Research on the security model of mobile application

Security problem of mobile application is a great challenge that mobile internet facing nowadays. Traditional detection and protection methods can´t protect users from the emergence of a large number of malwares well, nor can they prevent normal applications from being decompiled and repacked by hackers. In that case, this paper proposes a security model of mobile application which includes two main stages. First, static and dynamic analysis technology are combined together and a double- staining algorithm is proposed to catch application behaviours so as to improve the accuracy of analysis. Then a reinforce framework for mobile application is proposed based on encryption and custom loader. The proposed model can not only detect whether applications are malicious, but also protect apps from being tampered by malicious developers, which will promote the development of security system of mobile internet.
