SYSTEM AND METHOD FOR PROTECTION FROM NON-TRUSTED SYSTEM CONTROL MODE CODE BY MEANS OF REDIRECTION OF SYSTEM MANAGEMENT MODE INTERRUPT AND CREATION OF VIRTUAL MACHINE CONTAINER

FIELD: system and method for ensuring possible execution of system management mode (SMM) code during protected operation in a microprocessor system. ^ SUBSTANCE: in accordance to the invention, interrupt processing system contains processor, first software which is contained in first virtual machine, and first processing means, which is contained in trusted software in second virtual machine. System management mode interrupt (SMI) is originally dispatched into processing means in protected virtual machine monitor (SVMM). System management mode interrupt may be then redirected to system management mode code, positioned in virtual machine (VM), which is under protected control of protected virtual machine monitor. Aforementioned redirection may be realized by means of allowing the protected virtual machine monitor to read and record data in the base system management (SM) register in the processor. ^ EFFECT: expanded functional capabilities. ^ 2 cl, 7 dwg
