Geneva, Switzerland, June 26, 2025 -- SEALSQ Corp ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced expanded capabilities to support the rapidly evolving Internet of Medical Things (IoMT) landscape. SEALSQ’s technologies provide essential security components for applications that secure communications, authenticate devices, and enforce compliance with next-generation digital health frameworks.

The IoMT represents a vast network of interconnected medical devices, sensors, software, and healthcare systems utilizing internet connectivity to exchange information. By leveraging technologies like wireless communication, cloud computing, and now edge AI, IoMT offloads tasks and stores data on remote or local edge servers, vastly enhancing device functionality, storage capacity, and computational power. This integration is transforming healthcare delivery, fitness monitoring, and chronic disease management, addressing the challenges posed by rising global healthcare costs and aging populations.

As IoMT continues to expand, the need for enhanced cybersecurity becomes critical.

Most communications between devices and cloud servers occur over public networks, posing significant risks of unauthorized access. Malicious actors can exploit vulnerabilities to gain access to sensitive data, manipulate medical outcomes, or impersonate trusted systems. Ensuring the authenticity and integrity of transmitted data is essential to preventing attacks such as replay, man-in-the-middle, and denial-of-service incidents.

SEALSQ supports IoMT evolving needs by delivering security components that protect physical access to facilities, secure communications, and authenticate devices across government and consumer healthcare settings.

While its Smart Card reader chips are integrated into IDENTIV terminals used by major European healthcare systems to read patient cards securely, SEALSQ’s Public Key Infrastructure (PKI) and Secure Elements also enable in the field authentication and encryption for remote patient monitoring systems, protecting the flow of medical data between wearable devices and hospital systems.

Building on these foundations, SEALSQ has expanded its capabilities to support edge-based cryptographic authentication, enabling AI-powered medical devices to securely process data locally before transmitting only necessary insights into the cloud. This reduces latency and limits exposure to potential cyberattacks, aligning with modern edge AI deployments in IoMT.

Looking ahead to the evolution of digital threats, especially the advent of quantum computing, SEALSQ provides a unique value proposition by integrating PKI with Quantum-Resistant Cryptography and Post-Quantum Secure Hardware. Traditional algorithms such as RSA and ECC are increasingly vulnerable to quantum attacks. SEALSQ’s implementation of NIST-recommended algorithms like CRYSTALS-Kyber and Dilithium ensure robust protection against both classical and quantum adversaries. The Company’s secure hardware is now equipped with embedded post-quantum key management features, offering a tamper-resistant root of trust ideal for long-lifecycle medical devices.

“Security is a critical component of IoMT, given the sensitive nature of healthcare data and the potential risks associated with breaches,” stated Bernard Vian, SEALSQ’s Managing Director. “SEALSQ’s post-quantum technology offers a robust and scalable solution to safeguard IoMT networks from emerging cyber threats, while enabling compliant and efficient healthcare service delivery.”

As the digital transformation of healthcare accelerates, SEALSQ remains committed to empowering medical ecosystems with trusted, interoperable, and quantum-resilient technologies built to secure the future of connected care.
