A new approach to securing audio conference tools

Instead of securing the communication channel between sources and destinations as in today's Internet, Named Data Networking (NDN), a recently proposed Internet architecture, is designed to secure data directly. To further understand the design space of securing applications through securing data, we performed a case study of designing the security mechanisms for the Audio Conference Tool (ACT). Utilizing NDN's built-in primitive of signed data packets, we applied basic cryptographic schemes in a straightforward manner to effectively secure conferencing control information as well as voice data.
