Abstract (in Japanese) (See Japanese page) 
(in English) Although we have many computational reductions among the cryptographic primitives, little is known about the relationship between the integer factoring problem and the discrete logarithm problem, except that the former does not reduce to the latter under some condition. In other words, those two problems could be computationally separated. In this paper, we show that a straight-line program (SLP, for short) separates the strong $\mathsf{RSA}$ assumption from the $\mathsf{DDH}$ assumption.
