Ah, OK. Unfortunately there's no source code, and no test vectors. So I'm a bit wary of "rolling my own". That being said, Page 5 has this text: It is straightforward to distinguish between a real random bitstream and a one produced by ISAAC initialised with a state with constant value, since the latter shall have about half of the ωi equal to 2X. The full state can even be trivially recovered in a few seconds with a paper and a pen Which definitely sounds bad. :( I'll take a look at doing some tests with source code.
