Introduction: Physical one way functions (POWF) are functions that combine an input value with the state of a physical system to produce an output value. In addition, they have in common with classical one way functions (OWF) that they are difficult to invert: given an output value, it is hard to find an input value and a physical system that would produce that output. POWFs were introduced in [1], where they are implemented by shining a mobile laser beam through a nonhomogenous
