As part of its Future Internet Architecture (FIA) program, the National Science Foundation (NSF) Directorate for Computer and Information Science and Engineering (CISE) has awarded the funding for four new projects. According to the NSF, "These awards will enable researchers at dozens of institutions across the country to pursue new ways to build a more trustworthy and robust Internet."
A team of Carnegie Mellon University (CMU) researchers will lead one of these four projects, a three-year, $7.1 million effort dubbed eXpressive Internet Architecture (XIA). The CMU team, headed by Principle Investigator (PI) Peter Steenkiste will include CyLab's Technical Director Adrian Perrig as well as several other CyLab researchers, including David Andersen, Srinivasan Seshan and Hui Zhang. They will be collaborating with fellow researchers at Boston University and University of Wisconsin (Madison).
"The eXpressive Internet Architecture (XIA) addresses the growing diversity of network use models, the need for trustworthy communication, and the growing set of stakeholders who coordinate their activities to provide Internet services. XIA addresses these needs by exploring the technical challenges in creating a single network that offers inherent support for communication between current communicating principals--including hosts, content, and services--while accommodating unknown future entities. For each type of principal, XIA defines a narrow waist that dictates the application programming interface (API) for communication and the network communication mechanisms. XIA provides intrinsic security in which the integrity and authenticity of communication is guaranteed. XIA enables flexible context-dependent mechanisms for establishing trust between the communicating principals, bridging the gap between human and intrinsically secure identifiers. This project includes user experiments to evaluate and refine the interface between the network and users, and studies that analyze the relationship between technical design decisions, and economic incentives and public policy."
