Brian,
I just took a quick look at the Object Filter project page. It is very similar to what I am doing for my thesis. I have implemented a dynamic Access Control model where access is permitted or allowed according to a scripted scenario. Essential the permissons are granted according to the following criteria:
Runtime type of the Caller
Runtime type of the receiver
Method name
Method Parameter types
and finally the state of the scenario. For instance in a cheque signing scenario, the cheque drafter might have permission to call the setAmount() method on the cheque object just after the cheque object has been created, but he loses this permission after the signCheque(Signature)method has been called by the supervisor.
If you are interested in knowing more, drop me a line at jason.furlong@rmc.ca
I noticed your reference to DARPA. Do you have any information about this as my work is being done independant of any organization.
Jason
