Title: Device for finding solution of simultaneous equations of finite field and inverse element computing device
Inventor: FUDA YUICHI
IPC: G09C5/00
Filed: 2000-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a device for finding the solution of simultaneous equations on a finite field which can reduce the computational quantity of a method for finding the solution of the simultaneous equations on the finite field. SOLUTION: An equation transforming section 102 generates the matrix M' of an equation M'x=v' having an equivalent relation with simultaneous linear equations Mx=v with (n) variables and a vector v' by triangulating a matrix M and a vector (v), with the matrix M being transformed into an upper triangular matrix so as to prevent each diagonal component of the matrix M from being transformed into '1'. An inverse element computing section 103 computes the inverse elements of the diagonal components of the matrix M' and an equation computing section 104 calculates the solution of the equation M'x=v' by using the inverse elements of diagonal elements, M' and v'. An inverse element transforming section 203 computes the inverse element I of the element of the expanded field GF(q) of a finite field GF(p) based on the solution.
