All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the terms "comprising" and "having" and any variations thereof in the embodiments and figures herein are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
The embodiment of the application discloses a port authentication method, a port authentication device, electronic equipment and a storable medium, which can improve the security of the electronic equipment. The following will describe in detail.
Referring to fig. 1, fig. 1 is an application scenario diagram of a port authentication method in one embodiment. As shown in fig. 1, the electronic device may include a first electronic device 10 and a second electronic device 20, where the first electronic device 10 may be a desktop computer, a tablet computer, a notebook computer, a mobile phone, etc., and the second electronic device 20 may be a desktop computer, a tablet computer, a notebook computer, etc. At least a central processor may be included in both the first electronic device 10 and the second electronic device 20. The computer systems in the first electronic device 10 and the second electronic device 20 may be Windows, linux, MTK, IOS or Unix, which are not particularly limited herein. A preload mode (preloader) port is provided in the first electronic device 10, and the preloader port is in a default off state. The first electronic device 10 authenticates the second electronic device 20 under the fast startup fastboot mode, and when the authentication result of the first electronic device 10 to the second electronic device 20 is that the first electronic device 10 passes, the first electronic device 10 opens a preloader port, and the second electronic device 10 uses a brushing tool to brush the first electronic device 10 through the opened preloader port.
Taking a mobile phone based on a chip developed by a concurrency department (MTK) as an example, a mainstream scheme at present is to close a preloader port of a user version of shipment, open a self-starting download mode (BootRom Download Mode, bore) port by default, write a public key abstract in an RSA encryption algorithm into the bore port by blowing a Service-Level agent (SLA) field in a one-time programmable memory (eFuse), and thus perform security verification of the bore port. The private key of the corresponding SLA encryption algorithm is required to be configured by using the MTK Flash brushing tool to finish brushing through the boom port, so that the private key is prevented from being leaked, and the safety of the boom port can be guaranteed theoretically. However, because the related codes of the boom ports are solidified in the platform chip, besides the verification scheme that the boom ports provided by the platform fuse the SLA, other complex verification schemes cannot be customized, and the default open boom ports have the risk of being cracked and verified by a hacker or bypassing the authorization.
Referring to fig. 2, fig. 2 is a flow chart illustrating a port authentication method according to an embodiment, which may be applied to the first electronic device 10 in the application scenario shown in fig. 1, where the first electronic device is provided with a preload port in a default closed state.

The Preloader port is in a default closed state, that is, in the case that the first electronic device does not perform security verification on the Preloader port, the Preloader port is in a closed state.
The first electronic device starts a fastboot mode in advance, and verifies whether the connected second electronic device has the right to access the system of the first electronic device in the fastboot mode. The fastboot is a firmware communication protocol for the second electronic device to perform writing, erasing/formatting, debugging and transmitting various instructions on the mobile phone firmware through the USB data line, and is also a command line tool in Android SDK Platform Tools of Google. A USB driver suitable for a mobile phone needs to be installed on a computer. Therefore, the fastboot mode is a line brush which is fast guided, and is a brushing mode for connecting the mobile phone by using the USB data line.
220. And when the authentication result of the second electronic equipment is that the second electronic equipment passes, opening a preloader port so that the second electronic equipment uses a brushing tool to brush the first electronic equipment through the preloader port.

In the case that the first electronic device authenticates the second electronic device, that is, the first electronic device verifies that the second electronic device has the right to access the system of the first electronic device in the fastboot mode, the first electronic device may automatically execute the related command, such as fastboot oem zeroflag clr command, to open the preloader port. After the first electronic device opens the preloader port, the second electronic device may use a brushing tool, such as a flash tool, to brush the first electronic device through the opened preloader port.

In some embodiments, the self-initiated download mode boom port of the first electronic device is set to a permanently closed state.
In this embodiment of the present application, the first electronic device is further provided with a boom port, and the boom port is in a permanently closed state, that is, the boom port cannot be opened. Because the boom port is a brush port which is cured in the chip by default on the system-in-chip and has higher authority, the boom port is permanently closed, and compared with the way of permanently closing the preloader port and using the boom port to brush the first electronic device, other electronic devices cannot attack or maliciously brush the first electronic device through the boom port with higher authority, and the safety of the electronic device is further improved.

In some embodiments, when the second electronic device completes the brushing of the first electronic device, the first electronic device reenters the fastboot mode, and the second electronic device is authenticated again in the fastboot mode.
In this embodiment of the present application, before the first electronic device re-authenticates the second electronic device to re-close the preloader port, the first electronic device needs to re-enter the fastboot mode to re-authenticate in the fastboot mode. The security of performing the re-authentication process in the fastboot mode can be improved.
340. And closing the preloader port after the second electronic device is authenticated again.
In the embodiment of the present application, if the result of the second electronic device re-authentication by the first electronic device is that the second electronic device does not pass, that is, the first electronic device verifies that the second electronic device does not have the right to access the system of the first electronic device in the re-authentication process in the fastboot mode, then the first electronic device does not operate the preloader port, so that the preloader port is kept in an open state.
If the result of the authentication of the first electronic device to the second electronic device is passing, that is, the first electronic device verifies that the second electronic device still has the right to access the system of the first electronic device in the process of re-authentication in the fastboot mode, then the first electronic device may automatically execute a related command, such as a fastboot oem zeroflag set command, to close the preloader port, so that the electronic device cannot access the system of the first electronic device through the preloader port.
By adopting the embodiment, the preloader port can be closed again after the machine brushing is completed, so that other devices are prevented from attacking or maliciously brushing the first electronic device through the preloader port, the first electronic device authenticates the second electronic device again before closing the preloader port, and the safety of the closing process of the preloader port can be enhanced.
