Estimating the term…
To provide a memory access control system in which partitions, which are divided memory areas generated in a device, can be independently managed. In response to access to the divided memory areas, which are a plurality of partitions, various types of access control tickets are issued under the management of each device or partition manager, and processing based on rules indicated in each ticket is performed in a memory-loaded device. A memory has a partition, which serves as a memory area managed by the partition manager, and a device manager management area managed by the device manager. Accordingly, partition authentication and device authentication can be executed according to either a public-key designation method or a common-key designation method.
A memory access control system for a memory-loaded device having a memory in which a data file is stored, wherein:
A device management apparatus for executing device management of a memory-loaded device, said memory-loaded device including one or more partitions for storing a data file therein, which serve as memory areas managed by a partition management apparatus, and a device manager management area managed by said device management apparatus, said device management apparatus comprising issuing means for a partition registration ticket (PRT) as a memory access control ticket that allows partition creation processing or partition deletion processing for a memory of said memory-loaded device.
A partition management apparatus for executing partition management of a memory-loaded device, said memory-loaded device including one or more partitions for storing a data file therein, which serve as memory areas managed by said partition management apparatus, and a device manager management area managed by a device management apparatus, said partition management apparatus comprising issuing means for an access control ticket that allows access to a partition generated in a memory of said memory-loaded device.
A memory-loaded device having a memory in which data can be stored, wherein:
A memory access control method for a memory-loaded device having a memory in which a data file is stored, wherein:
A program storage medium for providing a computer program for executing memory access control processing on a computer system, said memory access control processing being performed for a memory-loaded device having a memory, said memory including one or more partitions for storing a data file therein, which serve as memory areas managed by a partition manager, and a device manager management area managed by a device manager, which serves as a manager of said memory-loaded device, said computer program comprising:
