On combining information-theoretic and cryptographic approaches to network coding security against the pollution attack
Svitlana Vyetrenko, Aditya Khosla, Tracey Ho · 2009
In this paper we consider the pollution attack in network coded systems where network nodes are computationally limited. We consider the combined use of cryptographic signature based security and information theoretic network error correction and propose a fountain-like network error correction code construction suitable for this purpose.
