WebApr 27, 2024 · A cryptographic hash function h: { 0, 1 } ∗ → { 0, 1 } n is said to be weakly uniform if for every hash value there are infinitely many collisions, i.e. h − 1 ( { h ( x) }) is infinite for every x ∈ { 0, 1 } ∗. (The pidgeonhole principle only implies the existence of one x ∈ { 0, 1 } ∗ such that h − 1 ( { h ( x) }) is infinite.)
