Interoperable Role-Based Single Sign-On-Access to Distributed Public Authority Information Systems

The key challenge for Incident Response Organizations is to gather sufficient information about the incident location: In large loss operations information has currently to be requested time-consumingly from different, distributed public authorities. Single-Sign-On Systems are still in progress of devolopment, but all existing systems have the lack of role based access control in common and are based on the functional uncorrelation of their users. In this paper we will present a novel interoperability concept and prototype implementation for a combined Single Sign On (SSO) and Role Based Access Control (RBAC) information system and show its effectiveness through evaluation by implementing it. Just through single operation it will enable the security forces to get shared and simultaneous realtime access to distributed databases of relevant public authorities such as registry offices or building authorities, where table of hydrants, plans of (gas) pipelines or video sequences are available. Beyond the secure system architecture the focus lies on the performance analysis and analytical proof of reliability for our novel mobile information system.
