A general scheme for information interception in the ping pong protocol
The existence of an undetectable eavesdropping of dense coded information has been already demonstrated by Pavičić for the quantum direct communication based on the ping-pong paradigm. However, a) the explicit scheme of the circuit is only given and no design rules are provided, b) the existence of losses is implicitly assumed, c) the attack has been formulated against qubit based protocol only...
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...
متن کاملImproving the capacity of the ping-pong protocol
Since Bennett and Brassard presented the pioneer quantum key distribution (QKD) protocol in 1984 [1], there are a lot of theoretical QKD schemes [1-12] today. Recently, Beige et al. proposed a quantum secure direct communication scheme [13], which allows messages communicated directly without first establishing a random key to encrypt them. Bostroem and Felbingeer presented a ping-pong protocol...
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 کاملPing pong in the pore
Getting to the inner circle ontiguity between the ER and the nuclear envelope means nuclear membrane proteins have a direct shot to their target. In fact, inner nuclear membrane (INM) proteins were thought to need only to diffuse to the nucleus, pass through the nuclear pore, and then be retained by nuclear-localized binding partners. But new results suggest a more active process. Suraj Saksena...
