Range Extension for Weak PRFs; The Good, the Bad, and the Ugly

We investigate a general class of (black-box) constructions for range extension of weak pseudorandom functions: a construction based on m independent functions F1, . . . , Fm is given by a set of strings over {1, . . . , m}, where for example {〈2〉, 〈1, 2〉} corresponds to the function X 7→ [F2(X), F2(F1(X))]. All efficient constructions for range expansion of weak pseudorandom functions that we ...
