ARITHMETIC CIRCUIT FOR OBTAINING THE VECTOR PRODUCT OF TWO VECTORS

In an arithmetic circuit, a first input of m bits representing the vector expression of a first set of elements of a finite field GF(2m) is converted into the components of a matrix, and each component of the matrix is multiplied by second input of m bits representing the vector expression of a second set of elements of the finite field. A vector product of the first and second inputs is thereby obtained.
