CONTINUOUS VARIABLE QUANTUM SIGNATURE ALGORITHM

International Journal of Quantum Information, 2007
A true quantum signature algorithm based on continuous-variable entanglement state is proposed. In the suggested algorithm, a key-pair, i.e. private signature key and public verification key, is generated based on a one-way function. By employing the signature key, a message state is encoded into a 2k-particle entangled state and a two-particle ...

Efficient identity-based public-key quantum signature scheme

, 2020
Based on the Hadamard operator and Bell states, an identity-based public-key quantum signature scheme is proposed. In our scheme, the signer’s identity is used as her public key.

Public Blockchain-Envisioned Security Scheme Using Post Quantum Lattice-Based Aggregate Signature for Internet of Drones Applications

IEEE Transactions on Vehicular Technology, 2023
Due to high effectiveness and robust security protocols, lattice-based cryptography becomes a very broadly applicable optimistic post-quantum technique that is recently used in public key cryptosystem.

Efficient arbitrated quantum signature scheme without entangled states

Modern Physics Letters A, 2019
In the most arbitrated quantum signatures (AQSs), the signers and verifiers need to perform the quantum key distribution protocols or some other protocols to share secret keys before signing a signature.

Quantum signatures for screening metavalent solids

The Journal of Chemical Physics, 2021
The objective of this paper is to describe a new data-driven framework for computational screening and discovery of a class of materials termed “metavalent” solids. “Metavalent” solids possess characteristics that are nominally associated with metallic and covalent bonding (in terms of conductivity and coordination numbers) but are distinctly different

Post-Quantum Signature Schemes for Efficient Hardware Implementation

International Conference on New Technologies, Mobility and Security, 2019
Post-quantum cryptosystems have attracted a great interest, from researchers, latest. This work introduces a new form of the hidden discrete logarithm problem and two new post-quantum signature schemes.

Quantum signature scheme based on Hadamard and Hπ/4 operators.

Applied Optics, 2019
Based on the Hadamard and Hπ/4 operators, a new quantum signature scheme is proposed. In our scheme, the signer's private key is generated by a trusted private key generator (PKG), while the identity information of the signer is used as the corresponding
