Eurocrypt'98에서 Okamoto와 Uchiyama는 인수분해를 기반으로 한 새로운 트랩 도어(단방향) 기능을 선보인 반면, Fujisaki와 Okamoto는 CRYPTO'99에서 단방향 암호화에서 선택 암호 보안 암호화로의 일반적인 전환을 보여주었습니다. 무작위 오라클 모델에서. 본 논문에서는 두 가지 방식을 결합한 결과가 (임의의 조합이 아닌) 잘 조화를 이루고 정확한 보안 측면에서 [6]에서 기대하는 것보다 보안 수준이 향상됨을 보여줍니다. - 방식의 보안 조합에 의해 산출된 값은 인수분해에서 엄격하게 감소됩니다. 또한 이 문서에서는 새로운 방식에 대해 자세히 설명합니다. 이러한 유형의 암호화는 제대로 구현되지 않으면 심각한 피해를 입을 수 있기 때문입니다. 제안된 방식은 적어도 [2],[4],[13]과 같은 다른 선택 암호 보안 비대칭 암호화 방식만큼 효율적입니다.

Abstract: At Eurocrypt'98, Okamoto and Uchiyama presented a new trap-door (one-way) function based on factoring, while Fujisaki and Okamoto, at CRYPTO'99, showed a generic conversion from just one-way encryption to chosen-cipher secure encryption in the random oracle model. This paper shows that the result of combining both schemes is well harmonized (rather than an arbitrary combination) and, in the sense of exact security, boosts the level of security more than would be expected from [6]--The security of the scheme yielded by the combination is tightly reduced from factoring. This paper also gives a rigorous description of the new scheme, because this type of encryption may suffer serious damage if poorly implemented. The proposed scheme is at least as efficient as any other chosen-cipher secure asymmetric encryption scheme such as [2],[4],[13].
