I don't think simulating a physical source is itself a big challenge.  People simulate complicated probabilistic behavior all the time.  The challenge is going to be sticking it into the chip in a way that doesn't show up when the chip is taken apart in a lab.

How can we design the whole system so that some compromised or flawed pieces don't wreck us?  I don't know how to ensure my chip's hardware RNG isn't hacked, but I have some hope of working out a design that will be robust even if it is hacked.
