Abstract: Currently used digital signatures based on asymmetric cryptography will be vulnerable to quantum computers running Shor's algorithm. In this work, we propose a new quantum-assisted digital signature protocol based on symmetric keys generated by QKD, that allows signing and verifying messages in a simple way implementing an integration of currently available classical and quantum technologies. The protocol is described for a three-user scenario composed of one sender and two receivers. In contrast to previous schemes, it is independent of the message length. The security of the protocol has been analyzed, as well as its integrity, authenticity and non-repudiation properties.

Towards efficient and secure quantum-classical communication networks [47.27205216718476]
There are two primary approaches to achieving quantum-resistant security: quantum key distribution (QKD) and post-quantum cryptography (PQC) We introduce the pros and cons of these protocols and explore how they can be combined to achieve a higher level of security and/or improved performance in key distribution. We hope our discussion inspires further research into the design of hybrid cryptographic protocols for quantum-classical communication networks.

Efficient Arbitrated Quantum Digital Signature with Multi-Receiver Verification [3.6788660756664773]
Quantum digital signature is used to authenticate the identity of the signer with theoretical security. In traditional multi-receiver quantum digital signature schemes without an arbitrater, the transferability of one-to-one signature is always required to achieve unforgeability. We propose an arbitrated quantum digital signature scheme, in which the signature can be verified by multiple receivers simultaneously.

Revocable Quantum Digital Signatures [57.25067425963082]
We define and construct digital signatures with revocable signing keys from the LWE assumption. In this primitive, the signing key is a quantum state which enables a user to sign many messages. Once the key is successfully revoked, we require that the initial recipient of the key loses the ability to sign.

Efficient Quantum Digital Signatures without Symmetrization Step [7.848038078036641]
Quantum digital signatures (QDS) exploit quantum laws to guarantee non-repudiation, unforgeability and transferability of messages. Current QDS protocols face two major restrictions, including the requirement of the symmetrization step. We present an efficient QDS protocol to overcome these issues by utilizing the classical post-processing operation called post-matching method.
