Wi-SUN Alliance Selects WISeKey PKI Services to Deliver Digital Certificates to Consortium Members

Geneva – May 23, 2022 – WISeKey International Holding (“WISeKey”, SIX: WIHN, NASDAQ: WKEY), a leading security Certificate Authority and provider of identity solutions, today announced that it has been appointed by the Wi-SUN Alliance to provide global PKI-based security services for Wi-SUN members, especially around the deployment of its Certificate Management Solution (CMS), INeSTM, dedicated to the Internet of Things (IoT).

This partnership will foster WISeKey’s business opportunities with more than 300 members in 46 countries, within an ecosystem including device vendors, silicon vendors, utilities, cities with more than 100 million endpoints.

Wi-SUN FAN supports applications that enhance efficiency, quality of service and resilience including smart utilities, smart cities, smart grids. Wi-SUN FAN protocol supports X509 digital certificates for device authentication. Digital security certificates are a cornerstone of IoT security. By offering a means for servers to verify the authenticity of the source of every incoming communication, they build trust.

Public key cryptography and digital certificates are used to implement strong authentication, data encryption and digital signatures. The INeSTM CMS for IoT is a flexible and scalable certificate management platform, used to issue, validate and manage the digital identities of objects in a PKI solution, represented as Digital Certificates, according to the X509 ITU (ISO/IEC 9594-8:2001) standards.

INeSTM integrates a Device Management capability and can be used through a web interface and REST API, which enables customers and developers to automate the device and certificate management, integrating it with the manufacturing chain.

“We are excited that WISeKey’s will provide its expertise to manage the implementation of Wi-SUN PKI security for our members,” said Phil Beecher, President and CE0, Wi-SUN Alliance. “WISeKey is an expert at designing, governing and managing large PKI ecosystems to ensure device identity supporting millions of connected devices. The WISeKey team continues to work closely with us to shape the efficient roll out of the Wi-SUN FAN Networks.”

“A strong and protected (IoT) device identity, is a foundation building block for secure IoT solutions,” commented Gweltas Radenac, Director of WISeKey IoT Business Line. “Our Security solutions allow Wi-SUN members and partners to effectively implement and leverage hardware-anchored digital device identities at scale.”

WISeKey’s secure semiconductors are certified for Evaluation Assurance Level + (EAL4+) according to the international standard Common Criteria for Information Technology Security Evaluation (CC).
