Application program encryption method and device for Android-based system

Abstract

The invention discloses an application program encryption method and device for an Android-based system. When the Android-based system is powered on, an authorization service module is enabled, and an encryption driving module is requested to read SOC feature information; the encryption driving module reads the SOC feature information in an SOC module, conducts secondary encryption on the information through an AES encryption algorithm and an XOR encryption algorithm and then transmits the information to the authorization service module; the authorization service module decrypts the encrypted information through an AES decryption algorithm and the XOR decryption algorithm, judges whether the SOC module is authorized or not according to the decrypted information and stores an authorization result to allow an application program module to query; when the application program module runs, an authorization detection request is sent to the authorization service module, the authorization service module returns the authorization result to the application program module, and the application program module determines whether or not to withdraw from running according to the authorization result. Accordingly, the purpose that the application program module can only run on an authorized hardware platform is achieved, and the security of the application program module is greatly improved.

Description

technical field [0001] The present invention relates to the field of the Android system, and more specifically, the present invention relates to an application program encryption method and device based on the Android system. Background technique [0002] With the increasing popularity of smart terminals and the rapid development of network broadband, the mobile Internet era marked by the continuous enrichment of mobile applications and services has brought people a more convenient and intelligent digital life, and gradually penetrated into the details of offline life. . However, the potential information security problems in the open and flexible terminal system and its application may affect users, bearer network and other links. [0003] With the widespread use of the Android system, the Android application development market is becoming increasingly hot, and packaging parties obtain huge profits through illegal means such as cracking and decompiling applications, insert...
