In practical cryptography, a PUF or Physical Un-clonable Function is a function that is embodied in a physical structure, that is easy to evaluate but hard to characterize (see http://en.wikipedia.org/wiki/Physically_Unclonable_Function)
Check out Raviknath Pappu's thesis on the construction and application of physical one-way functions for secure communications @ http://pubs.media.mit.edu/pubs/papers/01.03.pappuphd.powf.pdf
