IEEE Access, 2022 This paper proposes a novel lattice-based aggregate signature (LAS) scheme that brings post-quantum security to the Bitcoin system without sacrificing its transaction efficiency. Bitcoin currently employs Elliptic Curve Digital Signature Algorithm (ECDSA)

Quantum signatures from Hoava–Lifshitz cosmography [PDF]
Classical and Quantum Gravity, 2021 Abstract In this paper we propose an alternative cosmography by considering Hořava–Lifshitz gravity as a model of quantum gravity (QG) to search for quantum effects at the cosmological level. For our analyses we consider current late Universe surveys and a gravitational waves forecast from Einstein telescope.

Secure quantum signatures using insecure quantum channels [PDF]
Physical Review A, 2016 Digital signatures are widely used in modern communication to guarantee authenticity and transferability of messages, The security of currently used classical schemes relies on computational assumptions. We present a quantum signature scheme that does not require trusted quantum channels.

Cryptanalysis of a Semi-Quantum Bi-Signature Scheme Based on W States
Entropy, 2022 Recently, Zhao et al. proposed a semi-quantum bi-signature (SQBS) scheme based on W states with two quantum signers and just one classical verifier. In this study, we highlight three security issues with Zhao et al.’s SQBS scheme.

Quantum messages with signatures forgeable in arbitrated quantum signature schemes [PDF]
Physica Scripta, 2015 Even though a method to perfectly sign quantum messages has not been known, the arbitrated quantum signature scheme has been considered as one of good candidates. However, its forgery problem has been an obstacle to the scheme being a successful method. In this paper, we consider one situation, which is slightly different from the forgery problem, that

Forward Secure Sequential Aggregate Signature Schemes on Lattice
Jisuanji kexue yu tansuo, 2021 The forward secure sequential aggregate (Fss-Agg) signature has the advantages of forward secure signature and the sequential aggregate signature at the same time. Since its proposal in 2007, it has been widely applied in many application scenarios, such

A New Quantum Blind Signature Scheme with BB84-State
Entropy, 2019 The blind signature is widely used in cryptography applications because it can prevent the signer from gaining the original message. Owing to the unconditional security, the quantum blind signature is more advantageous than the classical one.
