| Abstract(in English) | In this paper, a new class of Public-Key Cryptosystem (PKC) based on Random Simultaneous Equation of degree g(RSE(g)PKC) is presented. The proposed schemes are constructed on the basis of randomness. We present three classes of random quadratic transformation for the construction of a new class of RSE(g)PKC referred to as K(I)・RSE(g)PKC. We show that a sub-class of K(I)・RSE(g)PKC, K(I)・RSSE(g)PKC where random singular simultaneous equations of a large width t (number of variables) are used, can be secure against the various excellent attacks such as Grobner basis attack, Patarin's attack and Braeken-Wolf-Preneel attacks, due to the random transformations. |
