چکیده

This chapter describes our approach to handle security in a complex Distributed Virtual Environment (DVE). The modules of such an environment all need to be concerned about security. An object-oriented model of a DVE allows us to capture security in an aspect-oriented fashion as a crosscutting concern among the multiple modules. As DVEs become more complex in content, distribution, and capabilities, the security requirement emerges as a key issue in their design and implementation. In order to control the software complexity, our strategy is to model and analyze the impact of security concerns on the functional model of DVEs via an aspect-oriented technique. This approach is appropriate to be applied at both the system design and modeling stages and provides guidance during the implementation stage. This chapter illustrates an aspect-oriented approach to the impact analysis of security concerns upon the functionalities of DVEs. A design-level security model for DVEs is provided to show how to weave security concerns into the models of DVE designs seamlessly.

Towards an Aspect-Oriented Framework in the Design of Collaborative Virtual Environments

The increasing complexity in the development of distributed system has promoted the appearance of new software technologies that complements compositional framework technology providing a high degree of separation of concerns. One of these approaches is aspect-oriented programming that introduces a new entity, the aspect, to model those features that cut across different components in the syste...

An Aspect-Oriented Approach to Distributed Object Security

In this paper we present a security framework for Bond, a message-oriented distributed object middleware for network computing. Bond Security Framework, BSF, allows developers to exercise performance-security tradeoffs and use the security model best suited for a specific application and for a given environment. BSF consists of an extensible core and a set of well defined security interfaces. A...

Separation of Distribution Concerns in Distributed Java Programming

Distributed design decisions in a distributed Java program crosscut the module structure of non-distributed concerns in the program. We propose a tool supporting aspect-oriented distributed programming, with which programmers can specify the distribution aspect of program simply and separately from non-distributed Java program, for enhancing the modularity of program. The aspect-weaver of this ...

Tier Aspect Model Based on Updatable Views

The tier aspect model addresses Aspect Oriented Programming (AOP) in the context of database applications. It is a new technique of separation of concerns through tiers implemented as virtual object-oriented updatable views. The code of an aspect related to particular objects is encapsulated within a separate view that overrides all generic operations performed on the objects. Aspect tiers form...
