Embodiment Construction

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0045] Such as figure 1 The illustrated flow chart of the first embodiment of the method for running a Java program of the present invention includes:

[0046] Step S101: Start the current Java virtual machine, and load the dynamic link library file based on the Java virtual machine tool interface;

[0047] Specifically, the user needs to run the Java program and send an instruction to run the Java program to the electronic terminal. After r...

Abstract

The embodiment of the invention discloses an operation method of a Java program, which comprises the following steps of: starting a current Java virtual machine, and loading a Java virtual machine tool interface-based dynamic link base file; identifying whether the current Java virtual machine contains preset identification information according to the dynamic link base file; when an identification result is yes, normally starting the Java virtual machine to run the Java program; and when the identification result is no, exiting from a startup program. Correspondingly, the invention also discloses an electronic terminal. When the operation method of the Java program and the electronic terminal are used, the security of Java byte codes is guaranteed in a binary system grade and an attacker cannot acquire the byte codes, so that a source code of business software is radically protected against stealing and the core algorithm and trade secrets of the business software are more securely protected; and when the technical scheme of the invention is adopted, the characteristics of any Java do not lose, the protection of cross-platform Java byte codes is realized, deployment is simple and cost is low.

Description

Technical field [0001] The present invention relates to the field of electronic communication, in particular to a method for running a Java program and an electronic terminal. Background technique [0002] With the popularity and application of the Java language, more and more software is implemented using Java. Due to the dynamics and flexibility of the Java language, protecting its source code becomes very difficult. [0003] In the prior art, the source code can be easily extracted from its binary files with the help of decompilation. Therefore, any malicious user can use a decompilation tool, such as Jad (Application Development Contact Conference), etc. The software performs reverse engineering attacks, which can crack the authorized and protected program segments in commercial software and then distribute unauthorized copies at will. For experienced attackers, even without decompilation, they directly modify the binary bytecode to attack and obtain the source code. [0004] ...
