Title: Named Data Networking: Data-Centric Future of the Internet and Internet Security

Abstract:

  Today's Internet is built on top of the IP architecture, which
  provides point-to-point communications among all computing devices
  in the world.  Many security solutions, developed later, are follow
  the IP's model by securing the communication channel between two end
  points.  However, the network usage today no longer fits the
  point-to-point conversation model with many more incompatible uses
  coming in the future.  Examples include content distribution,
  infrastructure-less and delay-tolerant mobile communication, and
  massive IoT device networking.  This mismatch between what IP's
  point-to-point delivery model provides and what applications need
  impacts both communication efficiency and efficacy of the security
  solutions.

  In this seminar, I will first introduce the Named Data Networking
  (NDN) architecture proposal that makes information the centerpiece
  for communication and security.  NDN retrieves data chunks using
  application-defined names, and each chunk carries a crypto signature
  that binds the name to its content.  Using DNS protocol adaptation
  to the NDN environment (NDNS) as an example, I will discuss
  advantages and challenges of NDN.  I will also introduce the concept
  of "trust schema" that formalizes trust relationships as a set of
  rules between hierarchical names of data and keys, enabling
  automating most of the key management, data signing, and data
  authentication tasks.
