Abstract
Solutions described herein refer to cryptographic data processing, utilizing a first masking scheme of a shared secret and a second masking scheme of the shared secret, wherein a transformation from the first masking scheme to the second masking scheme is conducted by forcing one type of calculation among at least two types of calculations.
Claims14
A method for cryptographic data processing, the method comprising:
- utilizing a first masking scheme of a shared secret and a second masking scheme of the shared secret,
