ABSTRACT:
A sub converter330provided in a data conversion apparatus for data encryption/decryption includes a data conversion function and a data transfer function or key transfer function, the sub converter converts data and transfers data that is nonlinear converted in a main converter320or a key that is outputted from a key KL register240,by switching between the data conversion function and the data or key transfer function.
