Abstract:
A secure demand paging (SDP) system includes a dynamic random access memory (DRAM), a microprocessor having a secure internal memory and coupled to said DRAM, and a non-volatile memory storing a representation of operations accessible by the microprocessor. The stored representation of operations includes a coded physical representation of operations to configure an SDP space in the DRAM, to organize the SDP space into virtual machine contexts, to organize at least one of the virtual machine contexts into block book keeping blocks and book keeping spaces in the block book keeping blocks, and to execute a secure demand paging process between said secure internal memory and said DRAM.
