Abstract

A proxy blind signature protocol using quantum entanglement state for signature and verification was proposed, while nonorthogonal quantum state encoded proxy warrant message. The quantum key distribution and one-time pad encryption algorithm guaranteed the unconditional security and the message owner's anonymity.

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 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.

Arbitrated Proxy Signature Scheme Based on Quantum Cryptography

Xiuqing Wang, Jun Zhang

Proxy signature is a special signature which provided the signer can delegate his signing capability to others.The proxy signature provides that the original signer can delegate his signing permission to a proxy signer, and the proxy signer can replace the original signer to sign the message.In this paper, we propose a proxy signature scheme based on ideas from classical proxy signature schemes and quantum cryptography.The scheme is implemented by Bell states and a symmetrical quantum key cryptosystem.Compile with classical proxy signature schemes, the new scheme can guarantee the security by using quantum key distribution and one-time pads.And it also can prove that the scheme have the characteristics of non-counterfeit, non-disavowal and traceability.Furthermore, the new scheme uses a special quantum encryption to ensure the receiver cannot forge the signature.The validity of the new scheme can be verified, and it is a secure proxy signature scheme.

A quantum partially blind signature scheme without entanglement

Juxiu Zhong, Bolin Liao, Yuanquan Shi +1 more

In a quantum partially blind signature (QPBS) scheme, the contradiction between anonymity and controllability of completely blind signature (BS) schemes was better solved by adding common negotiated public information between the signer and the requester (the message holder). After reviewing the proposed scheme, we give an analysis about it and then propose a novel QPBS scheme without entanglement. The security without preconditions of this signature scheme is ensured by the secure quantum key distribution (QKD) protocol and quantum one-time pad (QOTP). Furthermore, in the process of security analysis, it proves that our scheme satisfies the foundational attribution of partially blind signature (PBS). Moreover, the scheme can solve the problem we put forward so as to allow it to have a wider application in the future.
