Apparatuses, systems, and techniques to perform a cryptographic operation using multiple iterations, wherein each iteration includes two or more stages operating in parallel on inputs derived from a common value, one of the stages computing real data and other stages computing dummy data.

Comprehensively obfuscated cryptographic accelerators and operations thereof

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 balance execution of various iterations in a way that is balanced for different secret values, significantly reducing vulnerability of ladder computations to adversarial side-channel attacks.

Techniques, devices, and instruction set architecture for balanced and secure ladder computations

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.
