DEVICE TO CREATE TRUSTED EXECUTION ENVIRONMENT FOR SPECIAL PURPOSE COMPUTERS Russian patent published in 2015 - IPC G06F21/30 G06F21/50 G06F12/14 

FIELD: information technologies.

SUBSTANCE: device to create trusted execution environment and protection of information against unauthorised access (UAA) comprises a managing microcontroller, a non-volatile flash-memory, non-volatile fast memory, fast electronic key, a buffer station based on a flash-memory microchip with SPI interface, a unit of switches to select device operation mode. The device is made in the form of a separate autonomous unit, and additionally includes a universal slot of PCI Express M.2 Specification standard, through which interfaces are realised for device interaction with the computer mother board, a converter of a chipset signal level, included into composition of the fast electronic key, a device for blocking and control of primary power supply of the computer, which is independent on the chipset, and an interface of mother board model identification for automatic tuning of parameters of device interaction with it.

EFFECT: increased efficiency of protection against unauthorised access to hardware and software components and to information stored and processed in a PC.
