Abstract:
Minimizing information leakage during modular exponentiation using random masks is disclosed Minimizing information leakage during elliptic curve point multiplication is disclosed with windowing by using point randomization is disclosed. Elliptic curve point multiplication with windowing calculates and stores multiple points based on the point being multiplied and then processes multiple bits of the multiplier at a time is also disclosed.

Claim (Index 4):
A method for minimizing information leakage during elliptic curve point multiplication, the method comprising:\n combining elliptic curve multiplier order randomization and multiplier splitting, generating at least two random numbers of any bit width (r1 and r2) and used for making; storing a first random multiplier (d1) as d+n*r1\u2212r2; storing a first intermediate result point (Y1) as a resulting point from an elliptic curve point multiply with multiplier (d1) and point X; storing a second intermediate result point (Y2) as a resulting point from an elliptic curve point multiply with multiplier (r2) and point X; and storing a resulting point Y as the point addition of Y1 and Y2 where Y=Y1+Y2=dX.
