Secure network coding with erasures and feedback. Czap, L., Fragouli, C., Prabhakaran, V., & Diggavi, S. In Communication, Control, and Computing (Allerton), 2013 51st Annual Allerton Conference on, pages 1517-1524, Oct, 2013. doi abstract bibtex Secure network coding assumes that the underlying network links are lossless, thus it can be applied over lossy networks after channel error correction. Yet it is well known that channel losses, such as packet erasures, can be constructively used for secrecy over a link. We address here the challenge of extending these results for arbitrary networks. We provide achievability schemes over erasure networks with feedback, that outperform the alternative approach of channel error correction followed by secure message transmission separation. We derive outer bounds on the securely achievable rate and as a consequence we show optimality of our proposed scheme in some special cases.
