FIELD: information technology.
SUBSTANCE: invention relates to computer engineering, and generally to computer security. The method of providing for protected input comprises stages on which: a data stream entered by a user is received from a trusted input device in a second program execution environment; the received stream is sent from the second program execution environment to a protected program execution environment; determination is made of whether the protected program execution environment is in standard input mode; the initial data stream entered by the user is sent to the protected program execution environment based on the input mode of the latter; if the protected environment is in standard input mode, then at least the first part of data entered by the user is sent to the second program execution environment; determination is made of whether the data entered by the user contain user instruction for highly reliable input mode (NIM) and if so, and the protected program execution environment is not in highly reliable input mode, the protected program execution environment is switched to highly reliable input mode.
EFFECT: increased security level of computers.
