SmartSiren

摘要: Smartphones have recently become increasingly popular because they provide "all-in-one" convenience by integrating traditional mobile phones with handheld computing devices. However, the flexibility of running third-party softwares also leaves smartphones open to malicious viruses. In fact, hundreds smartphone viruses emerged in past two years, which can quickly spread through various means such as SMS/MMS, Bluetooth and IP-based applications. Our own implementations proof-of-concept on Windows Mobile confirmed vulnerability this platform.In paper, we present SmartSiren, a collaborative virusdetection alert system for smartphones. order detect viruses, SmartSiren collects communication activity information from smartphones, performs joint analysis both single-device system-wide abnormal behaviors. We use proxy-based architecture offload processing burden resource-constrained simplify collaboration among When potential virus is detected, proxy quarantines out-break sending targeted alerts those immediately threatened demonstrated feasibility Dopod 577w smartphone, evaluated its effectiveness using simulations driven 3-week SMS traces national cellular carrier. results show that effectively prevent wide-area outbreaks affordable overhead.
