| Abstract(in English) | The dependency to random oracle is not same in all cryptographic schemes which are secure in the random oracle model (ROM) because all properties which a random oracle has (collision-resistance, hash value is truly random, etc) are not necessary for all cryptographic schemes. In this paper, we introduce a variant of the ROM where inspection of hash list is allowed. In this setting, the adversary can access the hash list of the random oracle at any time. Moreover, we consider the dependency of cryptographic schemes (OAEP, Fujisaki-Okamoto Transformation, FDH) utilizing this model. |
