- Securing Software by Enforcing Data-Flow Integrity
- Software attacks often subvert the intended data-flow in a vulnerable program. For example, attackers exploit buffer overflows and format string vulnerabilities to write data to unintended locations. This paper presents a simple technique that prevents these attacks by enforcing data-flow integrity. The paper also describes an efficient implementation of data-flow...

- Energy-Efficient Medium Access Control
- Medium access protocols for wireless sensor networks trade off performance (latency, throughput, and fairness) for cost energy consumption. They do so by turning off the radio for significant amounts of time reducing the energy wasted by idle listening, which dominates the cost of typical WLAN-based MAC protocols. Other sources of...
