Abstract
According to an aspect of the present invention, there is provided a non-linear data converter including: first to fourth converters that each performs a respective converting process on an input bit string to output respective output bit string; a generator that generates a random number bit string; and a selector that selects any one of the output bit strings from the first to fourth converters based on the random number bit string. Each of the converting processes is equivalent to performing a first mask process, a non-linear conversion predetermined for an encoding or a decoding and a second mask process.
