Journal ArticleDOI
Cryptanalysis of the Hillery-Bužek-Berthiaume quantum secret-sharing protocol
TL;DR: A method is presented to analyze the security of quantum secret-sharing protocols against this kind of attack taking the scheme of Hillery, Buzek, and Berthiaume (HBB) as an example, and shows that the HBB protocol is insecure against dishonest participants.
Journal ArticleDOI
A simple participant attack on the brádler-dušek protocol
TL;DR: By a special strategy, Bob can steal Charlie's portion of information without being detected and then recover Alice's secret by himself and point out a possible way to improve the protocol to stand against this attack.
Journal ArticleDOI
Cryptanalysis of multiparty controlled quantum secure direct communication using Greenberger-Horne-Zeilinger state
TL;DR: It is shown that the receiver, using a special property of GHZ state, can illegally obtain 33.3% of the sender's secret without any controller’s permission.
Journal ArticleDOI
Cryptanalysis of the arbitrated quantum signature protocols
TL;DR: This paper shows that in previous AQS protocols the receiver, Bob, can realize existential forgery of the sender's signature under known message attack, and the sender, Alice, can successfully disavow any of her signatures by simple attack.
Journal ArticleDOI
Novel multiparty quantum key agreement protocol with GHZ states
TL;DR: This paper proposes a novel three-party QKA protocol, which is designed by using Greenberger–Horne–Zeilinger (GHZ) states, and shows that the new scheme is secure and fair to every participant.
