Twitter in Disaster Mode: Security Architecture

Recent natural disasters (earthquakes, floods, etc.) have shown that people heavily use platforms like Twitter to communicate and organize in emergencies. However, the fixed infrastructure supporting such communications may be temporarily wiped out. In such situations, the phones' capabilities of infrastructure-less communication can fill in: by propagating data opportunistically (from phone to phone), tweets can still be spread, yet at the cost of delays. In this paper, the authors present Twimight and its network security extensions.
