METHODS AND APPARATUS FOR PROTECTING DOMAINS OF A DEVICE FROM UNAUTHORISED ACCESSES

摘要

The present invention relates to a machine implementation method for protecting target domains and source domains from unauthorized accesses. The machine implementation method includes the steps of: identifying exit call gateways including one or more exit access parameters and an exit transition command, wherein the exit access parameters limit the exit from the source domains; identifying the entry call gateways corresponding to the exit call gateways, wherein the entry call gateways include one or more entry access parameters and a transition command and the entry access parameters limit the access to the target domains; determining the compatibility of the entry and exit access parameters; and executing a context switch to the target domains from the source domains when the exit and entry access parameters are complied with.
