SEALSQ and Inventec Appliances Showcase Thermostat IoT Devices with Matter Security at Computex

GENEVA – May 23, 2023: WISeKey International Holding Ltd. (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, AI, Blockchain, and semiconductors company, today announced that its wholly-owned subsidiary SEALSQ Corp. (NASDAQ: LAES) and Inventec Appliances (Jiangning) Corporation (“Inventec Appliances”), a leader in smart terminal and IoT device solutions, will demonstrate a Thermostat IoT turnkey platform with Device Attestation Certificate for Matter.

“SEALSQ’s INeS platform enables Inventec Appliances to offer features like faster connection to a Matter ecosystem for the devices they manufacture. Additionally, it provides higher flexibility for OEMs to manage certificates at design and manufacturing stages,” said David Khalifa, VP of Global Sales for WISeKey.

“Inventec Appliances is pleased to cooperate with SEALSQ in taking IoT devices to the next level,” said Yong-Cai Bian, Vice President at Inventec Appliances. “The combination of Inventec Appliances’ Thermostat and SEALSQ’s PKI services provides OEM’s with ready-to-use Matter-trusted products.”

The growing adoption of Matter standard for the smart home industry will greatly improve interoperability between devices and security-by-design in the smart home industry, creating a more efficient and safer experience for consumers. This is in full alignment with SEALSQ’s mission to contribute in building a safer connected world, as described on SEALSQ Device Attestation for Matter.

Matter participants may gain the following benefits by partnering with SEALSQ:

  • Reducing time-to-market in achieving Matter compliance.
  • Reducing costs of technology, maintenance, staffing and ongoing compliance.
  • Enjoying more flexible deployment options, including on-premises, hosted or batch issuance.
  • Simplifying management of device attestation certificates and product attestation intermediates through SEALSQ INeS CMS Platform for IoT.
  • Gaining efficiency using a scalable platform to sign and secure device updates.

Matter, an industry-led effort of the CSA, brings together the world’s leading manufacturers and service providers to achieve secure, reliable and seamless use of smart home devices. Matter enables IP-based networking and communication across smart home devices, mobile applications and smart home ecosystems. Matter devices offer consumers assurances of secure use through a consortium-led standard for authenticating device identity that only allows Matter-certified devices to connect to the network. Device attestation process allows existing Matter devices to locally confirm new ones when recognized by the local network, and quickly remove non-compliant devices when needed.

The platform is on display at Computex with SEALSQ’s booth (Taipei Nangang Exhibition Center, Hall 2, InnoVEX Q0716).

SEALSQ is a wholly owned subsidiary of the WISeKey Group that focuses on developing and selling Semiconductors, PKI and Post-Quantum technology hardware and software products. Our Post-Quantum solutions include Post-Quantum microchips and devices that can be used in a variety of applications, from Multi-Factor Authentication devices, Home Automation, 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 Elliptic Curve Cryptography (ECC). PQC aims to develop new cryptographic methods that are secure against quantum attacks. For more information, visit
