Security of modified Ping-Pong protocol in noisy and lossy channel
The "Ping-Pong" (PP) protocol is a two-way quantum key protocol based on entanglement. In this protocol, Bob prepares one maximally entangled pair of qubits, and sends one qubit to Alice. Then, Alice performs some necessary operations on this qubit and sends it back to Bob. Although this protocol was proposed in 2002, its security in the noisy and lossy channel has not been proven. In this repo...
متن کاملOn the Security of Quantum Key Distribution Ping-Pong Protocol
Computational based cryptography might not guarantee long term security if computational algorithms, computers, and so on are made remarkable progress. Therefore, quantum cryptography with unconditionally security attracts attention. In this paper, we consider security of a two-way quantum key distribution protocol, so called Ping-Pong protocol. As a result, we introduce not only robustness but...
متن کاملOn the Security of the Ping-Pong Protocol
We briefly review the security of the ping-pong protocol in light of several attack scenarios suggested by various authors since the proposal of the protocol. We refute one recent attack on an ideal quantum channel, and show that a recent claim of falseness of our original security proof is erroneous.
متن کاملOn the Security of Ping-Pong Protocols
Consider the class of protocols, for two participants, in which the initiator applies a sequence of operators to a message M and sends it to the other participant ; in each step, one of the participants applies a sequence of operators to the message received last, and sends it back . This "ping-pong" action continues several times, using sequences of operators as specified by the protocol . The...
متن کاملAttack the ‘ping-pong’ protocol without eavesdropping
Qing-yu Cai Wuhan Institute of Physics and Mathematics, The Chinese Academy of Sciences, Wuhan, 430071, People’s Republic of China Bostr .. om and Felbinger [1] have presented a ping-pong communication protocol which allows the information transferred in a deterministic secure manner. The security of this ping-pong protocol is based on an entangled pair of qubits. And the proof of the case of e...
