Minimizing information leakage during modular exponentiation and elliptic curve point multiplication

摘要

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.
