Universal classical-quantum superposition coding and universal classical-quantum multiple access channel coding
Masahito Hayashi, Ning Cai
We derive universal classical-quantum superposition coding and universal classical-quantum multiple access channel code by using generalized packing lemmas for the type method. Usi…
Asymptotically Secure Network Code for Active Attacks and its Application to Network Quantum Key Distribution
Masahito Hayashi, Ning Cai
When there exists a malicious attacker in the network, we need to be careful of eavesdropping and contamination. This problem is crucial for network communication when the network…
Secure network code over one-hop relay network
Masahito Hayashi, Ning Cai
When there exists a malicious attacker in the network, we need to consider the possibilities of eavesdropping and the contamination simultaneously. Under an acyclic broadcast netwo…
Reduction Theorem for Secrecy over Linear Network Code for Active Attacks
Masahito Hayashi, Masaki Owari, Go Kato +1
We discuss the effect of sequential error injection on information leakage under a network code. We formulate a network code for the single transmission setting and the multiple tr…
