Abstract:

This paper proposes a secure quantum repeater network coding scheme based on identity authentication by introducing quantum one-time pad into quantum repeater network.To defend against active attacks during encoding,quantum one-time pad is used for identity authentication of communication between any adjacent nodes,and coding algorithms are optimized.Eventually,quantum entanglements which are generated between source nodes and target nodes work as channels and constitute a network of quantum teleportation.Scheme analyses show that it can realize high-reliability and high-security long-distance quantum communication.

Key words: quantum network coding, quantum repeater, identity authentication, quantum one-time pad, active attacks
