Abstract

In a recent paper [A. Cabello, Phys. Rev. A 61, 052312 (2000)], a quantum key distribution protocol based on entanglement swapping was proposed. However, in this Comment, it is shown that this protocol is insecure if Eve uses a special strategy to attack.

Recently, Zhang, Li, and Guo have proposed a particular eavesdropping attack [Phys. Rev. A {\bf 63}, 036301 (2001), quant-ph/0009042] which shows that my quantum key distribution protocol based on entanglement swapping [Phys. Rev. A {\bf 61}, 052312 (2000), quant-ph/9911025] is insecure. However, security against this attack can be attained with a simple modification. In addition, a simpler version of the protocol using four qubits is introduced.

A Modified Protocol of Quantum Key Distribution Based on Entanglement Swapping

Xin Huang, Li Shu-Min, Wang An-Min

By comparing Cabello's addendum to his quantum key distribution protocol [Phys. Rev. A 64 (2001) 024301], we propose a more convenient modified protocol based on the entanglement swapping which is secure against the eavesdropping strategy addressed by Zhang et al. [Phys. Rev. A 63 (2001) 036301] and other existing types of attack.

Comment on "Quantum key distribution via quantum encryption"

Fei Gao, Su‐Juan Qin, Qiaoyan Wen +1 more

In the paper [Zhang, Li and Guo, Phys. Rev. A 64, 024302 (2001)], a quantum key distribution protocol based on quantum encryption was proposed, in which the quantum key can be reused. However, it is shown that, if Eve employs a special strategy to attack, this protocol becomes insecure because of the reused quantum key. That is, Eve can elicit partial information about the key bits without being detected. Finally, a possible improvement of the Zhang-Li-Guo protocol is proposed.

Comment on “Multiparty quantum secret sharing of classical messages based on entanglement swapping”

Song Lin, Fei Gao, Fen-Zhuo Guo +2 more

In a recent paper [Z. J. Zhang and Z. X. Man, Phys. Rev. A 72, 022303 (2005)], a multiparty quantum secret sharing protocol based on entanglement swapping was presented. However, as we show, this protocol is insecure in the sense that an unauthorized agent group can recover the secret from the dealer. Hence we propose an improved version of this protocol which can stand against this kind of attack.
