The masking method is known to be one of the most powerful algorithmic countermeasures against the first-order differential power attack. This article proposes several new efficient masking algorithms applicable to finite field multipliers. Note that the finite field multiplier (more precisely, the finite field inversion) plays a crucial role in the confusion layer of many block ciphers including AES. The new algorithms are applied to implement AES DPA-securely in hardware and the detailed implementation results are presented.
