How Hybrid DLT is Revolutionising IoT Connectivity and Quantum Security
The Internet of Things (IoT) isn’t just a tech buzzword—it’s the driving force behind innovations in healthcare, smart cities, and beyond. But as IoT networks expand, traditional centralized models struggle to keep up. The solution? Hybrid Distributed Ledger Technology (DLT). Let’s dive into how hybrid DLT is transforming modern connectivity and addressing the imminent challenges posed by quantum computing.
What is IoT and Why is it Crucial Today?
IoT represents a web of interconnected physical devices embedded with sensors and software that exchange data. From wearable health monitors to smart city infrastructure, IoT plays a pivotal role in various sectors:
- Healthcare: Wearables track patient health in real-time, improving outcomes and reducing hospital visits.
- Smart Cities: IoT optimises everything from energy usage to traffic management, making urban areas more efficient and liveable.
In essence, IoT is the backbone of our increasingly connected world, enabling real-time data sharing and decision-making across diverse applications.
The Challenges with Traditional Centralized Infrastructure
Traditional centralized systems aggregate data to a single server or cloud, which can lead to several issues:
-
Security Vulnerabilities: Centralized systems are prime targets for cyberattacks. The 2016 Mirai botnet attack is a stark example of how vulnerable these systems can be.
-
Scalability Issues: Central servers struggle to handle the vast amounts of data from billions of IoT devices, leading to performance bottlenecks and inefficiencies.
-
Privacy Concerns: Centralised systems often require users to relinquish control over their data to third parties, raising significant privacy issues.
Hybrid DLT addresses these challenges by decentralising data management, thus enhancing security, scalability, and privacy.
The Role of Hybrid DLT in Modern Connectivity
Hybrid Distributed Ledger Technology (DLT) is pivotal in transforming IoT networks. Here’s how it enhances connectivity:
Enhanced Security
-
Decentralisation: By spreading data across multiple nodes, hybrid DLT eliminates single points of failure. This makes it much harder for attackers to compromise the system.
-
Real-World Example: Platforms like Filament use blockchain-based IoT security to secure machine-to-machine (M2M) communications, ensuring only authorised devices interact.
Improved Scalability
-
Distributed Workload: Hybrid DLT distributes data processing across a network, accommodating the growing volume of IoT data without degradation in performance.
-
Smart Cities: In smart cities, hybrid DLT enables efficient management of real-time data, from traffic flow to utility services.
Strengthened Privacy
-
User Control: Decentralised networks allow for encrypted data storage across nodes, ensuring only authorised parties have access.
-
Example: IOTA, a platform using a distributed ledger, ensures secure and private data sharing between devices, aligning with privacy-by-design principles.
Why Quantum Security Matters Now
Quantum computing is nearing reality, and it threatens traditional cryptographic systems. Unlike classical computers, quantum computers use qubits, which can process complex calculations at unprecedented speeds. This poses a risk to current encryption methods used in IoT networks.
Quantum computers could potentially break existing cryptographic protections, exposing IoT data to manipulation and theft. The implications for sectors like healthcare, finance, and national security are severe.

Quantum-Resistant Algorithms
- SPHINCS+: This post-quantum algorithm, approved by NIST, offers strong security against quantum threats, securing the blockchain from future advancements in quantum computing.
The Urgency of Transitioning to Quantum-Secure Infrastructure
The U.S. National Institute of Standards and Technology (NIST) is spearheading efforts to standardise post-quantum cryptography (PQC) to prepare for quantum threats. As quantum computing evolves, transitioning to quantum-safe cryptography is no longer optional but essential.
“Harvest now, decrypt later” illustrates the need for immediate action—data secured today might be vulnerable to future quantum decryption.
