Embodiment Construction

[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] In the first aspect, the embodiment of the present invention provides a linking method based on file structure design.

[0042] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the linking method based on the file structure design of the present invention.

[0043] In an embodiment of the linking method based on file structure design of the present invention, the linking method based on file structure design includes:

[0044] Step S10, generate the target files of different modules according to the file structure of the bytecode generated in the compiler, wherein the file structure includes: module header component, module application component, module constant component, module file component, module method component and the module index component;

[0045]In this embodiment, i...

Abstract

The present invention provides a linking method based on file structure design and a readable storage medium. The linking method based on file structure design includes: generating target files of different modules according to the file structure of the bytecode generated in the compiler; The target file generates a download script identifiable by the security module through a conversion tool; when a download instruction is received, the download script is downloaded and installed into the security module, wherein, during the download and installation process, according to the download script The file structure of different modules completes the linking of methods between different modules; when there is a method call request, according to the link of the method called by the request, jump to the physical address of the method called by the request to execute the method. The invention can reduce the volume of the file and improve the operation efficiency, and at the same time realize the same security feature as the security module designed by the file structure of the traditional Java language virtual machine.

Description

technical field [0001] The invention relates to the field of storage design for devices with limited resources, in particular to a linking method based on file structure design and a readable storage medium. Background technique [0002] On devices with limited resources but high security performance requirements, such as smart cards, Internet of Things security devices, and security modules, in the prior art, Java language virtual machines are integrated on embedded systems to realize local native methods. Provide the API interface of the Java language, and provide secondary development in the Java language. When the traditional Java language virtual machine provides secondary development in Java language, the same function, the target binary file generated according to the file structure design of the Java language virtual machine takes up more memory space than programming in C language. a lot of. And in terms of functional operation, since the traditional Java language...
