There is an increasing need to perform Live Virtual and Constructive (LVC) based experimentation and training involving users and systems at different levels of clearance, classification and commercial boundaries. We have been researching this area, which has been fruitful in identifying requirements and innovative solutions. This thought leading paper shares our views on the challenges and discusses promising solutions to meet these requirements.

The paper discusses requirements from multiple perspectives, such as the users, infrastructures, applications, simulation systems and intellectual property. We highlight the challenges of protecting against leakage of sensitive information and also from the risk of compromising system integrity from malicious data.

A view on some of the costs, risks and limitation drivers are explored alongside the advantages and disadvantages of candidate architectures. We will be drawing on our experiences of delivering training and experimentation services, utilising modular flexible architectures that allow common, highly configurable content checking in conjunction with a variety of interface protocols.

The paper describes examples of how we have addressed the cross domain challenge and closes with a view of the remaining challenges.
