Secure Network Component Architecture Model

In the Internet computing environment, clients usually invoke remote components to accomplish computation. As a result, many security problems are raised. Traditional network component architecture model focuses on business logic. It takes into little consideration the security problems when business logic is invoked. This paper proposes secure network component architecture model (SNCAM) to address them. It classifies clients according to their credibility levels on the component side. Next, we discuss the main idea of this paper, which is the security domain. To reduce the overhead introduced by the security mechanisms, a method called security agent is proposed. Finally, it quantitatively determines the performance cost introduced by the security mechanisms, and when to use the security agent
