Risk Analysis Using Petri Nets of SET Protocol in Electronic payment system

摘要

In this paper, we are proposed a detected risk system after analyzed SET protocol using the Petri nets. We are shown the risk and detected points in SET protocol after checked the flow diagram of each functions in SET. We show 5 levels for detect and show a protect each models as authority level, purchase request, payment authorization and settlement exchange level, respectively. We used Visual Object Net++ for analyze the properties of Petri nets model.
