Problems solved by technology

If only the UID is bound, but the protection program is still inside the chip, it is easier to bypass the protection program to obtain the source program of the MCU
If you add some advance operations before binding the UID, for example: first load the special code to the chip, and then cooperate with the protection program to protect the source code program, but this method is more cumbersome
[0004] Therefore, the method for protecting the source code program of the MCU in the prior art is either low in security or cumbersome to operate, and cannot simply and safely prevent the source code program of the MCU from being plagiarized and copied.

Abstract

The embodiment of the invention provides a target application running method and device and a storage medium. According to the technical scheme of the target application running method and device and the storage medium, whether a target application comprises an encryption program or not is judged, if yes, the encryption program is run, a secret key is generated, then the encryption program is erased, and the step of judging whether the target application comprises the encryption program or not continues to be executed; if not, the secret key of the target application is verified, when the secret key passes the verification, the target application is operated, and the source code program of the MCU can be simply and safely prevented from being plagiarized, copied and operated.

Description

【Technical field】 [0001] The present invention relates to the technical field of information security, in particular to a target application running method, device and storage medium. 【Background technique】 [0002] At present, the protection measures for the source code programs of most Micro Control Units (MCU) in the market are to set the read protection level of the chip to prevent the source code programs from being read through the Serial Wire Debug (SWD) interface, but through a certain Technical means can still obtain the source program of the MCU. [0003] Another method of protecting the source program of the MCU is to bind the unique identifiers (Unique Identifiers, UID) of the MCU, and determine whether it can work by performing a verification operation on the native program. If only the UID is bound, but the protection program is still inside the chip, it is easier to bypass the protection program to obtain the source program of the MCU. If you add some advanc...
