Abstract

Abstract With the development of information society, network security problems are becoming more and more serious, and digital signature as an authentication method is widely used in many fields such as information security and e-commerce, mainly to solve security problems such as forgery, repudiation, impersonation and tampering [1]. The latest quantum technology can overcome a series of difficult problems of classical digital signatures in a very short time. In this paper, we propose a quantum multiproxy blind signature scheme, in which the original signer is unable to sign the document himself, and delegates multiple proxy signers to sign and verify the document, and the signature order of the proxy signers is not restricted. The scheme adopts techniques such as Unitary transformation and Hadamard gate, and uses quantum key distribution protocol to ensure its security, which improves the efficiency of signature, ensures the security of signature, and has certain anti-attack capability.

A Quantum Multi-agent Blind Signature Scheme

Jingjing Chen, Fucheng You

Abstract With the development of information society, people are increasingly concerned about the security problems caused by information leakage, and digital signatures play an irreplaceable and important role in the protection of information security, which replace traditional manual signatures and seals in the network environment and have important roles such as anti-forgery, anti-tampering, anti-replay, identifiable identity and confidentiality [1]. However, with the in-depth study of quantum mechanics, it has been found that the confidentiality mechanism of classical digital signatures is under serious threat. Since quantum computing is a parallel operation with exponentially increasing operational capability, a series of complex mathematically difficult problems can be rapidly overcome. Based on the above, this paper proposes a multiple agent blind signature scheme, which adopts the key technologies such as the Unitary transformation and Hadamard gate operation, and adds multiple agent signature to quantum signature to improve the efficiency of the protocol, and adds blind signature to improve the security of the protocol. At the same time, the scheme uses quantum key distribution to ensure its unconditional security, which is applicable in systems such as electronic voting and electronic payment, and has certain anti-attack capability [2].

A multi-party verifiable quantum proxy blind signature scheme based on controlled quantum teleportation

Chengxiang Wang, Dianjun Lu, Fuyao Tian +1 more

Abstract When the original signer is unable to sign and the proxy signer does not know the information content, proxy blind signature comes into being and becomes a hot topic in cryptography research. This paper combines the methods of proxy blind signature, controlled quantum teleportation and multi-party verification, and proposes a multi-party verifiable quantum proxy blind signature scheme based on controlled quantum teleportation. This scheme has the following features: using a Hash function shared by all participants for authentication can effectively solve the problem of identity identification among members; in order to facilitate the original signer to ensure the security of proxy authorization, the quantum proxy signature authorization form is used to generate quantum states with mutual unbiased fundamental particles. The security analysis shows that the scheme is unforgeable and undeniable, and can resist intercept-forgery attack and collusive attack.

A multi-party verifiable quantum proxy signature scheme based on quantum teleportation

Chengxiang Wang, Dianjun Lu, Fuyao Tian +1 more

With the development of science and technology and the appearance of various special conditions that cause signers to be unable to sign, proxy signature is gradually becoming a hot spot in cryptography research. This paper combines proxy signature, quantum teleportation, and multi-party verification and proposes a multi-party verifiable quantum proxy signature scheme based on quantum teleportation. This scheme has the following characteristics: The authentication method based on the Hash function can effectively solve the problem of identity identification among members; in order for the proxy signer to be able to verify the correctness of the proxy authorization, a form of proxy signature authorization that concatenates the identity information of the original signer is used. The security analysis shows that our scheme is unforgeable and undeniable and can resist intercept-resend attacks and cheating attacks.

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.

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.

Semiquantum group proxy blind signature

Xiao TAN, ZhiGang GAN, TianYu YE

In this study, we propose the semiquantum group proxy blind signature scheme, in which the signature verifier and some proxy signers only possess limited quantum capabilities. On the basis that the original message content of the original message owner is blind to the original signer, the signature verifier, the proxy signature group and the trusted third party helping complete the signing process, this scheme can accomplish the goal of the original singer authorizing the proxy signature group to sign this original message. This scheme is proved to have unforgeability, non-repudiation, complete blindness and security. Since the signature verifier and some proxy signers only possess limited quantum capabilities, compared with many existing quantum group proxy blind signature protocols, this scheme has a wider range of signature application scenarios.
