Shigeo Tsujii, Kohtaro Tadaki, Ryou Fujita, Masahito Gotaishi, and Toshinobu Kaneko

Abstract

Following the last proposal of the nonlinear Piece in Hand method, which has 3-layer structure, 2-layer nonlinear Piece in Hand method is proposed. Both of them aim at enhancing the security of existing and future multivariate public key cryptosystems. The new nonlinear Piece in Hand is compared with the 3-layer method and PMI+, which was proposed by Ding, et al.
