Abstract
A secure computing device, including: a processor configured to carry out a secure operation; a memory in communication with the processer configured to store secure data; and a memory controller configured control storage of data in the memory and reading data from the memory, wherein the secure data is split into shares before being stored in the memory and wherein the memory controller is configured to: apply a masking storage transform (MST) to one of the shares to produce a masked share before storing the shares in the memory, wherein the MST is a permutation without a fixed point; apply an inverse MST to the masked share when reading the shares from the memory; and combine the read shares to reconstruct the secure data.
