| Abstract(in English) | We introduce a new definition of semantic security. The new definition is valid against not only chosen-plaintext attack but also chosen-ciphertext attack whereas the original one seems to be defined against only chosen-plaintext attack. We show that semantic security formalized by the new definition is equivalent to indistinguishability, due to Goldwasser and Micali for public-key encryption schemes. Relations between semantic security by the new definition and semantic security by Goldwasser and Micali are discussed. Semantic security by the new definition implies semantic security defined by Goldwasser and Micali, but the implication of the opposite direction does not hold. |
