Abstract:
We introduce a new primitive, called trapdoor hash functions (TDH), which are hash functions H : {0, 1}(n) -> {0, 1}(lambda) with additional trapdoor function-like properties. Specifically, given an index i is an element of [n], TDHs allow for sampling an encoding key ek (that hides i) along with a corresponding trapdoor. Furthermore, giv...More
