RC4, often referred to as Alleged RC4 (ARC4) in open literature, was and probably still is the most popular stream cipher. Although some weaknesses in its key scheduling algorithm have been reported and new faster and claimed secure stream ciphers have been proposed, ARC4 is likely to remain as a big player in cryptographic applications. In this paper, we propose a new variant of ARC4, called Modified ARC4 (MARC), which enhances the security of ARC4 by modifying its key scheduling algorithm and improves the performance by modifying its pseudo-random generation algorithm. MARC retains the simplicity of ARC4 and is faster than most software-efficient finalists of eStream.
