  • KEY UPDATE FOR MASKED KEYS
    Publication number: 20200076594
    Abstract: Embodiments of the present invention provide methods to perform key updates on key shares of a masked key, which allows updating the masked key without unmasking the masked key (e.g., producing the effective key). By using key shares of a masked key and performing the key update on one or more of the key shares without unmasking the effective key, the cumulative leakage of individual effective keys across multiple cryptographic operations is reduced, and preferably minimized.

  • MINIMIZING INFORMATION LEAKAGE DURING MODULAR EXPONENTIATION AND ELLIPTIC CURVE POINT MULTIPLICATION
    Publication number: 20190238310
    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.
