WebJan 13, 2024 · For some cryptographic primitives, such as one-way permutations and homomorphic encryption, we know that the answer is yes ---they imply hard problems in N P ∩ c o N P and S Z K, respectively. In contrast, one-way functions do not imply such hard problems, at least not by black-box reductions.
