    摘要: According to each embodiment of this invention, an encryption apparatus, decryption apparatus, and key generation apparatus based on a public-key cryptographic scheme whose security is based on the divisor finding problem of obtaining a divisor on an algebraic surface which is a difficult problem that has not been solved by contemporary mathematics are realized by an arrangement using, as a private key, a section D of algebraic curves (divisors) on a fibration X(x, y, t) of an algebraic surface X. This makes it possible to create a public-key cryptographic scheme which can ensure security even in the advent of a quantum computer, can be securely realized by even current computers, and can be realized in a low-power environment.

    摘要: The present invention aims to provide a fuel cell anode, a membrane electrode assembly and a fuel cell, so as to obtain high electric power. The fuel cell anode has an electrode catalyst layer, and the electrode catalyst layer comprises a supported catalyst comprises electrically conductive carriers and fine catalytic particles supported thereon, a proton-conductive inorganic oxide supporting SiO2 on its surface, and a proton-conductive organic polymer binder. The SiO2 supported on the inorganic oxide prevents the oxide particles from growing, to ensure the high electric power. It is necessary to control the mixing ratios among the supported catalyst, the proton-conductive oxide and the proton-conductive binder in particular ranges.

    摘要: An encryption apparatus generates two random three-variable polynomials r(x,y,t) and s(x,y,t) to be constituted of like terms of a variable xiyj (where i and j are degrees that are zero or more) when two multiplication results X(x,y,t)r(x,y,t) and f(t)s(x,y,t) are regarded as polynomials of x and y, and generates an encrypted text F from a plaintext polynomial m(t) by using the two multiplication results X(x,y,t)r(x,y,t) and f(t)s(x,y,t).
