This paper presents a novel dynamic group multi-party Quantum Key Agreement (DGMQKA) protocol, achieved by a multicast transmission method. The proposed method is able to achieve arbitrary number of groups and members under the same resources. In addition, it can be dynamically adjusted by joining a new member, combining two groups into one group, revoking an old member and dividing one group into two groups, for different and complex situations. Furthermore, the proposed protocol can be of help to research into Quantum Secret Sharing (QSS), which it complements. The security analysis shows that the proposed protocol can resist both external and internal attacks. In consumption comparison, the proposed protocol using the multicast transmission method is more effective than other current MQKA protocols.

“…The five existing MQKA protocols are “LGHW protocol”20, “SZ protocol”21, “SZWYZL protocol”26, “SYW protocol”28, and “SZWLL protocol”29. The qubit efficiency can be defined as , where c is the length of target common key sequence, q is the number of qubits used in transmission and security checking, and “b” is the number of used classical bits.…”

“…Anther very important topic named Quantum key agreement(QKA)1617181920212223242526272829 also received widespread concerns. Compared with QKD protocols in which one participant distributes a predetermined secret key to the other participants, QKA protocols require that all participants need to negotiate mutually and equally to derive a common secret key, and any nontrivial subset of participants could not fully determine the target key.…”

Multiparty Quantum Key Agreement Based on Quantum Search Algorithm

Quantum key agreement is an important topic that the shared key must be negotiated equally by all participants, and any nontrivial subset of participants cannot fully determine the shared key. To date, the embed modes of subkey in all the previously proposed quantum key agreement protocols are based on either BB84 or entangled states. The research of the quantum key agreement protocol based on quantum search algorithms is still blank. In this paper, on the basis of investigating the properties of quantum search algorithms, we propose the first quantum key agreement protocol whose embed mode of subkey is based on a quantum search algorithm known as Grover’s algorithm. A novel example of protocols with 5 – party is presented. The efficiency analysis shows that our protocol is prior to existing MQKA protocols. Furthermore it is secure against both external attack and internal attacks.

“…Sun et al [37] presented a scheme of bidirectional quantum controlled teleportation in which a six-qubit maximally entangled state quantum channel was initially shared by the Alice, Bob, and supervisor Charlie. Sun et al [38] gave a multi-party quantum key agreement protocol utilized the state. However, to our best knowledge, up to now, there have been no protocols for how to generate DRSP of an arbitrary three-qubit state with this entangled six-qubit state as the shared quantum channel.…”

Abstract:In this paper, our concern is to design some criteria for deterministic remote state preparation for preparing an arbitrary three-particle state via a genuinely entangled six-qubit state. First, we put forward two schemes in both the real and complex Hilbert space, respectively. Using an appropriate set of eight-qubit measurement basis, the remote three-qubit preparation is completed with unit success probability. Departing from previous research, our protocol has a salient feature in that the serviceable measurement basis only contains the initial coefficients and their conjugate values. By utilizing the permutation group, it is convenient to provide the permutation relationship between coefficients. Second, our ideas and methods can also be generalized to the situation of preparing an arbitrary N-particle state in complex case by taking advantage of Bell states as quantum resources. More importantly, criteria satisfied conditions for preparation with 100% success probability in complex Hilbert space is summarized. Third, the classical communication costs of our scheme are calculated to determine the classical recourses required. It is also worth mentioning that our protocol has higher efficiency and lower resource costs compared with the other papers.
