Terminal

Abstract

The invention provides a terminal which comprises first processors, second processors, constraint external devices and non-constraint external devices. The first processors are used for processing private data in the terminal; the second processors are used for processing non-private data in the terminal; the constraint external devices are connected to the first processors; the non-constraint external devices are connected to the second processors; configured closed forwarding interfaces of the first processors or configured closed forwarding interfaces of the second processors can be respectively connected with peripheral interfaces, so that the second processors or the first processors can be connected with the constraint external devices or the non-constraint external devices and interact with the constraint external devices or the non-constraint external devices. According to the technical scheme, the terminal has the advantages that the private data and the non-private data in the terminal can be physically separately processed, so that the private data can be assuredly prevented from being acquired by unsafe application programs, and the safety of the terminal can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular, to a terminal. Background technique [0002] Such as figure 1 As shown, many peripheral devices (ie, external device 102 ) are installed in the terminal, such as a display screen, a touch screen, a camera, keys, a communication module, a sensor module, and the like. In related technologies, only a single processor ( figure 1 CPU shown in ), then the processor can send data to and receive data from any peripheral under the control of any application. When using, especially third-party applications from uncertain sources, these applications can easily control the only processor in the terminal to call private data, and even upload it to other terminals or servers arbitrarily. At the same time, since all data processed by the only processor is in the same memory space ( figure 1 RAM and ROM shown in ), so the above-mentioned application program is also very likely to...

Problems solved by technology

At the same time, since all data processed by the only processor is in the same memory space ( figure 1 RAM and ROM shown in ), so the above application program is also very likely to obtain private data from this storage space through simple cracking technology

Therefore, for the applications in the terminal, especially when some third-party applications in the terminal come from some hackers or personal information sellers with ulterior motives, it will lead to extremely insecure data such as user information in the terminal. state

[0003] Therefore, how to solve the data security problem brought by a single processor to the terminal has become a technical problem that needs to be solved urgently.
