Abstract:
Methods and systems for masking certain cryptographic operations in a manner designed to defeat side-channel attacks are disclosed herein. Squaring operations can be masked to make squaring operations indistinguishable or less distinguishable from multiplication operations. In general, squaring operations are converted into multiplication operations by masking them asymmetrically. Additional methods and systems are disclosed for defeating DPA, cross-correlation, and high-order DPA attacks against modular exponentiation.

Claim (Index 7):
The system of  claim 1 , the code being further configured to apply at least one dummy multiplication operation during calculation of the intermediate values.
