Summary : "The CRASH/SAFE project is building a network host that is highly resiliant to cyber-attack. One pillar of the design is pervasive mechanisms for tracking information flow. At the lowest level, the SAFE hardware offers fine-grained tagging and efficient support for propagating and combining tags on each instruction dispatch. The operating system virtualizes these generic facilities to provide the information-flow abstract machine on which user programs run. In this talk, we'll take a guided tour of (a simplified model of) the SAFE hardware and software and an end-to-end proof of noninterference for this model."
