Abstract. We propose a general transformation that maps a cryptographic protocol that is secure in an extremely weak sense (essentially in a model where no adversary is present) in...
Every public-key encryption scheme has to incorporate a certain amount of randomness into its ciphertexts to provide semantic security against chosen ciphertext attacks (IND-CCA). ...
