Abstract
En 中文
Quantum network coding is vulnerable to pollution attacks, especially when using classical channel as auxiliary resource. On this basis, this letter proposes a secure quantum network coding scheme against pollution attacks. The scheme uses quantum homomorphic signature for the efficient authentication of different data sources so as to detect pollution attacks in the butterfly network. Furthermore, with the help of trusted intermediate nodes, it can locate a corrupt data source. Analysis results show that the proposed quantum network coding scheme can defend against pollution attacks with high fidelity, fewer resource consumption, and lower rate region.
