FIELD: computer engineering.
SUBSTANCE: invention relates to computer engineering. System for establishing physical locality between secure execution environments includes a first processor, including a first memory cell to mark a location configured to store a location mark, where in connection with loading system location mark is generated and stored in first memory cell to mark location and at least in second memory cell to mark location in other processor and is replaced each time when system is loaded; and a first execution core for executing a first instruction to create a first secure execution environment and execution from first secure execution environment of a second instruction for reading a location mark from first memory cell to mark location; and an agent for reading a location mark from second memory cell for marking a location associated with second secure execution environment in a second processor.
EFFECT: technical result is suppressing attack on communication line between secure execution environments.
