Practical quantum multiparty signatures using quantum key distribution networks

  title={Practical quantum multiparty signatures using quantum key distribution networks},
  author={Evgeniy O. Kiktenko and A. S. Zelenetsky and Aleksey K. Fedorov},
Digital signatures are widely used for providing security of communications. At the same time, the security of currently deployed digital signature protocols is based on unproven computational assumptions. An efficient way to ensure an unconditional (information-theoretic) security of communication is to use quantum key distribution (QKD), whose security is based on laws of quantum mechanics. In this work, we develop an unconditionally secure signatures (USS) scheme that guarantees authenticity… Expand

Unconditionally Secure Quantum Signatures
This paper aims to provide an accessible and comprehensive review of existing unconditionally secure secure signature schemes for signing classical messages, with a focus on unconditional or information-theoretic security quantum signature schemes. Expand
Lightweight Authentication for Quantum Key Distribution
A lightweight authentication protocol for QKD based on a ‘ping-pong’ scheme of authenticity check based on the combination of almost universal2 polynomial hashing, XOR universal2 Toeplitz hashing, and one-time pad (OTP) encryption is developed. Expand
Experimental measurement-device-independent quantum digital signatures
A reconfigurable quantum network where the central node can switch between trusted and untrusted operation, and devised an efficient protocol to distil multiple signatures from the same block of data, thus reducing the statistical fluctuations in the sample and greatly enhancing the final QDS rate in the finite-size scenario.

Unconditionally Secure Digital Signature Schemes Admitting Transferability
This work establishes a model for unconditionally secure digital signatures in a group, and demonstrates practical schemes in that model that represents the first unconditionallySecure signature that admits provably secure transfer of signatures. Expand
Experimental demonstration of quantum digital signatures using phase-encoded coherent states of light
