A software protection framework for mobile devices

The software protection technology is the main component of modern software security technology. Generally, confusion and encryption methods are using in software protection technology to provide traditional desktop applications. But applications based on mobile devices are also faces with threats such as piracy and tampering. The security problem in existing applications for mobile devices will do far more harm to users than traditional virus, but there is no effective software protection security framework for them. A software application framework for mobile devices is proposed in this paper, and the white box decryption algorithm involved is improved. And it is analyzed in this paper the performance and security of the framework proposed, the operational efficiency of the improved encryption algorithm is verified.
