Embodiment Construction

[0035] Since the data format of the bytecode file compiled by the Java virtual machine strictly complies with the Java virtual machine specification, reverse engineering can reversely deduce the source code of the program by analyzing the data format of the bytecode file. For this, the existing technology proposes from different dimensions A variety of protection methods for Java applications, mainly including: localization technology, remote interface access technology and obfuscation technology. However, there are some problems with these technologies, specifically:

[0036] 1. Localization technology: This technology refers to first writing the Java source code, then compiling the Java source code into a Class file or building a jar package through a Java compiler, and finally using a localization tool to compile the Class or jar file into a binary native application. However, Java localization technology produces executable files in binary format, which will cause Java ap...

Abstract

The invention discloses a Java application program encryption method and device, and is applied to the technical field of electronics. The method comprises the following steps: determining a first Tagvalue sequence in a constant pool of a Java application program to be encrypted, and reordering Tag values in the first Tag value sequence to obtain a plurality of second Tag value sequences with different Tag value orders; and replacing the first Tag value sequence with the plurality of second Tag value sequences to form an encrypted Java application program. The technical problems of poor security of the Java application program and leakage of important algorithms and data in the prior art are solved.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a Java application program encryption method and device. Background technique [0002] Java is an object-oriented programming language launched by Sun that can cross multiple platforms and has the highest portability. It is also the most widely used, most feature-rich, and most powerful computer language so far. Java can be used to write various applications based on different platforms and systems, making it the most widely used development language, especially in the development of virtual machine programs. [0003] The Java development technology hides the complexity of the underlying technology and the characteristics of the machine and the operating system at the virtual machine level. The physical machine environments for running programs are different, while the Java virtual machine establishes a unified operating platform on different operating environments ...
