Description
Technical field
The invention belongs to field of mobile equipment, particularly relate to a kind of data transmission method and device.
Background technology
Operating system (OperatingSystem is called for short OS) is the operating system for managing and control mobile device hardware and software resource.Wherein, open operating system, for instance Android and iOS, can support to install and uninstall application program voluntarily, and user can download, by network, the application program oneself liked and install, to enjoy the intelligent experience that smart mobile phone brings.
A usual mobile equipment is only fitted into a type operating system, run the application program meeting its running environment accordingly, this brings some inconvenience to the application programs use on the mobile apparatus of some proprietary system, sometimes for making it to use on same equipment, hard mental and physical efforts are developed again suitable in development system version (such as Android), but this makes again follow-up maintenance cost height look forward to；Or the virtual machine of another operating system of operation support in an operating system, and run its application program on this virtual machine architecture, this can cause that specific application and the Application sharing running environment of the latter bring the misgivings of secure context.
In addition, there is open and increasing income property due to open operating system, the safety approach of second time exploitation is all as easy as rolling off a log to be cracked or evades, a large amount of wooden horses and virus can be hidden in some application software, steal user privacy information, make the information security of individual, property safety also be faced with serious threat.Threatening for these, the fail-safe software of mobile device operation system is typically with security sandbox, and the important information of protection user is from the infringement of these wooden horses and virus.Meanwhile, in same mobile equipment, the first hardware structure and the second hardware structure is adopted to constitute two physically-isolated operating system environment of hardware, to improve the safety of system.
But, in same mobile equipment, when adopting the first hardware structure and the second hardware structure to constitute the physically-isolated operating system environment of two hardware, it is impossible under the premise ensureing the first hardware structure safety, improve the application in the first hardware structure and access the convenience of network.Its reason is in that, it it is hardware physical isolation between first hardware structure and the second hardware structure, it is independent of each other between the two, when the external mixed-media network modules mixed-media operating in the first hardware structure directly accesses network, the safety of the operating system run in the first hardware structure can be reduced.Additionally, due to be absent from the transmission channel of inside between the first hardware structure and the second hardware structure, therefore the application in the first hardware structure cannot pass through the second hardware structure dereference network, is unfavorable for that improving application accesses the convenience of network.Therefore, mobile equipment under the premise ensureing the first hardware structure safety, cannot improve the application in the first hardware structure simultaneously and access the convenience of network.
Summary of the invention
The purpose of the embodiment of the present invention is in that to provide a kind of data transmission method and device, aim to solve the problem that in same mobile equipment, when adopting the first hardware structure and the second hardware structure to constitute the physically-isolated operating system environment of two hardware, under the premise ensureing the first hardware structure safety, the problem that the application in the first hardware structure accesses the convenience of network cannot be improved.
The embodiment of the present invention is achieved in that a kind of data transmission method, including:
Configure the data channel between the first operating system and the second operating system, described data channel is made up of the first data services operating in described first operating system and the second data services operating in described second operating system, and described data channel is the passage of transmission internal data；
Configuring dereference network function in described data channel, described dereference network function is:
Described data channel receives the networking request of trusted applications, and described networking request is sent by described first operating system；
Forward networking request extremely described second operating system of trusted applications；
Receive the networking data that described second operating system returns；
Forward networking data extremely described first operating system returned；
Wherein, described trusted applications is be applicable to the application program of described first operating system.
The another object of the embodiment of the present invention is in that to provide a kind of data transmission device, including:
Data channel configuration module, for configuring the data channel between the first operating system and the second operating system, described data channel is made up of the first data services operating in described first operating system and the second data services operating in described second operating system, and described data channel is the passage of transmission internal data；
Dereference network function configuration module, for configuring dereference network function in described data channel, described dereference network function is:
Described data channel receives the networking request of trusted applications, and described networking request is sent by described first operating system；
Forward networking request extremely described second operating system of trusted applications；
Receive the networking data that described second operating system returns；
Forward networking data extremely described first operating system returned；
Wherein, described trusted applications is be applicable to the application program of described first operating system.
In the present invention, configure the data channel between the first operating system and the second operating system, data channel configures dereference network function, solve in same mobile equipment, when adopting the first hardware structure and the second hardware structure to constitute the physically-isolated operating system environment of two hardware, under the premise ensureing the first hardware structure safety, the problem that the application in the first hardware structure accesses the convenience of network cannot be improved.The beneficial effects of the present invention is two aspects, one is the program that can run different operating system on the same device, has widened the range of application of mobile equipment, makes some specific applications to continue to run with；Its 2 first hardware structure does not have network data channels, outside cannot adopt the mode from network data channels injecting data or utilize the mode that there is leak protocol stack, first operating system is attacked, in addition, first hardware structure can obtain the network data of needs by data channel, therefore both ensure that the first hardware structure safety, and also improved the application in the first hardware structure and access the convenience of network.
