Implemention in C of the higher-order masking scheme proposed in [0] with CPRR method from [1].

The AES implementation uses the Common Shares method [3], and the Random Reduction method [2] to increase the performance of the implementation.

The most interesting function is the 'SecEvalCombined' function which implements the Common Shares and Random Reduction from [2] and [3] respectively.
