The Dependable and Secure Distributed Systems Laboratory (DS2) at Purdue University focuses on designing distributed systems, networks and applications that are dependable and secure, while maintaining acceptable levels of performance. The work conducted within the lab explores how cryptographic protocols can be used to design distributed systems that are resilient to a wide-range of attacks. Of particular interest is the research of systems and network protocols operating under a Byzantine adversarial model. Such systems are often referred as intrusion-tolerant systems, since their approach is not to detect intruders, but rather guarantee correct service in spite of compromised participants.

Research areas of interest include:

• designing scalable architectures for dependable and secure network protocols, and distributed services
• investigate authentication and authorization of users, systems, and applications
• defining attack models for intrusion tolerance
• investigating fault-tolerance and security for new technologies such as ad hoc networks, cellular networks, hybrid networks, as well as pervasive systems.

The research conducted within the lab is funded by the Center for Education and Research in Information Security and Assurance (CERIAS), by the Defense Advanced Research Projects Agency (DARPA) , and by the National Science Foundation (NSF) .
