1. a kind of device for dynamically carrying out safe division to resource, including:

  • Memory cell, it has multiple subregions, wherein, the first subregion in the multiple subregion is used to store independently of operation systemUnite the subregion of (OS), should have independently of operating system and virtual machine manager independently of the subregion of OS and be not by operationSystem and the performing environment of virtual machine manager influence, and the second subregion in the multiple subregion is used to store OS;

    AndThe explorer independently of operating system/virtual machine manager that firmware is realized, it arrives the multiple subarea managementProcessor, wherein, the explorer is used between first subregion and second subregion dynamically divide describedCycle of processor, and wherein, operation on the processor, the application program from second subregion can be from instituteState explorer and obtain key blob to access the data in first subregion, the key binary system is right greatlyAs it is being generated comprising application program, the embedded key for being only capable of being accessed by the explorer used by the explorerThe key of encryption.
