Abstract (in Japanese) (See Japanese page) 
(in English) One of the anthers, Kasahara, have been proposed several public key cryptosystems based on multivariate polynomials with suede random simultaneous equations which are systematically constructed. Recently, the another anther, Sakai, shows that these suede random simultaneous equations can be easily solved by Gr"obner basis attacks. These constructions and attacks have been expected to progress of the research of multivariate public key cryptosystem in the future.
In this paper, we show Kasahara's novel construction of the suede random simultaneous equations and Sakai's noteworthy attack on this PKC.
