Disclosed is a description-entropy-based intelligent detection method for a big data mobile software similarity. The method comprises the following steps: acquiring a path of mobile software, and reading a file of the mobile software according to the path; performing preliminary reverse engineering decompilation on the file of the mobile software to obtain function characteristics of each piece of mobile software; counting distribution of description entropy of each piece of mobile software by means of description entropy in the function characteristics; further integrating description entropy of each piece of mobile software, after integration, comparing description entropy distribution conditions among the mobile software, and carrying out similarity score calculation to obtain similarity scores among the mobile software; and outputting the similarity scores of all mobile software to obtain a mobile software similarity result. According to the method, a source code of the mobile software is acquired by means of decompilation, a function compression code is acquired, and then the description entropy is acquired; and the description entropy is used as an information amount for representing an object and used for similarity detection of the mobile software, thus greatly increasing the speed of intelligent calculation of software similarity.
