Statistical weaknesses in 20 RC4-like algorithms and (probably) the simplest algorithm free from these weaknesses - VMPC-R
Abstract: We find statistical weaknesses in 20 RC4-like algorithms including the original RC4, RC4A, PC-RC4 and others.
This is achieved using a simple statistical test.
We found only one algorithm which was able to pass the test - VMPC-R.
This algorithm, being approximately three times more complex then RC4,
is probably the simplest RC4-like cipher capable of producing pseudo-random output.
