Abstract(in English) | In 2003, Tsujii et al. proposed multivariate type public key cryptosystem, named Piece In Hand Concept. This cryptosystem is an enhanced multivariate type public key by MOCHIGOMA matrix (PH matrix). They claim that it is difficult to derive the secret key. Because the Piece In Hand Concept is not included all the secret key in the public key. In this paper, we describe the technique of deriving equivalent PH matrix and report the security of Piece In Hand Concept. |
