Application reinforcement method and device, computing device, computer storage medium

Abstract

The invention discloses an application program strengthening method and device, a computing device, and a computer storage medium, wherein the method includes: for at least one function in the application program, determining a reference function block included in the function; Block, determining the instruction fragments that meet the preset fragment rules included in the reference function block; copying the instruction fragments that meet the preset fragment rules into at least two instruction fragments; before the instruction fragments that meet the preset fragment rules , adding a jump instruction for jumping to one of the at least two instruction fragments. By adopting this solution, it is possible to increase the difficulty of evading wasteful instructions and forged process branches during the reverse compilation process, confuse the reverse compilation logic of the program, increase the difficulty of reverse compilation, and realize the reinforcement of the application program.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for reinforcing an application program. Background technique [0002] With the continuous development of science and technology and society, the number of various applications is also increasing rapidly. However, program reverse developers or program reverse products can easily obtain the source code in the application program by decompiling the application program, so that the phenomenon of piracy and repackaging of the application program also emerges endlessly. At present, in order to increase the difficulty of application decompilation, anti-reverse compilation technicians often add fancy instructions to the program and / or forge process branches to confuse the program decompilation logic. [0003] However, the inventor found in the process of implementing the present invention that the above-mentioned methods in the prior art have at least ...

AI Technical Summary

Problems solved by technology

[0003] However, the inventor found in the process of implementing the present invention that the above-mentioned methods in the prior art have at least the following defects: for reinforcement methods such as adding flowery instructions in the program and / or forging process branches, reverse compiler personnel can pass a During the execution process, the position of the executed instruction is recorded, and other instructions that have not been executed are erased (such as Nope operation), and these fake process branches and waste instructions can be easily removed, and the application program cannot be hardened.
