More Information
Summary:The calculation, by an electronic circuit, of a result of an integral number of applications of an internal composition law on elements of an abelian group, by successive iterations of different steps according to the even or odd character of a current coefficient of a polynomial representation of said integer, the degree of which determines the number of iterations, each iteration including whatever the even or odd character of the current coefficient, updating of at least one variable conditioning the final calculation result.
