The expansion of connected devices is anticipated to fuel the growth of the post-quantum cryptography (PQC) for the Internet of Things (IoT) market going forward. "Connected devices" refers to internet-enabled physical objects that communicate and exchange data across networks. The expansion of connected devices is largely driven by the accelerating digitalization across various industries, as sectors such as healthcare, manufacturing, and smart infrastructure are deploying internet-connected devices at scale to enable automation and real-time data exchange, thereby significantly enlarging the IoT ecosystem. The increasing proliferation of connected devices generates a pressing need for quantum-resistant encryption, as each added device constitutes a potential vulnerability that conventional cryptography may not safeguard against future quantum computing attacks. For example, in February 2025, according to Scania, a Sweden-based commercial vehicle manufacturer, by the end of 2024, Scania had approximately 638,000 connected vehicles, a number that continues to grow rapidly. Thus, the expansion of connected devices is driving the growth of the post-quantum cryptography for the Internet of Things (IoT) market.

Leading companies operating in the post-quantum crypto for the internet of things (IoT) market are focusing on technology advancements such as post-quantum-resistant public key infrastructure (PKI) solutions to secure IoT devices against future quantum computing threats while ensuring scalability and compatibility with resource-constrained environments. Post-quantum-resistant PKI refers to cryptographic infrastructures that integrate NIST-aligned post-quantum algorithms for device authentication, secure key exchange, lifecycle management, and long-term data protection in IoT ecosystems.
