A New Approach to Securing Audio Conference Tools

Named Data Networking (NDN), a recently proposed Internet architecture based on content-centric networking, is designed to secure data directly, instead of securing the communication channel between source and destination as in today’s Internet.
Given the novelty of this approach, application developers face challenges in its execution: what is the best way to secure data for various di fferent applications that are developed to run over NDN networks?
In this paper we describe the design of security mechanisms for Audio Conference Tool (ACT) and show how this approach can protect against common threats. We hope this design example will help the community’s understanding of security designs in content-centric networks.
