Abstract:
A time-invariant method and apparatus for performing modular reduction that is protected against cache-based and branch-based attacks is provided. The modular reduction technique adds no performance penalty and is side-channel resistant. The side-channel resistance is provided through the use of lazy evaluation of carry bits, elimination of data-dependent branches and use of even cache accesses for all memory references.
