With the rapid development of distributed object technology about CORBA、EJB,security technology is alsoextended to the environment of software object and component,CORBA security service effectively resolves the secu-rity problem in the distributed and heterogeneous environment. This article discusses the model of the CORBA securi-ty service,and references the interoperability technology on distribute object system,provides two security implemen-tation with different level.
As one of the popular interoperability technology, CORBA provides a distributed computing environmentfor enterprise application system. Although CORBA makes the development of the distributed S application moreconvenient and rapid, it does not define a separate process management service to manage and control the server pro-cesses of the ORB domain. Conforming to the CORBA 2. x specification, this paper analyzes the features and the ba-sic mechanisms of the process deployment for cluster servers in the distributed computing environment, and presentsa design of process management model by integrating SAD and SMD. In particular, the dynamic extension technologyand how SMD locates- SAD are also discussed in the paper.
