The invention discloses a program reinforcing method and device based on an application program installation package. The method comprises the following steps: extracting a binary file from an application program installation package; determining a plurality of specific types of data contained in the non-code segment in the binary file; wherein the specific type of data comprises constant data andsymbol data; and performing encryption processing on the specific type of data by adopting an encryption algorithm matched with the type of the specific type of data. According to the scheme, throughencryption processing on the specific type of data in the non-code segment of the binary file, reinforcement on the application program can be achieved, so that the reverse difficulty of the application program is greatly improved, reverse analysis on the application program is effectively prevented, and code expansion of the application program is not likely to be caused. Moreover, the implementation process is simple an
