Embodiment 1

[0038] According to the embodiment of the present application, an embodiment of a data processing system is also provided, wherein, based on the unclonability of the security chip, the system uses the key in the security chip to protect the data in the storage device, but the external interface does not No change, it is still the external interface used by the original storage device, thus ensuring that the storage device has anti-cloning capability without making hardware changes to the product.

[0039]Specifically, the structural diagram of the data processing system provided by this application is as follows figure 1 shown. Depend on figure 1 It can be known that the data processing system provided in this application includes: a controller 101 and a security chip 103 .

[0040] Wherein, the controller 101 is configured to obtain data to be processed and send the data to be processed to the security chip, wherein the data to be processed includes at least one of the foll...

Embodiment 2

[0091] According to the embodiment of the present application, an embodiment of a data processing method is also provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0092] Under the operating environment described in the above-mentioned embodiment 1, the application provides the following Figure 7 The data processing method shown. Figure 7 is a flowchart of the data processing method according to the present application, wherein, figure 1 The controller in the present embodiment can execute the data processing method provided by Figure 7 It can be seen that the data processing method includes the following steps:

[0093] In step S702, the first processor receives ...

Embodiment 3

[0110] Under the operating environment described in the above-mentioned embodiment 1, the present application also provides the following Figure 8 The data processing method shown. Figure 8 is a flowchart of the data processing method according to the present application, wherein, figure 1 The security chip in can execute the data processing method provided by this embodiment, by Figure 8 It can be seen that the data processing method includes the following steps:

[0111] Step S802, the second processor receives the data to be processed sent by the first processor.

[0112] It should be noted that the security chip is connected with the serial peripheral device interface SPI or general input and output interface GPIO of the controller.

[0113] In addition, it should be noted that the above-mentioned data to be processed may be data that the controller needs to read from a storage device or a cache, or may be data that the controller needs to store in a storage device o...

Abstract

The invention discloses a data processing system and method, a storage medium and a processor. The system comprises a controller used for obtaining to-be-processed data and sending the to-be-processeddata to a safety chip, and the to-be-processed data comprises at least one of data stored in a storage device and data needing to be written into the storage device; the safety chip is connected withthe controller and is used for encrypting and decrypting the to-be-processed data through a preset key to obtain processed data; the processed data are sent to the controller, and the preset secret key is stored in the safety chip; the controller is further used for executing an operation corresponding to the processed data; wherein the safety chip is connected with a serial peripheral equipmentinterface or a universal input / output interface of the controller. According to the invention, the technical problem that the animal networking device needs to be changed to enable the storage devicein the Internet of Things device to have the anti-cloning capability is solved.

Description

technical field [0001] The present application relates to the field of data security, in particular, to a data processing system, method, storage medium and processor. Background technique [0002] IoT (Internet of Things, Internet of Things) is an important part of the new generation of information technology, which can realize information exchange and communication between items. However, the storage device (for example, flash memory) in the IoT device is easily dumped by the programmer, so that when the entire IoT system can be physically accessed, the data in the storage device may be completely cloned by a malicious third party, resulting in Privacy data leakage. [0003] However, most storage devices in existing solutions do not support the anti-cloning function. Although some single-chip microcomputers with built-in storage devices support the anti-cloning function, the storage capacity of the storage devices is relatively small. The external interfaces and operati...
