Blockchain based Secure Crypto-currency system with Quantum Key Distribution Protocol

Muhammad Taimour Azhar, Muhammad Burhan Khan, Asim ur Rehman Khan

A block chain is referred to as a growing list of records which are linked using cryptography. It is simple and open ledger that records all the transactions in block structures. These block structures are bound with each other by using Quantum Cryptographic protocols. The block chain is democratic system in which concerned parties get access by using a key to perform transaction. The well-known type of Quantum Cryptography protocol is Quantum Key Distribution (QKD). With the help of QKD our Crypto-currency system is secured when passage in between transmitting end and receiving end shouldn't be intrude by third party. Secrecy of the system depends upon different factors like efficient and optimized key rate, secure carrier of modulating signal. In this work the transparency and immunity of block chain based crypto-currency system is analyzed with simulation of six state QKD Protocol. The generation of key rate is observed to ensure the path for production of better crypto-currency system. A Mathematical model is used to obtain the desire constraints so that linear relationship can be achieved. At application level this study contributes to the implementation of crypto-currency system through six state QKD protocol.

The advent of quantum computing poses a threat to the bases of classical cryptographies and thus the RSA and ECC are susceptible to attacks at the time of a poly with Shors algorithm. The present paper proposes QUBE-Crypto (Quantum Unbreakable Blockchain-Enhanced Cryptography) which is a new multi-layered protocol that facilitates a synergistic combination of Quantum Key Distribution (QKD) that can provide information-theoretic key protection, Post-Quantum Digital Signatures (Dilithium-5, SQIsignHD) that offer computational authentication resilience, blockchain-based immutable identity anchoring and Pseudorandom Quantum State (PRS) challenges that can provide unforgeable verification. Unlike existing approaches that address quantum threats in isolation, QUBE-Crypto provides end-to-end quantum-safe communication by combining provably secure key exchange, quantum-resistant signatures, decentralized trust, and clone-proof authentication. The protocol is formally specified through a five-phase algorithm encompassing initialization, QKD-based session key establishment, PRS-based challengeresponse authentication, blockchain-anchored verification, and encrypted message exchange. Applications span IoT security, smart cities, digital voting, and decentralized identity systems requiring resilience against both classical and quantum adversaries.

Internet of quantum blockchains: security modeling and dynamic resource pricing for stable digital currency

Wanyang Dai

Internet of quantum blockchains (IoB) will be the future Internet. In this paper, we make two new contributions to IoB: developing a block based quantum channel networking technology to handle its security modeling in face of the quantum supremacy and establishing IoB based FinTech platform model with dynamic pricing for stable digital currency. The interaction between our new contributions is also addressed. In doing so, we establish a generalized IoB security model by quantum channel networking in terms of both time and space quantum entanglements with quantum key distribution (QKD). Our IoB can interact with general structured things (e.g., supply chain systems) having online trading and payment capability via stable digital currency and can handle vector-valued data streams requiring synchronized services. Thus, within our designed QKD, a generalized random number generator for private and public keys is proposed by a mixed zero-sum and non-zero-sum resource-competition pricing policy. The effectiveness of this policy is justified by diffusion modeling with approximation theory and numerical implementations.
