I am looking forward to Defence Systems and Equipment International (DSEi), the world's largest fully integrated international defence exhibition, which is being held in London from 8-11th September 2009. In preparation for the event, I've been setting up some Wind River VxWorks MILS 2.0 demos on a Curtiss-Wright VPX6-185 board.
VxWorks MILS is Wind River's implementation of the Multiple Independent Levels of Security (MILS) security architecture, which can host applications running at different security classifications, including multilevel secure (MLS), on the same platform. VxWorks MILS is able to do this by implementing information flow control, data isolation, periods processing and damage limitation, whilst ensuring that data does not leak from one partition to another through either overt or covert channels. The demos also show how Wind River Workbench can perform concurrent debugging of multiple partitions, which is invaluable when developing multi-partition systems.
