Swiss firm Sealsq is improving IoT security with scalable PKI-based digital identity and integrity offerings.

The company focuses on developing and selling semiconductors, PKI and post-quantum hardware and software. The latest offering embeds PKI-based digital identity and integrity into every connected device at scale.

From the initial stages of design and manufacturing to the product’s entire lifecycle in the field, it ensures seamless security for the growing IoT ecosystem. Leveraging PKI, a time-tested and standard technology, Sealsq provides security and scalability, specifically designed to protect IoT devices.

As the number of connected devices continues to surge, security has emerged as a critical problem. Sealsq addresses this by offering a suite of products and services that simplify the adoption of PKI-based digital identity. From certificate generation and injection to lifecycle management, the PKI services enable organisations to integrate robust security without friction.

“At the core of Sealsq’s value proposition is not only the design and production of secure microcontrollers but also the ability to securely and conveniently generate, inject and manage a unique and universally trusted digital identity for every connected device,” said Bernard Vian, managing director of Sealsq. “This capability ensures that each device has a distinct and verifiable identity, protecting its integrity from manufacturing through its entire lifecycle.”

Sealsq secures devices from the design phase, ensuring data integrity and authenticity throughout the entire lifecycle. Designed to meet the demands of modern IoT environments, it can scale effortlessly to accommodate millions of devices.

With PKI’s track record in safeguarding data and communications, Sealsq offers assurance for device identity, authentication and data integrity. It provides a complete set of tools and services, including certificate issuance, management and integration with existing security infrastructure, making it easier for businesses to adopt and manage IoT security.

As businesses across industries such as manufacturing, healthcare, automotive and smart cities continue to adopt connected devices, the need for secure identity management is becoming increasingly vital. This PKI-based approach (www.sealsq.com/pki-provisioning-for-iot) guarantees that each IoT device is secure, authenticated and trusted throughout its lifecycle.

Sealsq’s (www.sealsq.com) products can be used in applications, from multi-factor authentication tokens, smart energy, smart home appliances, medical and healthcare and IT network infrastructure, to automotive, industrial automation and control systems.

Post-quantum cryptography (PQC) refers to cryptographic methods that are secure against an attack by a quantum computer. As quantum computers become more powerful, they may be able to break many of the cryptographic methods that are currently used to protect sensitive information, such as RSA and ECC. PQC aims to develop cryptographic methods that are secure against quantum attacks.
