Example Embodiment

[0018] Aiming at the security problem of mobile platform applications, the present invention proposes a method for dynamically adding and unpacking applications, and perfects a set of solutions for the application of mobile platforms.

[0019] From the perspective of the general solution of the present invention, the method for adding and unpacking includes two parts: the original executable file of the Android platform application program, the packing step and the unpacking step. The packing step is to use an external packing tool to compare the original executable file. The file format structure of the execution file is analyzed and the source program is encrypted as shelled data; the unpacking step is to load and run the unpacked program in the memory of the mobile terminal before the application runs, and decrypt the shelled data after the original The executable file is loaded into the memory and runs normally. Although it is similar to the aforementioned traditional unpacki...

Abstract

The invention discloses a shell adding and removing method for Android platform application program protection. The method includes the shell adding step and the shell removing step for an original executive file of an Android platform application program. The shell adding step refers to the step that the file format structure of the original executive file is analyzed through an externally-arranged shell adding tool, and a source program is encrypted to form data with a shell. The shell removing step refers to the step that before the application program operates, a shell removing program is preferentially loaded and operates in a memory of a mobile terminal, source program decrypting is carried out on the data with the shell, and then the original executive file is loaded to the memory and normally operates. Due to the adoption of the technical scheme of shell adding and removing, innovative thinking and feasible technical solving ways are provided for application shell adding and removing under an Android platform, and the shell adding and removing method can be used for protecting the executive file of the mobile platform, prevent the program from being attacked by hacker means like decompilation, guarantee confidentiality of commercial software and protect user application safety.

Description

technical field [0001] The invention relates to a design of a mobile platform, especially an Android platform application program packing and unpacking method, which is realized by comprehensively utilizing software programming technology, program analysis technology, network service technology encryption and decryption technology and mobile communication technology. Background technique [0002] In some computer software, there is a program specially responsible for protecting the software from being illegally modified or decompiled. They generally take control before the program runs, and then complete their task of protecting the software. Just like the shells of animals and plants are generally outside the body as a matter of course (but then the so-called "seed-in-shell" shells also appeared). Because this program has many similarities with the shells in nature, based on the naming rules, everyone calls such programs "shells". Just like computer viruses and viruses in...
