Secrecy and robustness for active attack in secure network coding
Masahito Hayashi, Masaki Owari, Go Kato, Ning Cai · 2017
In the network coding, we discuss the effect by sequential error injection to information leakage. We show that there is no improvement when the network is composed of linear operations. However, when the network contains non-linear operations, we find a counterexample to improve Eve's obtained information. Further, we discuss the asymptotic rate in the linear network under the secrecy and robustness conditions.
