In this presentation, I discuss my recent project that aims to make time-series data better encrypted. Currently, encryption among several clients relies on static keys. This is far from ideal, as it means that compromised keys can result in the entire communication chain becoming compromised. Using polynomials, we can efficiently update shared keys among large networks. Applications for this include:

  • VoIP and Teleconferencing
  • DRM for IPTV
  • Secure Radio Broadcasts
  • Group Messaging
