Research And Implementation Of A Cloud-Based Security System For Android Devices

In recent years, the mobile Internet is developing rapidly. Three aspects of intelligent mobile devices including hardware, software and bandwidth are improved. With mobile devices becoming more and more powerful, more and more users use mobile devices processing and transmitting data. The security problems of mobile devices will become increasingly prominent. Android operating system is facing the most serious challenges due to its openness and market share. Mobile device has its own characteristics compared with the PC. Due to its slow processing speed, small storage space, limited battery power and easily lost, the security measures to protect PC are generally not able to directly migrate to the mobile device. There are some limitations on the existing security products and researches for mobile devices. This paper designs and implements a cloud-based Android mobile device security system to improve the defects and shortcomings of existing security products and security researches. The main works of this paper are as follows:1. According to the researches on the safety status and security products in mobile devices, this paper analyzes the security issues faced by mobile devices and pointed out the deficiencies of the existing security products and security researches.2. By using a proxy server and cloud security technology, this paper proposes the use of the cloud to solve the current difficulties faced by mobile devices security products and then proposes a cloud-based mobile device security architecture.3. According to the proposed security architecture and the Android system architecture, this paper designs and implements a cloud-based security system for Android mobile devices.4. This paper confirms that the system is able to enhance the safety of Android mobile devices through solving the current problems faced by Android devices.
