Duke Computer Science Colloquium

Lunch will be served at 11:45 AM.

With the increase of safety-critical traffic on the Internet, a challenge is to provide high availability in the presence of adversarial actors. The SCION next-generation network architecture has been explicitly designed for security and scalability, applying new ideas and novel concepts for achieving highly resilient control-plane operation and inter-domain end-to-end communication in the face of active attacks. SCION has been in production use for critical infrastructure communication since 2017, with expanding deployments and use cases since then. Operating side-by-side with today's Internet, SCION offers a communication fabric that is largely fault-independent from today's BGP-based infrastructure.

Given this backdrop, this talk will highlight use cases, technical and business aspects of SCION that provide security properties such as geo-fencing and path validation and enable new business models for IPSs. We will also discuss interoperability, how the fault-independence with today's infrastructure is achieved, and how the deployment and co-existence with today's infrastructure is accomplished. Ultimately, we cover the importance of open-source implementations, communities, IXPs, and the SCION Association for the success of a next-generation network architecture.

Adrian Perrig is a CS Professor at ETH Zürich, Switzerland, where he leads the network security group. He is also a Distinguished Fellow at CyLab, and an Adjunct ECE Professor at CMU. He earned his MS and PhD degrees in CS from CMU. He is a recipient of the ACM SIGSAC Outstanding Innovation Award, and is an ACM and IEEE Fellow. Adrian's research revolves around building secure systems, and his group is currently working on the SCION secure Internet architecture.
