Abstract
Disclosed are apparatuses, systems, and techniques to perform and facilitate secure ladder computational operations whose iterative execution depends on secret values associated with input data. Disclosed embodiments use masking factors that re-blind secret data without exposing the unmasked secret data between iterations of the ladder computations. Some disclosed embodiments use Montgomery multiplication techniques to facilitate secret data masking by efficiently avoiding modular division operations. Disclosed embodiments significantly reduce the vulnerability of ladder computations to adversarial side-channel attacks.
