness of the RC4 and FJ-RC4 and shown that FJ-RC4 is stronger than RC4 against the attacks. In addition, it takes more time to find key in FJ-RC4 and requires more resources. Thus, it would lead us to a more secure algorithm in addition to the fact that FJ-RC4 keeps RC4 simplicity in the core algorithm, PRGA. In addition this idea can be more efficient if KSA and PRGA stages are conducted concurrently.
