Designing Security for a Future Internet Architecture: The Case of Named Data Networking

The Internet was developed in 70s by taking the telephony as the only example of effective global-scale communications. Although the packet switching was a phenomenal success, the communication paradigm it focused on has always been similar to that of telephony: a point-to-point conversation between two entities. The world has changed dramatically and the Internet use has evolved to be very data intensive. Unlike its early days, the Internet traffic is dominated by content distribution and retrieval today. To keep up with the change, efforts to design new Internet architectures have taken off globally within the last few years and have been attracting substantial research investment.

In Named Data Networking (NDN) project, one such highly collaborative research effort, we investigate a new architecture that names data instead of their location (hosts). By transforming data into a first-class entity and decoupling location from identity, security and Access, NDN enables several radically scalable and resilient communication mechanisms such as in-network caching and multi-path routing. Moreover, it provides a better security groundwork for applications and privacy guarantees to its users. In this talk, I will provide a brief introduction to the NDN architecture, discuss some of the security challenges we have faced during its design and provide insights to some of our ongoing research.

Bio: Ersin Uzun is a researcher and the manager of security research group at Palo Alto Research Center (Xerox PARC). Before joining PARC, Ersin held short-term researcher affiliations with Nokia Research Center, HP Labs and INRIA; co-founded a startup focusing on secure email solutions and provided security consultancy to various technology firms for 5+ years. Ersin has served in program committees of many security conferences/workshops including Financial Cryptography, ACM WiSec, ACNS, CANS, NpSec and been a regular reviewer for various journals including IEEE TMC, ACM TISSEC and JCS. Ersin received his Ph.D. in Computer Science from University of California, Irvine and his current research interests include systems and network security, applied cryptography, privacy protecting technologies and usable security.
