Enhanced quantum signature scheme using quantum amplitude amplification operators. [PDF]
PLoS One, 2021 Quantum signature is the use of the principles of quantum computing to establish a trusted communication between two parties. In this paper, a quantum signature scheme using amplitude amplification techniques will be proposed.

A Quantum Dual-Signature Protocol Based on SNOP States without Trusted Participant
Entropy, 2021 Quantum dual-signature means that two signed quantum messages are combined and expected to be sent to two different recipients. A quantum signature requires the cooperation of two verifiers to complete the whole verification process.

A Quantum Proxy Signature Scheme Without Restrictions on the Identity and Number of Verifiers. [PDF]
Entropy (Basel)Quantum digital signatures (QDS) establish a framework for information-theoretically secure authentication in quantum networks. As a specialized extension of QDS, quantum proxy signatures facilitate secure delegation of signing privileges in distributed ...

Multiparty quantum signature schemes [PDF]
Quantum Information and Computation, 2016 Digital signatures are widely used in electronic communications to secure important tasks such as financial transactions, software updates, and legal contracts. The signature schemes that are in use today are based on public-key cryptography and derive their security from computational assumptions.

Quantum signatures in the quantum Carnot cycle
New Journal of Physics, 2020 The Carnot cycle combines reversible isothermal and adiabatic strokes to obtain optimal efficiency, at the expense of a vanishing power output. Quantum Carnot-analog cycles are constructed and solved, operating irreversibly with positive power.

Logarithmic-Size Post-Quantum Linkable Ring Signatures Based on Aggregation Operations. [PDF]
Entropy (Basel)Linkable ring signatures are a type of ring signature scheme that can protect the anonymity of signers while allowing the public to verify whether the same signer has signed the same message multiple times.

Digital Signatures with Quantum Candies [PDF]
Entropy, 2022 Quantum candies (qandies) represent a type of pedagogical simple model that describes many concepts from quantum information processing (QIP) intuitively without the need to understand or make use of superpositions and without the need of using complex algebra. One of the topics in quantum cryptography that has gained research attention in recent years

Two Quantum Proxy Blind Signature Schemes Based on Controlled Quantum Teleportation
Entropy, 2022 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.
