SHIFT+M: Software-Hardware Information Flow Tracking on Multi-core

Provided by: UC AB
Topic: Hardware
Format: PDF
The authors designed, implemented and analyzed three distributed protocols for information-flow tracking on a multi-core message-passing architecture. In each they used asbestos style labels to provide protection from unauthorized communication. The protocols remove the reliance on a central repository for taint checking by adding a trusted library and hardware mechanisms at each core. They modeled the hardware and software of each protocol using Simics, a multi-core full system simulator and used micro-benchmarks to capture their respective performance with different communication patterns.
