Double-system storage and starting method for nationalized tablet based on nationalized operating system

Abstract

The invention relates to a double-system storage and starting method for a nationalized tablet based on a nationalized operating system and relates to the technical field of an operating system. For the nationalized tablet equipment, the invention designs a double-system storage and starting method supporting the nationalized operating system, and the requirement of an autonomous controllable system is satisfied; through verification of a USB (Universal Serial Bus) key, a high safety level system is transparent to a low safety level user; the double systems are stored in different interface storage equipment to meet different demands of different application scenes on storage capacity and access speed. The method enables the double systems to separate physically, abundant application software of an android system can be utilized, the autonomous controllable nationalized operating system stored with important data can be selected and utilized according to the user safety level, and thehigh safety of information is guaranteed; by use of the storage equipment with different interfaces, the different requirements of the system on the storage capacity and the read-write performance aresatisfied.

Description

technical field [0001] The invention relates to the technical field of operating systems, in particular to a method for storing and starting a domestic flat panel dual system based on a domestic operating system. Background technique [0002] With the development of national and military informatization construction and independent controllable construction, the application scenarios of tablet devices are increasing, and higher requirements are put forward for the safety and operability of domestic tablets. The existing domestic tablet system can no longer meet the needs of multi-scenario applications, and dual systems have become a solution to multi-scenario applications. [0003] At present, domestic tablets generally use non-secure operating systems such as Android and Ubuntu as dual systems, and the system security is not guaranteed. You can directly enter any system after booting, without distinguishing the security level of the system, and lacking the matching between...

AI Technical Summary

Problems solved by technology

[0004] This dual system composed of non-secure operating systems stored on a single storage device does not use a domestic operating system to achieve the independent controllability requirements of key software and hardware, and the security is poor; there is no distinction between user security levels, and the dual system is safe for all users. It can be seen that the two systems are stored on different partitions of embedded multimedia cards with limited capacity, which cannot meet the different requirements for storage capacity and access speed in different application scenarios
