Abstract. Information technology and modern challenges in civil protection create many questions concerning infrastructure security and reliability. In particular, mobile communications and the spread of mobile phones among citizens offer new opportunities of fine-grained disaster management using location based services (LBS). At the same time, location based services are regarded as very privacy-invading, and are regulated in many countries by law.In our article, we analyze the requirements of a LBS based disaster management scenario and propose a solution on how to build a privacy-friendly, multilaterally secure disaster management infrastructure based on robust, mobile phone infrastructures with high reachability of citizens and the possibility to manage disaster specialists.

Disaster management using mobile telecommunication networks provides a new and attractive possibility to save human lives in emergencies. With this contribution, we present a possible disaster management system based on mobile telecommunication. In order to use such a system in the real world, security requirements such as availability, accountability, integrity and confidentiality have to be ensured by the disaster management system (DMS). We summarize these requirements and propose ways of addressing them with a multilateral secure approach. Using electronic signatures based on SIM-cards, we assure integrity, accountability and confidentiality of the notification messages. We also discuss how availability could be increased.

In recent years, natural disasters and terrorist attacks have been quite numerous, and broadly reported in the media. The tourism industry has been especially impacted by these emergencies. In order to mitigate the effects of such events, guaranteeing an adequate level of preparedness is essential. However, despite the extreme disrupting events that large-scale disasters such as tsunamis have had on tourism in specific areas, few tourism organizations have properly developed emergency strategies as an integral part of their business plans. Several national and supra-national initiatives are currently working on possibilities to employ mobile communication networks for emergency management systems. The success of such systems depends on users being familiar with the service though, which is difficult to achieve if the system is solely used for emergency management. Therefore, the authors propose a reference architecture that allows the integration of mobile value-adding services, allowing for broad usage outside of emergency cases and thus an increased familiarity. The authors also present a specific system design focusing on the case of large public events as an instantiation of the reference architecture, describe the implementation in some detail, and present the evaluation of the prototype implementation in a simulation study at a large public event.
