Photon Number Coherence in Quantum Dot‐Cavity Systems can be Enhanced by Phonons

Advanced Quantum Technologies, Volume 8, Issue 7, July 2025.
Photon number coherence (PNC) is important for quantum cryptography. Because of that, the PNC within a quantum dot‐cavity system is investigated theoretically. Phonons, which interact with the quantum dot, surprisingly do not necessarily decrease PNC. It is demonstrated that it is possible to optimize other figures of merit without significant penalty ...

On the security of joint signature and encryption revisited

Journal of Mathematical Cryptology, 2016
In 2002, An et al. [1] proposed three generic conversions of signcryption, ℰ⁢t⁢𝒮${\mathcal{E}t\mathcal{S}}$, 𝒮⁢t⁢ℰ${\mathcal{S}t\mathcal{E}}$ and 𝒞⁢t⁢ℰ&𝒮${\mathcal{C}t\mathcal{E}\&\mathcal{S}}$ from the primitive encryption scheme and signature scheme ...

Generic Transformation to Strongly Unforgeable Signatures [PDF]

, 2007
Recently, there are several generic transformation techniques proposed for converting unforgeable signature schemes (the message in the forgery has not been signed yet) into strongly unforgeable ones (the message in the forgery could have been signed previously). Most of the techniques are based on trapdoor hash functions and all of them require adding

MSC: A Unique Chameleon Hash‐Based Off‐Chain Storage Framework for Metaverse Applications

International Journal of Network Management, Volume 35, Issue 1, January/February 2025.
This paper presents the Metaverse Off‐chain Storage Framework based on Chameleon hash (MSC), a unique framework for decentralized systems that supports code or stored data updates without changing on‐chain data. It significantly reduces overhead compared to directly storing data within a smart contract. ABSTRACT Blockchain has evolved into a secure and
