Abstract
A data converter (1) capable of reducing a size of the total implementation in a device is a processing apparatus that performs secret converting processing predetermined to input data with 64 bits, the data converter including a finite field polynomial cubing unit (10), data integrating units (11a) to (11d), (12) and (13), a first converter (14), a second converter (15), a data splitting unit (16), and a data integrating unit (17). The finite field polynomial cubing unit (10) performs cubing, on the 32 bits data, in the polynomial residue class ring with a value in the finite field GF (28) as a coefficient and respectively outputs data with 32 bits.
