Securing the future internet of things with post‐quantum cryptography

Adarsh Kumar, Carlo Ottaviani, Sukhpal Singh Gill +1 more

Abstract Traditional and lightweight cryptography primitives and protocols are insecure against quantum attacks. Thus, a real‐time application using traditional or lightweight cryptography primitives and protocols does not ensure full‐proof security. Post‐quantum cryptography is important for the internet of things (IoT) due to its security against quantum attacks. This paper offers a broad literature analysis of post‐quantum cryptography for IoT networks, including the challenges and research directions to adopt in real‐time applications. The work draws focus towards post‐quantum cryptosystems that are useful for resource‐constraint devices. Further, those quantum attacks are surveyed, which may occur over traditional and lightweight cryptographic primitives.

PQ-FLAT: A New Quantum-Resistant And Lightweight Authentication Approach for M2M Devices

Engin Karacan, Sedat Akleylek, Aykut Karakaya

It is believed that traditional asymmetric cryptosystems are compromised and symmetric cryptography can be used in the post-quantum world. In this paper, a new model based on post-quantum a set of FLAT (PQ-FLAT) protocol is proposed to ensure security in the machine to machine communication with post-quantum cryptography and it is inspired by the federated lightweight authentication of things (FLAT) protocol, which works effectively for resource-constrained devices in machine to machine (M2M) communication systems. The proposed model includes resource-constrained devices, certificate provider (CP), and service provider (SP). Communication of the certificate provider between resource-constrained devices is encrypted with AES. Instead of the asymmetric cryptography system between the certificate provider and the service provider, a lattice-based encryption mechanism, secure in the post-quantum world, is used. Thus, the FLAT protocol for resource-constrained devices is made resistant to post-quantum changes.

Quantum-Resistant Blockchain Authentication Protocol: Securing Decentralized Systems Against Post-Quantum Attacks

Dhruv Dhayal, Preeti Preeti, Pankaj Kumar Varshney +1 more

The fast growth of quantum computing makes the old modes of cryptography, be it RSA or ECC, weak to quantum attacks, especially when it employs Shor's algorithm. Threatening also builds up on the post-quantum age regarding blockchain technology and its external cryptography, which secures reliable transactions and authentication. This study will address the importance of quantum resistant blockchain authentication protocols for the security of decentralized systems against any forward-looking quantum-enabled attacks. This paper goes through different classifications of post-quantum cryptography like lattice-based, hash-based, multivariate polynomial, and code-based cryptography, taking an effort to analyze their compatibility with blockchain use cases.[8] Moreover, we also introduce the innovative quantum-resistant authentication model designed to enhance security while not compromising upon efficiency.[2] [3] Our proposed model would ensure scalability and less computational overhead by partially providing immunity to quantum adversaries through its underlying use of post-quantum signature schemes and lightweight key exchange mechanisms. This research aims at laying the foundation for developing a secure blockchain ecosystem against quantum threats, heading toward a resistant future-proof decentralized infrastructure. [4] [5]
