Abstract

We present a scheme for teleporting an unknown, two-particle entangled state with a message from a sender (Alice) to a receiver (Bob) via a six-particle entangled channel. We also present another scheme for teleporting an unknown one-particle entangled state with a message transmitted in a two-way form between the same sender and receiver via a five-qubit cluster state. One-way hash functions, Bell-state measurements, and unitary operations are adopted in these two schemes. Our schemes use the physical characteristics of quantum mechanics to implement delegation, signature, and verification processes. Moreover, a quantum key distribution protocol and a one-time pad are adopted in these schemes.

A quantum proxy group signature scheme based on an entangled five-qubit state

A quantum proxy group signature (QPGS) scheme based on controlled teleportation is presented, by using the entangled five-qubit quantum state functions as quantum channel. The scheme uses the physical characteristics of quantum mechanics to implement delegation, signature and verification. The security of the scheme is guaranteed by the entanglement correlations of the entangled five-qubit state, the secret keys based on the quantum key distribution (QKD) and the one-time pad algorithm, all of which have been proven to be unconditionally secure and the signature anonymity.

Quantum Safe Proxy Blind Signature Protocol Based on 3D Entangled GHZ‐Type States

ABSTRACT As quantum technology advances, classical digital signatures exhibit vulnerabilities in preserving security properties during the transmission of information. Working toward a reliable communication protocol, we introduce a proxy blind signature scheme to teleport a single particle qubit state with a message to the receiver, employing a three qubit GHZ entangled state. The blindness property is utilized to secure the message information from the proxy signer. A trusted party, Trent, is introduced to supervise the communication process. Alice blinds the original message and sends the Bell measurements with her entangled particle to proxy signer Charlie. After receiving measurements from Alice and Charlie, Bob verifies the proxy blind signature and performs appropriate unitary operations on his particle. Thereafter, Trent verifies the security of the quantum teleportation setup by matching the output data with the original data sent by Alice. Security analysis results prove that the proposed scheme fulfils the basic security necessities, including undeniability, unforgeability, blindness, verifiability, and traceability.

Controlled quantum teleportation and secure direct communication

Gao Ting, Yan Feng-Li, Wang Zhi-Xi

We present a controlled quantum teleportation protocol. In the protocol, quantum information of an unknown state of a 2-level particle is faithfully transmitted from a sender Alice to a remote receiver Bob via an initially shared triplet of entangled particles under the control of the supervisor Charlie. The distributed entangled particles shared by Alice, Bob and Charlie function as a quantum information channel for faithful transmission. We also propose a controlled and secure direct communication scheme by means of this teleportation. After ensuring the security of the quantum channel, Alice encodes the secret message directly on a sequence of particle states and transmits them to Bob supervised by Charlie using this controlled quantum teleportation. Bob can read out the encoded message directly by the measurement on his qubit. In this scheme, the controlled quantum teleportation transmits Alice's message without revealing any information to a potential eavesdropper. Because there is not a transmission of the qubit carrying the secret message between Alice and Bob in the public channel, it is completely secure for controlled and direct secret communication if perfect quantum channel is used. The special feature of this scheme is that the communication between two sides depends on the agreement of a third side to co-operate.

A proxy blind signature protocol based on quantum teleportation

Yulu Wang, Dianjun Lu, Sihui Ma

With the advancement of quantum cryptography, proxy blind signature technology combines the message concealment of blind signatures with the delegation of authority inherent in proxy signatures, thereby simultaneously ensuring message privacy and the controlled delegation of signing authority, and playing a critical role in numerous fields. This paper proposes a quantum proxy blind signature protocol based on quantum teleportation. This protocol has the following features: First, by simplifying the keys and the encryption process and using a pseudorandom number generator and quantum state permutations to perform encryption, we avoid complex unitary transformations, thereby significantly lowering the technical barrier. Second, by employing high-capacity quantum encoding — where a two-particle quantum state encodes three classical bits — the information capacity of a single communication session is significantly increased. Finally, we propose the “local operation, global signature” paradigm, in which the surrogate need only manipulate a single entangled particle to achieve a global signature through nonlocality, while the verifier recovers the message via a joint measurement. This approach conserves quantum resources and simplifies the verification process. The security analysis demonstrates that the proposed protocol can ensure blindness, satisfy the requirements of unforgeability and undeniability, and effectively resistance to interception-retransmission attacks.

A general scheme for controlled teleportation of an unknown two-qubit entangled state with four-qubit cluster state is proposed.The sender performs a measurement by three particles entangled basis on her own three qubits and the controller needs also take a local measurement.The receiver can reconstruct the unknown state teleported by the sender by performing appropriate unitary operations on his particles if he cooperates with the controller,then the controlled teleportation is accomplished.
