    SEPIA: Security-oriented PN Framework

    SEPIA: Security-oriented PN Framework

    Petri net framework for security related modeling and reasoning.

    SEPIA provides implementations for various types of Petri nets. Along Place/Transition-nets, it supports Petri nets with distinguishable token colors and defines coloured workflow nets, where coloured tokens are interpreted as data elements used during process execution. To support information flow analysis of processes, SEPIA defines so-called IF-Nets, tailored for security-oriented workflow modeling which enable users to assign security-levels (HIGH, LOW) to transitions, data elements and persons/agents participating in the process execution. SEPIA builds upon TOVAL (http://sourceforge.net/p/toval), JAGAL (http://sourceforge.net/p/jagal) and SEWOL (https://sourceforge.net/projects/jawl/). To use SEPIA, make sure these libraries are on the build path. SEPIA encloses the Multi Schema Validator (https://msv.java.net/) and isorelax (http://iso-relax.sourceforge.net/) The documentation can be found under http://doku.telematik.uni-freiburg.de/sepia.

    SMLEditor

    Prototype editor for the SDEM Mapping Language

    The Gateways Team of the Live-Virtual-Constructive Architecture Roadmap Implementation (LVCAR-I) effort is developing a set of tools that will support the gateway community. One of these tools is the Simulation Data Exchange Model (SDEM) Mapping Language (SML) Editor. The tool provides the ability to import two SDEMs in their native language and subsequently view the entities that need to be mapped between the two SDEMs. The SDEM Editor also allows the user to create these mappings and store the result in an SML file.
