Abstract
Some embodiments are directed to an electronic cryptographic device arranged to perform a cryptographic operation on input data obtaining output data. The cryptographic device stores an internal state as sets of shares. Fourier coefficients corresponding to the sets of shares satisfy a predetermined relationship among them. The cryptographic operation is performed by repeatedly updating the internal state.
