  After a brief introduction to a new chaotic stream cipher Mmohocc which
utilizes the fundamental chaos characteristics of mixing, unpredictability, and
sensitivity to initial conditions, we conducted the randomness statistical
tests against the keystreams generated by the cipher. Two batteries of most
stringent randomness tests, namely the NIST Suite and the Diehard Suite, were
performed. The results showed that the keystreams have successfully passed all
the statistical tests. We conclude that Mmohocc can generate high-quality
pseudorandom numbers from a statistical point of view.
