4. Background (1/2)
FP6 SECRICOM project ( ) “Seamless Communication for Crisis Management for EU safety”
Secure and trusted communication for crisis management and first responders
Secure Agent Infrastructure (SAI) concept was defined
Trust was established on the Trusted Platform Module (TPM) base and extended by Secure Docking Module (SDM)

5. Background (2/2)
FP7 REDIRNET project ( ) “Emergency Responder Data Interoperability Network“
Focus on data interoperability between autonomous agencies
REDIRNET should easily allow to share data among partner agencies
Conceptualization and enhancement of information collection

6. REDIRNET Architecture
REDIRNET Core
Main Switch connects end-points according to defined permissions
Data Storage contains backend data such as user information and end-point semantic description
REDIRNET Gateway
Container of REDIRNET plug-ins
Plug-in implements API to exchange data using Main Switch
Collaboration Portal
Social network like user interface that allows creating virtual partnerships

7. SAI ~ General-purpose information collection framework
Role of SAI in REDIRNET
SAI ~ General-purpose information collection framework
SAI Poll Management and Aggregation Service
operates on the template-poll-channel concept (discussed in the next lecture)
SAI Reply Collector platform
Providing services for collecting data from various data sources
SAI implements REDIRNET plugins to communicate with external resources

8. Reply Collector Platform
Reply Collector component hosts the agents
Agents are software entities running in agencies' computing environment.
Message buffer feature allows collected data to be processed and sent in batches
Reply Collector allows post-process collected data and providing information anonymization
XMPP Reply Collector
Implements XMPP protocol to communicate with mobile devices using Jabber server
XMPP communication minimizes the effect of intermittent network connection
Connects to REDIRNET partner agency to import remote data

Interpretation Poll description in JSON format
Data validation
User poll management
Actual poll instances
History of polls
Configuration interface
