{"publication_status":"published","abstract":[{"text":"We investigate the security of &quot;padding-based&quot; encryption schemes in the standard model. This class contains all public-key encryption schemes where the encryption algorithm first applies some invertible public transformation to the message (the &quot;padding&quot;), followed by a trapdoor permutation. In particular, this class contains OAEP and its variants. Our main result is a black-box impossibility result showing that one cannot prove any such padding-based scheme chosen-ciphertext secure even assuming the existence of ideal trapdoor permutations. The latter is a strong ideal abstraction of trapdoor permutations which inherits all security properties of uniform random permutations.
