Abstract
A method of securing a virtual address space against unauthorized access from an unauthorized agent includes generating a superimposed address space corresponding to the virtual address space, dilating the superimposed address space by inserting dummy memory at a plurality of locations in the superimposed address space, and displacing the superimposed address space by shifting a segment of the superimposed address space by a d-bit key. A computer processor includes a memory and a dedicated functional unit in a stage of a pipeline of the computer processor, the computer processor including an instruction that when executed by the dedicated functional unit causes the computer processor to translate one or more pointers between displaced and dilated address spaces of the memory and virtual address spaces of the memory.
