Abstract
The present invention describes a method which improves the safety aspects of the previously published atomic blocks. This method builds new sets of atomic blocks designed to protect against both simple side-channel attacks and C-safe fault attacks for scalar multiplication for elliptic curves over prime fields. These atomic blocks are structured with the sequence of field operations (S, N, A, A, M, A), Squaring, Negation, Addition, Addition, Multiplication, Addition. These atomic blocks are applied to various operations in Jacobian coordinates: doubling, tripling, and quintupling, as well as mixed Jacobian-affine addition for use in left-to-right scalar multiplication.
