In the last 4-5 years, several major research efforts have sprung up aiming to design a set of potential next-generation Internet architectures. NDN and CNx are two such efforts based on the so-called information-centric networking (ICN) paradigm. They avoids IP's host-based, point-to-point networking approach in order to better  ccommodate new and emerging patterns of communication. NDN and CCNx treat data as a first class object, explicitly naming it, instead of its location. Unlike the current Internet which secures the communication "pipe" between hosts, they secure data -- a design choice that decouples trust in data from trust in hosts, thus enabling 
scalable communication mechanisms, such as data caching in routers to optimize bandwidth. NDN and CCNx pose many interesting security and privacy challenges, including: trust management, DoS resilience as well as content protection and privacy. 

This talk will start with a brief overview of CCNx/NDN and a summary of various security and privacy issues. The focus will be on network-layer trust management.
Motivated by the need to mitigate so-called "content poisoning" attacks, we explore the design of a generic ICN trust management architecture.

Gene Tsudik is a Chancellor's Professor of Computer Science at the UC Irvine (UCI). He obtained his PhD in 
Computer Science from USC in 1991. Before coming to UCI in 2000, he was at IBM Zurich Research Laboratory (1991-1996) and USC/ISI (1996-2000). His research interests include numerous topics in security, privacy and applied cryptography. Between 2009 and 2015, he served as the Editor-in-Chief of ACM Transactions on Information and Systems Security (TISSEC). He's a former Fulbright Scholar, a Fulbight Specialist, a Fellow of ACM, IEEE and AAAS, as well as a member of Academia Europaea
