Research of Cloud Security Communication Firewall Based on Android Platform

To solve communications security problems of smartphones, this paper analyzes today's firewall models' lopsided and mechanized characteristic and points out their defects and limitations. Then this paper proposes a new communications firewall model based on the Android platform innovatively with combination of today's hot cloud technology. By using a C/S architecture, black-grey list mechanism and cloud push and collecting system, this firewall can filter harassing phone calls and spam messages effectively and rapidly, as well as collect, process, share information dynamically. This system fully relieves the workload of the client and embodies the future firewall's development trend.
