Cryptosystem using multivariable polynomials

Let us consider a message M an element (m1,m2, . . . ,mk) in a Galois field GF (2k), and multiply it by a product of polynomials beta 1(alpha)-alpha t(alpha) into M(alpha).<paragraph lvl="0"><in-line-formula>M(alpha)=Mbeta1(alpha).Mbeta2(alpha) . . . Mbetat(alpha)< / in-line-formula>Combine a noise vector r(alpha) of n-k to M(alpha) in series so that the data is expanded into degree n. Next, they are transformed into Γ by permutation. Γ is multiplied by an element gammax in the Galois field GF(2n) into cyphertext C(M), where gamma is a primitive root of the multiplicative group of the Galois field GF(2n). Practically, when the message M is substituted for X in a public key C(X), the cyphertext C(M) is obtained. The cyphertext C(M) is multiplied by gamma-x, is applied to an inverse permutation, and the noise vector r(alpha) is separated. Then, the inverse element of the product of beta1(alpha)-betat(alpha) is multiplied and is raised to an adequate index. Then the decrypted message is obtained.
