Problems solved by technology

[0003] However, because the Java program must meet the bytecode specification of the virtual machine, the compiled Java file still retains a large amount of information, which makes the Java program easy to crack and reverse, although there are special obfuscation tools. Avoid cracking and reverse engineering of Java programs
However, for attackers who are familiar with Java language features, these obfuscation tools do not have much defensive effect
[0004] For the problem of low Java code security, no effective solution has been proposed yet

Embodiment Construction

[0038] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0039] Considering that the existing Java code is insecure and easy to crack and reverse, and the C code is not easy to crack and reverse, if the more important Java code or the code that needs to be improved in security is converted into C code, and the normal Java code analysis and running requirements can effectively improve the securi...

Abstract

The invention provides a data processing method and device, and a program running method. The data processing method comprises the steps: obtaining a target program package, wherein a program code inthe target program package is written through a Java language; filtering the program code according to a preset filtering rule to obtain a filtered program code; and translating the filtered program code into a C language code. By means of the scheme, the technical problem that existing Java program codes are not high in safety is solved, and the technical effects of effectively improving the codesafety and improving the cracking difficulty are achieved.

Description

technical field [0001] The present application belongs to the field of computer technology, and in particular relates to a data processing method, a program running method and equipment. Background technique [0002] As one of the more popular development languages ​​at present, Java is widely used by developers. Compared with C language, Java programs have many advantages, such as: security, versatility, stability, etc. [0003] However, because the Java program must meet the bytecode specification of the virtual machine, the compiled Java file still retains a large amount of information, which makes the Java program easy to crack and reverse, although there are special obfuscation tools. Avoid cracking and reverse engineering of Java programs. However, for attackers who are familiar with the characteristics of the Java language, these obfuscation tools do not have much defensive effect. [0004] Aiming at the problem of low Java code security, no effective solution has b...
