Abstract

See full text

The invention provides a processor device having an executable, white-box-masked implementation of a cryptographic algorithm implemented thereon. The white-box masking comprises an affine mapping A, which is so designed that every bit in the output values w of the affine mapping A depends on at least one bit of the obfuscation values y, thereby attaining that the output values w of the affine mapping A are statistically balanced.
