Secure Quantum Secret Sharing Based on Reusable GHZ States as Secure Carriers

Abstract

We show that a potential eavesdropper can eavesdrop whole secret information when the legitimate users use secure carrier to encode and decode classical information repeatedly in the protocol proposed by Bagherinezhad S and Karimipour V [Phys. Rev. A 67 (2003) 044302]. Then we present a revised quantum secret sharing protocol by using the Greenberger–Horne–Zeilinger state as secure carrier. Our protocol can resist Eve's attack.

In a recent paper [S. Bagherinezhad and V. Karimipour, Phys. Rev. A 67, 044302 (2003)], a quantum secret sharing protocol based on reusable Greenberger-Horne-Zeilinger states was proposed. However, in this Comment, it is shown that this protocol is insecure if Eve employs a special strategy to attack.

Inspired by the protocol presented by Bagherinezhad and Karimipour [ Phys. Rev. A 67 (2003) 044302 ], which will be shown to be insecure, we present a multipartite quantum secret sharing protocol using reusable Greenberger—Horne—Zeilinger (GHZ) states. This protocol is robust against eavesdropping and could be used for the circumstance of many parties.

In a recent paper [S. Bagherinezhad and V. Karimipour, Phys. Rev. A 67, 044302 (2003)], a quantum secret sharing protocol based on reusable GHZ states was proposed. However, in this comment, it is shown that this protocol is insecure because a cheater can gain all the secret bits before sharing, while introducing one data bit error at most in the whole communication, which makes the cheater avoid the detection by the communication parities.

Quantum secret sharing based on reusable Greenberger-Horne-Zeilinger states as secure carriers

Saber Bagherinezhad, Vahid Karimipour

We introduce a protocol for quantum secret sharing based on reusable entangled states. The entangled state between the sender and the receiver acts only as a carrier to which data bits are entangled by the sender and disentangled from it by the receivers, all by local actions of simple gates. We also show that the interception by Eve or the cheating of one of the receivers introduces a quantum bit error rate larger than 25% which can be detected by comparing a subsequence of the bits.

We show that the criticism of a recent Comment by Gao et al. on the insecurity of the quantum secret sharing protocol [proposed in S. Bagherinezhad and V. Karimipour, Phys. Rev. A 67, 044302 (2003)] is based on a misconception about the meaning of security and hence is invalid.
