Abstract
A key generating apparatus generates a fibration X(x, y, t)=0 of an algebraic surface X serving as a part of a public key and defined on a finite field F(where q=p[p is a prime number and r is an extended degree]) and a private key which is two sections Dand Dcorresponding to the fibration X(x, y, t)=0. The fibration X(x, y, t) is generated such that a term (c(t)xy) of xyhaving a 1-variable polynomial c(t) of t as a coefficient is included in the fibration X(x, y, t).
