There are provided a method for elliptic curve cryptography with countermeasures against simple power analysis and fault injection analysis, and a system thereof. According to an aspect, there is provided a method for elliptic curve cryptography, in which an elliptic curve point operation is performed to generate an elliptic curve code, including: receiving a first point and a second point on the elliptic curve, wherein the first point is P0=(x0, y0) and the second point is P1=(x1, y1); and performing doubling if the first point is the same as the second point, and performing addition if the first point is different from the second point, to thereby obtain a third point, wherein the third point is P2=P0+P1=(x2, y2). Accordingly, it is possible to provide countermeasures against a side channel analysis attack. |
