Mobile Ubiquitous Security Environment

We approach the problem as follows:

• Theory - We have an interacting automata theory that includes the ability of behaviors to wander from network node to network node.

• Abstract simulations - Mobile code behaviors are coded and tested in a Cellular Automata based visualization environment.

• High fidelity simulations - Promising approaches are integrated into the Virtual Internet Testbed (ns and nam). Multiple network configurations can be generated. The mobile code behaviors can then be integrated with IP network protocols and statistical evaluations performed.

• Prototype implementations - After exhaustive testing sith VINT simulations, we test our infrastructure protection algorithms on a live network isolated from the Internet. This makes use of our network pathology laboratory.
