Secured compartment for transactions

摘要

Systems and methods that establish a secured compartment that manages sensitive user transactions/information on a user's machine. The secured compartment qualifies user interaction with the machine, and separates such qualified interaction from other user activity on the machine. A user is switched to such secured compartment upon occurrence of a predetermined event, such as in form of: an explicit request (e.g., a secure attention sequence); an implicit request (e.g., inference of user activities); and presence of a peripheral device that is bound to the secured compartment (e.g., a USB)—wherein such actions typically cannot be generated by an application running outside the secured compartment.

主权项

1. A computer implemented system comprising the following:
one or more computer-readable storage devices storing one or more components; and one or more processing units operably coupled to the one or more computer-readable storage devices, the one or more processing units adapted to implement the one or more components, the one or more components comprising:
an operating system component to handle a plurality of interrupts via a trusted path; anda switching component to, in response to a Trusted Computing Base (TCB) generated interrupt:
switch user interactions to a secured compartment of the one or more computer-readable storage devices, the secured compartment comprising a plurality of whitelisted applications and whitelisted network domains that are accessible only from within the secured compartment, wherein:
the TCB generated interrupt is captured in a kernel of an operating system stored in the one or more computer-readable storage devices and handled by the operating system component; andthe computer implemented system handles the user interactions within the secured compartment in a different manner than user interactions outside thereof; andprohibit user interaction within the secured compartment with an application or domain that is not one of the plurality of whitelisted applications or the whitelisted network domains.
