Blockchain Security in the Post-Quantum Era

Iraq Ahmad Reshi

The quantum computer is a threat to the cryptography on which the currently implemented blockchains rely. Authors thoroughly investigate the impact of quantum adversaries on the security of blockchain technology in this chapter. Begining by scrutinizing the threat model for a quantum computer, concentrating on the threat posed by quantum adversaries on public key cryptography, digital signatures, and proof-of-work assumptions. This chapter examines various forms of cryptography after quantum computing, such as lattice-based cryptography, hash-based signatures, code-based cryptography, multivariate cryptography, and isogeny-based cryptography, highlighting their applications for blockchain technology. Authors also investigate how quantum computer cryptography can be applied in digital wallets, transactions, consensus algorithms, and smart contracts. Finally, this chapter provides case studies on real-life applications for a quantum compute-r resilient blockchain technology implementation.

Generic Quantum Blockchain-Envisioned Security Framework for IoT Environment: Architecture, Security Benefits and Future Research

Mohammad Wazid, Ashok Kumar Das, Youngho Park

Quantum cryptography has the potential to secure the infrastructures that are vulnerable to various attacks, like classical attacks, including quantum-related attacks. Therefore, quantum cryptography seems to be a promising technology for the future secure online infrastructures and applications, like blockchain-based frameworks. In this paper, we propose a generic quantum blockchain-envisioned security framework for an Internet of Things (IoT) environment. We then discuss some potential applications of the proposed framework. We also highlight the security advantages of quantum cryptography-based systems. We explain the working of blockchain, applications of blockchain, types of blockchain, the structure of blockchain, the structure of blockchain in a classical blockchain, and the structure of a block in a quantum blockchain context. Next, the adverse effects of quantum computing on the security of blockchain-based frameworks are highlighted. Furthermore, the comparisons of quantum cryptography-based security schemes, like quantum key distribution, quantum digital signature, and quantum hashing schemes, are provided. Finally, some future research directions related to the designed generic quantum blockchain-envisioned security framework for IoT are provided.
