Abstract

The invention discloses a method and apparatus for protecting application security based on a virtual machine. The method comprises the following steps: obtaining a code of an application, and judging whether each function in the code contains a preset protection identifier; if the function contains the preset protection identifier, compiling the function into an assembly instruction that is executed on the basis of the virtual machine; and linking execution logic of the virtual machine with the assembly instruction that is executed on the basis of the virtual machine to generate a target program of the application. In the scheme, the code in the function containing the preset protection identifier is virtually compiled through an operation environment of the assembly instruction corresponding to the application self-defined by the virtual machine, the entire virtual compilation process is irreversible and cannot be restored, therefore even if decompilation is performed on the virtualized assembly instruction, the obtained code is not the original code of the application, and thus the security of the code of the application is protected.

Description

technical field [0001] The invention relates to the field of software, in particular to a method and device for protecting application security based on a virtual machine. Background technique [0002] With the development of science and technology, the number of users of smart terminals has exploded, and many applications installed on smart terminals have gradually become an indispensable part of users' daily life. Application security has emerged as the biggest issue faced when using applications. Packing applications is the main protection technology currently used. Through packing, the application can prevent the application code from being disassembled and analyzed and dynamically analyzed to a certain extent, so as to ensure the security of the application. [0003] But all packers have the risk of being unpacked, and packers will inevitably affect program compatibility. In addition to packing, security hardening can also be performed on the application. However, i...
