Abstract
A first arithmetic input share and a second arithmetic input share of an initial arithmetically-masked cryptographic value are received. A sequence of operations using the arithmetic input shares and a randomly generated number is performed, where a current operation in the sequence of operations generates a corresponding intermediate value that is used in a subsequent operation. At the end of the sequence of operations, a first Boolean output share and a second Boolean output share are generated. The arithmetic-to-Boolean mask conversion is independent of the input bit length.
