SPA Attack for A Kind of Operation to Balance Point Addition and Doubling on Scalar Multiplication in Elliptic Curve
Huang Shi-zen · Journal of Chengdu University of Information Technology · 2013
This paper analysis a kind of methods to resist side channel attacks using the operation to balance point addition and doubling on scalar multiplication in elliptic curve.Although this operation makes no distinguish information of point addition and doubling,we can still get scalar information when it is shown in binary.Traditional power attack mainly concentrated in the distinguish between point addition and doubling,but this paper transferred attention to the differences by power consumption between statement and,and through SPA attack,successfully get the Key information from the power curve of scalar multiplication in elliptic curve after point addition and doubling.
