Abstract
When the user is logged on to a processor running multiple virtual terminals and he presses the Secure Attention Key, the existing virtual terminal processes are not destroyed. Instead, the invention creates a new virtual terminal, establishes a trusted path for the new virtual terminal, makes the new virtual terminal the current virtual terminal, and then runs the trusted process in the new virtual terminal.
