Abstract: Aspects of the present disclosure calculate masked data shares dynamically inside the CPU boundary, and use a plurality of memory channels to write the masked data shares to an external memory location and/or to read the data shares from that external memory location. Each dynamically generated mask value is uniquely associated with a corresponding memory channel during writing data to the external memory. The modified masked data is unmasked or remasked during a subsequent read operation.
