Operation Refinement in Trusted Component Based on OR-Transition Colored Petri Net

摘要

The development and evolution of trusted software is the focus of attention in the fields of trusted software and software engineering at home and abroad. In view of its complexity and diversity, this article proceeds with component, which is the basic element of software architecture, and discusses the refinement of trusted component. Refine one of the operations and its local environment using OR-transition colored Petri net to achieve the purpose of gradual refinement.
