Provable hash

WebbIn regard to provable designs, although section B.1 does mention the possibility of a security reduction proof, the bulk of the document seems to suggest that the goal of the hash function is to achieve multiple properties including random oracle behavior. Historically, provable hash properties and random oracle behavior have been disjoint … Webb12 apr. 2024 · A hash function is another method involved in data encryption.
