With the continuous development of quantum technology, the quantum signature as an application of quantum cryptography has received great attention. In this paper, we propose a public-key quantum group blind signature scheme based on single-qubit rotations. In this scheme, the group manager generates a public key. Each group member randomly generates his own private key according to the public key. The signer uses his private key and random sequence to generate the signature. The verifier uses the public key to verify the correctness of the quantum signature. The public and private keys can be reused, which simplifies the key management of the signature system. In this scheme, the random sequence is used to enhance the security of the scheme. At the same time, the quantum efficiency is improved by using single-qubit rotations. The security analysis shows that our scheme can ensure the security of the keys, the unforgeability and the non-deniability of the signature.

“…At the same time, in the signing phase, the signer Bob − i uses random classical string to ensure the security of the signature. Compared with schemes [20,44,45], the proposed scheme applies the single-qubit rotations to improve the quantum efficiency. All algorithms in this scheme are public, which follows the Kerckhoffs's principle.…”

“…Digital signatures are widely used to ensure the identity of a signer, the authenticity of a message, and to guarantee that a message is transferable. To react to the threat of quantum computers, unconditionally secure signature (USS) schemes have been proposed in recent years [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. The new USS scheme proposed recently by Amiri et al [ 23 ] has been proven to exhibit many advantages over the other existing USS schemes.…”

While Blockchain technology is universally considered as a significant technology for the near future, some of its pillars are under a threat of another thriving technology, Quantum Computing. In this paper, we propose important safeguard measures against this threat by developing a framework of a quantum-secured, permissioned blockchain called Logicontract (LC). LC adopts a digital signature scheme based on Quantum Key Distribution (QKD) mechanisms and a vote-based consensus algorithm to achieve consensus on the blockchain. The main contribution of this paper is in the development of: (1) unconditionally secure signature scheme for LC which makes it immune to the attack of quantum computers; (2) scalable consensus protocol used by LC; (3) logic-based scripting language for the creation of smart contracts on LC; (4) quantum-resistant lottery protocol which illustrates the power and usage of LC.

A Novel Quantum Sequential Signature Protocol With Y-SNOP States

With the development of quantum technology, an arising researching point is to solve some new cipher problems with quantum technology to ensure their security. As we know, the sequential signature means to sign a contract or a document by many signers one by one. It has been widely used to realize layered authentication. In this paper, we propose a quantum sequential signature protocol with a set of strongly nonlocal orthogonal product (Y-SNOP) states. It is proved that the present protocol is secure, i.e., anyone cannot deny or forge a valid signature even some of them conspire. Compared with the existing quantum multi signature with some nonlocal orthogonal product (NOP) states, the present protocol seems more efficient and easier to be realized in Noisy Intermediate-Scale Quantum (NISQ) device as no entangled resources are required.INDEX TERMS Quantum sequential signature, strongly nonlocal orthogonal product, collusion attack.
