Quantum-safe authentication mechanism for IoT devices using hash-based post-quantum signature schemes: a short review

Purvi Tandel, Jitendra Nasriwala

We are surrounded by many smart applications that make human life efficient. The general concept of IoT applications involves communication between devices. To make our smart environment secure, authentication is the most important requirement to be achieved to avoid unwanted attacks. Cryptographic schemes used currently in such IoT devices are public-key cryptographic primitives that are vulnerable to future quantum attacks. Quantum approaches derived by Shor and Grover will break the public-key primitives with square root and cube root speedups. Hence, there is a need to develop a successful and efficient signature scheme to authenticate such devices. Post-quantum cryptographic approaches are based on hard mathematical problems which are difficult to break by future attacks. Amongst all these post-quantum signature approaches, hash-based post-quantum signatures incorporate existing hash algorithms to achieve the required security level. This paper summarises stateful hash-based post-quantum signature schemes that can be implemented on constrained devices for IoT applications.

Blockchain-Based Key State Management for IoT Devices in Post-Quantum Era

Vincent Lew Kok Seng, Au Thien Wan, S. H. Shah Newaz +1 more

Blockchain has been paving the way for new business opportunities as we have witnessed over the last few years. It will continue to proliferate further and be adopted in increasingly diverse sectors. One area of research in Blockchain is how it can be used in Internet of Things (IoT) based applications like Unmanned Aerial Vehicles (UAV), Smart cities and Healthcare. However, with the advent of quantum technology, some widely used security algorithms in blockchain are vulnerable (i.e., quantum algorithms can exponentially solve cryptographic algorithms used to digitally sign or encrypt data), thereby diminishing communication security. Thus, post-quantum algorithms are at the forefront of research to secure data before quantum technologies can fully mature. Early standardized post-quantum algorithms such as hash-based one-time signatures, relies on the proven one-way-ness of hashing algorithm. Hash-based one-time signatures require robust secret key management systems to prevent security degradation. To safeguard IoT applications from quantum threats, this paper proposes a solution which utilizes both hash-based one-time signatures and blockchain to cover each technology's weaknesses.
