In spite of several crypto analytical criticisms on RC4 data encryption algorithm, its simplicity, speed has made it one of the popular encryption techniques employ in wireless communication networks. However, in recent time many experts no longer consider RC4 secure against attacks. This is due to some vulnerability detected through repetition of keys over a period of time. This exposes the weakness of the exclusive OR operator on which the RC4 technique is anchored. In recent time, another variant of RC4 was developed called RC42s.
