Embodiment Construction

[0047] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] In the research of the traditional RPMB partition usage scheme, the inventor found that since the secure storage device such as EMMC has only one RPMB partition, in actual application, the secure storage device will allocate the RPMB partition to an operating system for use. However, when multiple operating systems are running on the virtual system at the same time, if the RPMB partition is allocated to each operating system, data synchronization errors and data leakage problems will occur.

[0049] Based on this, the embodiment of the present application provides a method for accessing the RPMB partition of the replay protection memory block. In order to support multiple virtual...

Abstract

The invention discloses a method and device for accessing RPMB partitions and related equipment. Specifically, the method and device are characterized in that: a plurality of virtual RPMB partitions are divided in a virtual service system, and a corresponding virtual RPMB partition is configured for each virtual machine; in use, the virtual service system receives a virtual RPMB partition access request sent by the virtual machine, and determines an access operation address of an actual RPMB partition in the secure storage device according to the identifier of the virtual machine and the access operation address of the virtual RPMB partition corresponding to the virtual machine in the virtual RPMB partition access request; and then, the actual RPMB partition access request is sent to the secure storage device, and the secure storage device can access the actual RPMB partition according to the operation address of the actual RPMB partition in the actual RPMB partition access request. Namely, the RPMB partition is virtualized, and the virtual RPMB partition is configured for each virtual machine, so that the access of a plurality of virtual machines is supported on the secure storageequipment with only one RPMB partition at the same time, and the synchronization and secure storage of data are realized.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device and related equipment for accessing RPMB partitions. Background technique [0002] With the upgrade of the car entertainment system, it is usually necessary to support the screen display and entertainment needs of multiple cars at the same time, so that the operations between passengers will not be affected by each other. In order to realize the above functions, it is necessary to support multiple operating systems (such as Android systems) on the same chip at the same time, and the secure data storage on each operating system needs to be supported by Replay Protected Memory Block (RPMB) partitions. [0003] At present, a secure storage device, such as an Embedded Multi Media Card (EMMC), has only one RPMB partition. In practical applications, the secure storage device will allocate the entire RPMB partition to an operating system for use. However, w...
