The SIREN project (Secure, Interoperable, UAV-assisted, Rapid Emergency Deployment Communication and sensing Infrastructure) implements a secure, distributed, open, self-configured and emergency-aware network and service platform for automated, secure and dependable support of multiple mission critical applications in highly demanding and dynamic emergency environments.

In emergencies or disasters a key support factor for situation awareness, decision making and response is to provide a secure and dependable network infrastructure that aggregates connectivity over all available heterogeneous wireless broadband access technologies, including those employed for commercial network access. The infrastructure must be able to adapt to mission critical application requirements and to enable immediate and robust communications among command centres, rescue workers and the affected population.

Existing civil protection and emergency response systems do not take advantage of commercial network infrastructures, since they are not typically designed to be relied upon in the event of major extrinsic failures and are thus deemed potentially unfit to sustain the requirement of massive mission critical operations [1].

SIREN federates two existing platforms, REDComm and SecoCard, and develops a secure and dependable overlay network and service infrastructure that hides the heterogeneity of the underlying networks and supports the multiplicity of communication needs across different types of users and user groups in emergencies.

REDComm, which stands for Rapid Emergency Deployment Communication, is a trailer based communication node that utilizes several communication technologies in order to provide multiple communication services in emergency and crisis situations [2]. Such services include not only traditional communications of emergency response authorities, but also modern services to these authorities such as live video streaming and multimedia content sharing as well as public addressing and victim communication. A REDComm node includes a hybrid power source based on both renewable and non-renewable energy generators and batteries to provide electric autonomy. A pneumatic telescopic mast is installed to support communication antennas providing mobility and increased coverage range.

One or more REDComm nodes can be easily and quickly deployed anywhere to provide communication services. The usage of mesh networking forms a redundant, seamless, self-healing, backbone network that is able to route communication traffic dynamically over the most appropriate path and technology. Eight REDComm nodes have been designed and implemented by FORTH-ICS and will be evaluated in drills and real-life situations with the Hellenic emergency response authorities such as police, fire department, the national emergency aid center and the Region of Crete that participate in the REDComm project [1].

SecoCard is an intelligent - and at the same time highly secure - external token with its own screen and capacitive touch keypad, which communicates with a non-modified smartphone or tablet over Bluetooth or WiFi and runs all the security applications, while the smartphone or the tablet, respectively, just provides connectivity and their normal unshielded applications [3]. The dedicated hardware is not much larger than a few credit or key cards stacked on one another, and can operate with practically every new smartphone and tablet model being sold today or unveiled in the future by the mobile industry.

With the federation of REDComm and SecoCard, SIREN implements an integrated comprehensive security architecture based on dedicated security mechanisms, taking into account cross-layer considerations and multi-operator emergency environments. In terms of cryptographic functions, SIREN implements a family of key agreement methods with particular focus on password-based, weak to strong authentication associated with several multiparty contributory key agreement schemes.

SIREN is also inspired by the opportunities and threats to the security of individuals owing to the convergence of the cyber and physical world, especially in urban environments. Increasingly within such environments, the everyday life of people takes place around cyber-physical objects that are becoming smarter and more inter-connected. This creates the possibility of continual acquisition, correlation and analysis of information that can improve citizen security and safety. It is, for example, possible to combine surveillance camera information with human physiological data and incident alerts created by mobile phone users in order to establish the occurrence of incidents and reacting to them on the spot and in a personalized manner. At the same time, the closer coupling of the physical world with cyber systems creates new threats and risks for people. Access to the location of individual (or groups of) people may, for instance, trigger targeted actions against them, and mass surveillance can compromise the privacy of individuals. Risks and threats may also increase significantly if functions, critical for the security and safety of citizens, depend on a cyber-physical infrastructure and Smart City applications that are not well protected against attacks (e.g., jamming communications between emergency responders).

Enhancing these opportunities and managing the associated risks can be based on SIREN, which in the future will enable the development and runtime operation and management of different Cyber-Physical and participatory sensing applications, including aerial unmanned vehicles (drones), supporting the acquisition and sharing of security related information through the use of SIREN infrastructure. The SIREN platform will enable the development and runtime operation and management of such applications by offering an open and extensible set of integrated basic capabilities, with particular focus on emergency response and crisis management.
