Description

1.TECHNICAL FIELD

[0001] The application belongs to the technical field of computer software security, and particularly relates to a Python script software encryption running device. 2.BACKGROUND

[0002] Python computer script programming language is widely used in network operation and maintenance, image processing, big data, cloud computing and AI artificial intelligence and the like, but the inherent source code interpretation running mode of the script language leads to the fact that the Python script program is easy to be tampered with and copied, and the source code integrity and security cannot be ensured, which causes loss to developers and users, in order to effectively solve the above problems, the application provides a Python script encryption running lock.

[0003] The current software encryption technology mainly includes dongle key authentication technology, file reading and writing encryption technology and Python transcoding and compiling technology.

[0004] A Chinese patent with the patent number CN101996293A discloses a software authentication method based on a dongle, which comprises the following steps: binding software with a dongle; detecting whether the dongle bound with the software is accessed each time the software is started, if not, access is denied, if yes, detecting whether the use state of the dongle is a used state, if not, marking the used state in the dongle and allowing access, if yes, detecting whether the authorization information can be obtained from the host running the software, if yes, allowing access, otherwise, denying access. The technology can reliably protect binary executable files and Python interpreter software, but Python script is a source code file, users can view and modify it and normally run it on the public unencrypted Python interpreter software, so the technology cannot effectively protect Python script.

[0005] A Chinese patent with the patent number CN1725196A discloses a computer data encryption protection and read-write control method, which adopts a universal serial bus dongle or software identity authentication and sector-level read-write interception method to realize encryption of hard disk data, the process is to intercept all read-write operations by the sector-level read-write interception method, to perform encryption and decryption conversion in the encryption core, and to realize encryption and read-write control of hard disk data under the condition that the corresponding identity authentication exists. The technology can encrypt script files and effectively protect user programs in a non-running state, but since Python script must be decrypted and imported into the interpreter to be normally run, the source code can be obtained by using the public MetaPathFinder import hook function or the source code can be obtained by directly intercepting the imported file and then using uncompyle6 and the like to decompile, so the technology cannot effectively protect Python script programs.

[0006] Python transcode compilation technology converts Python scripts into C / C++ language, and then compiles them into binary programs, such as Cython, Nuitka packaging and compiling software, etc. Python script programs can be compiled into executable files, which have good protection effect. However, due to the need for complex C / C++ development tool chain support, Python programmers without C language development experience find it difficult to use. At the same time, due to the rapid development of Python language, the version is updated frequently, and the transcode compilation software technology is difficult to develop, the development cycle is long, and it is difficult to keep up with the development of Python, causing serious reliability and compatibility problems, which cannot be applied to large projects and rapidly developing AI artificial intelligence, big data and other technical fields.

[0007] With the development of integrated circuit technology, SoC (System on Chip) chip products have been widely used in industries including mobile phones, Internet of Things, AI artificial intelligence, etc. Among them, the Chinese patent No. CN111506540A discloses a hardware programmable heterogeneous multi-core system on a chip. The system on a chip combines multi-core DSP, multi-core MPU, GPU, FPGA and numerous IP components through on-chip high-speed bus interconnection network to form a hardware programmable, multi-core heterogeneous system on a chip with the characteristics of small size, low power consumption, rich IP component resources and high running efficiency, providing a hardware basis for implementing chip-level Python interpreter firmware. 3. SUMMARY

[0008] The purpose of the present application is to write user core Python script programs into the SoC chip in the lock for encrypted running, so that the external code is invisible, thereby preventing user core Python program source code from being leaked and ensuring the integrity and security of Python script programs.

[0009] The present application is implemented as follows: a Python script encrypted running lock (110) comprising a data interface (130), an SoC chip (150), a Python interpreter firmware (140), and a Python drive plug-in (230), wherein the SoC chip (150) is configured to burn the Python interpreter firmware (140), run user core Python script programs (120), and connect the Python drive plug-in (230) and the Python interpreter software (240) installed in the computer (210) through the data interface (130), to realize cooperative running with the computer Python program (220).

[0010] Since the user core Python script program (120) runs on the SoC chip (150) in the Python script encryption running lock (110) and is not imported into the computer, the existing decompilation tools, hook class functions and file interception technologies cannot obtain the user core Python script program. When the program is running, the user core Python script program (120) performs a SHA256 integrity check on the Python program (220) in the computer, thereby ensuring that the Python script program is complete and reliable and preventing malicious tampering and copying. 4.
