Mapping CRC Card into Stochastic Petri Net for Analyzing and Evaluating Quality Parameter of Security (TECHNICAL NOTE)

CRC cards are unconventional methods for identifying and describing classes, behavior and their responsibilities and collaborators of class. Representation of three categories of class, responsibilities and collaborators can give proper image of the scenario. These cards are effective method for analyzing scenarios. With all positive features of CRC cards, these cards have some weaknesses such as failure to show details of operations and failure to evaluate them. These weaknesses guide us to model and evaluate these cards using petri nets. Basis of petri nets is on graph. In addition, these petri nets have mathematical structure and definitions, they have graphics. One of the other important characteristics of petri nets is their applicability which can be used for evaluating behavior and efficiency of a system. Therefore, our goal in this paper is to map CRC cards into stochastic petri net for evaluating and analyzing quality parameter of security.
