Motivated by a recently introduced HIMMO key predistribution scheme, we investigate the limits of various attacks on the polynomial interpolation problem with mixedmodular operations and hidden moduli. We firstly review the classical attack and consider itin a quantum-setting. Then, we introduce new techniques for finding out the secret moduli and consider quantum speed-ups.
