               Preliminary Call for Papers

OVERVIEW

The 2nd International Workshop on Security Issues with Petri
Net sand other Computational Models (WISP2004) aims at promoting
research about theoretical foundations of security analysis and
design with formal methods and languages. WISP2004 starts from
the positive experience with WISP2003, held in Eindhoven within
the 24th International Conference on Application and Theory of
Petri Nets (ICATPN'03). WISP2004 is co-located and will be hold
just after the 25th International Conference on Application and
Theory of Petri Nets (ICATPN'04). Hence, original papers on the
application of Petri Nets for security issues are particularly
welcome. Also papers on security in other system models are
sought as well.

This year, WISP has a special focus in security aspects related
to coordination, composition and management of complex
e-services. Indeed, the rapid growth of the Internet as a
medium both for communication and computation fostered the
development of commercial products for distributed computation,
business process and workflow management. In such frameworks,
the information is seamless exchanged, accessed and manipulated
by many components and users with different goals, privileges
and obligations. Confidentiality, integrity and availability of
information need to be ensured during the whole lifetime cycle
of such e-services, even in presence of abnormal behavior.
Monitoring and enforcing security may be considered much more
challenging than in common communication protocols. Formal
methods communities, and henceforth the Petri nets one, may
successfully contribute also in this area to enrich the existing
set of tools and techniques and thus to enhance user confidence
on e-services.

Suggested submission topics include:
- security issues in orchestration and composition of e-services
- comparison and classification of security models
- formal definition and verification of the various aspects of
   security: confidentiality, integrity, authentication and
   availability
- information flow analysis
- security issues in probabilistic and real-time models
- mobile code security
- tools and techniques for the formal analysis of e-services
- applications to E/M-commerce
- case studies

WISP2004 is a one-day workshop sponsored by the IFIP WG 1.7 on
"Theoretical Foundations of Security Analysis and Design".
