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 use a new class of trap-doors based on two classes of transformation, i.e. random transformation and message-dependent random transformation. For constructing the proposed scheme, two random transformations φ and χ are used. The transformation φ would yield a breakthrough to a field of multivaliate cryptosystem in a sense that φ is dependent on a message. Namely it is a time variant transformation on the basis of random coding. We show that the proposed PKC's, 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 using new trap-doors. |
