Community-Based Bidirectional Feedback System for Hybrid Worm Containment in Mobile Internet

Aiming at the problem that the existing worm containment methods can’t reply the mobile Internet worm attack which mixes long-range and short-range attack, this paper proposes a mobile Internet mixed worm bidirectional feedback and containment system based on community. The system consists of SIN (social information networks) containment unit and GIN (geographic information networks) feedback unit. The SIN containment unit is a type of online community quarantine strategy, which contains worms within the community by identifying the access nodes between communities and designing the corresponding worm label delivery algorithm. The GIN feedback unit collects the users’ short range communication records, GPS location data and the historical security information committed by SIN to realize the trust-assessment. Through feeding back the results to SIN containment unit, the GIN limits the next communication decisions of community internal nodes, accordingly reduces the spreading speed of worms inside the community and realizes the bi-directional loop between the SIN containment unit and GIN feedback unit. Simulation experiments have proved that the method proposed by this paper has feasibility and effectiveness.
