Power Analysis Attack On Elliptic Curve'S Point Multiplication
Information is becoming a crucial if not the most important resource of the economy and the society at large. Information can be copied without cost, it can be communicated at the speed of light and it can be destroyed without leaving traces. This poses new challenges for the protection of this new resource. Power Analysis Attack is a type of Side channel attack where information is gained based on power consumption. Power analysis Attack is examined for Elliptic Curve Cryptography implementation. Point multiplication is analyzed and Montgomery algorithm serves to be the best countermeasure.
