We formalize the notion of several weakened random oracle models in order to capture which property of a hash function is crucial to prove the security of a cryptographic scheme. In particular, we focus on augmenting the random oracle with additional oracles that respectively return collisions, secondpreimages, and first-preimages. We study the security of the full domain hash signature scheme, as well as three variants thereof in the weakened random oracle models, leading to a separation result. |
