This paper describes a generic model of matching that can be usefully applied to misuse intrusion detection. The model is based on Colored Petri Nets. Guards define the context in which signatures are matched. The notion of start and final states, and paths between them define the set of event sequences matched by the net. Partial order matching can also be specified in this model. The main ben...

Multifunction Vehicle Bus (MVB) is a critical component in the Train Communication Network (TCN), which is widely used in most of the modern train techniques of the transportation system. How to ensure security of MVB has become an important issue. Traditional testing could not ensure the system correctness.TheMVB systemmodeling and verification are concerned in this paper. Petri Net and model ...

With the rapid advances in computer science and technology, critical computer-based systems, such as those in aerospace, military, and power industries exhibit more complex dependent and dynamic behaviors, which cannot be fully captured by existing reliability modeling tools. In this paper, we introduce a new reliability modeling tool, called dynamic reliability block diagrams (DRBD), for model...

Currently,modeling for software is mostly semiformal, such as UML(Unified Modeling Language).The main problem is difficult to analyze semantics and verify correctness for a vital system.CPN(Colored Petri Net)as modeling and verification method provides formal semantics and a number of analysis techniques and tools.This paper presents an approach of formal modeling and validation for software pr...
