| Abstract(in English) | Iwata has shown the method for building a pseudorandom function from a random permutation. Unlike previous building methods, his method provides the pseudorandom function such that the output size is larger than that of the underlying random permutation. If his method is secure, then his method is applicable to construct the efficient counter mode. In this paper we discuss the security of his method by using the security analysis of a previous building method. We show that it is not easy to improve the security of pseudorandom functions built by similar methods substantially. |
