Abstract

A secure demand paging system includes a secure internal memory having a table relating physical addresses to virtual addresses, a non-volatile memory, a decryption module and a hash module between the secure memory and the non-volatile memory to allow for decryption and integrity verification of data stored in the non-volatile memory during a transfer to said secure memory and means for connecting the secure memory to a volatile page swap memory such that the non-volatile memory is bypassable during a page swap.
