Box 35, FIN-40014, Jyväskylä, Finland We are grateful to National Technology Agency of Finland, Agora Center (University of Jyväskylä), and cooperating companies (ABB, Metso Automation, TeliaSonera, TietoEnator, and Jyväskylä Science Park) of the SmartResource research project for the financial support.
23/03/2007A Security Framework for Smart Ubiquitous Industrial Resources2 Introduction Conventional approaches to manage and control security seem to have reached their limits in new complex environments. These environments are open, dynamic, heterogeneous, distributed, self-managing, collaborative, international, nomadic, ubiquitous, etc. We are currently working on a middleware platform focused on the industrial needs, UBIWARE. UBIWARE integrates Ubiquitous Computing with Semantic Web, Distributed AI, Security and Privacy, and Enterprise Application Integration. In this paper, we describe our long-term vision for the security management in complex multi-agent systems like UBIWARE, SURPAS. SURPAS aims at policy-based optimal managing of security measures.

23/03/2007A Security Framework for Smart Ubiquitous Industrial Resources5 The security implications of UBIWARE Existing security measures for the technologies on which UBIWARE relies are not in a mature stage. The security cannot be added to UBIWARE later. Security design has to be conducted throughout the development of UBIWARE. Characteristics of UBIWARE have different impact on security –Openness –Dynamics –Heterogeneity –Distributed nature –Collaborative social nature –Internationality –Self-management –Mobility –Ambient intelligence and pervasiveness
23/03/2007A Security Framework for Smart Ubiquitous Industrial Resources6 The Motivating Industrial Case Industrial impact, business benefits and security issues of UBIWARE for a domain of distributed power network management ABB is a global vendor of hardware and software for power networks. The power networks themselves are owned, controlled and maintained by some local companies. Four scenarios with potential add-value. –Information exchange between sub-networks –Transferring the tacit knowledge of humans to machines –New business model (Externalization of services) –Integration of contextual data for fault localization and risk analysis

Heterogeneity of applications Semantic request Semantic response DATA Information exchange between sub-networks How to elaborate flexible and expressive framework for the distributed, collaborative and policy-based management of security?

SURPAS: Including new, and reconfiguring existing, security mechanisms, for the optimal secure state in response to the dynamically changing environment.
23/03/2007A Security Framework for Smart Ubiquitous Industrial Resources12 The SmartResource platform UBIWARE relies on results from the SmartResource project (Proactive Self-Maintained Resources in Semantic Web, see http://www.cs.jyu.fi/ai/OntoGroup/SmartResource_details.htm) http://www.cs.jyu.fi/ai/OntoGroup/SmartResource_details.htm SmartResource technology gives a possibility to be smart to every resource in an industrial system. SmartResource is able –To proactively sense, monitor and control own state, –To communicate with other components, –To compose and utilize own and external experience and functionality for self-diagnostics and self-maintenance.

We presented –The SURPAS long-term vision of policy-based optimal management of security in multi-agent systems like UBIWARE. –The security implications of UBIWARE. –The motivating industrial case. –The SURPAS research framework. –The SURPAS abstract architecture. SURPAS as an ambitious target further demands –prototyping of ideas, –reference implementations, –industrial deployments and evaluations, –rigorous and convincing specification of advantages.
