Kigen Automotive eSIMs Gain eSA Certification for SGP.32

Kigen Automotive eSIMs Achieve GSMA eSA Certification

On September 23, Kigen announced that its new Kigen Automotive eSIMs have achieved GSMA eUICC Security Assurance (eSA) certification. The company describes the products as the industry's first eSA-certified eSIMs supporting SGP.32 v1.3, the latest GSMA IoT eSIM (eUICC) specification. The certification establishes a standards-current security foundation for connected-vehicle applications and is aimed at automotive OEMs and Tier-1 suppliers. Kigen Automotive eSIMs are scheduled to become available for OEM sampling in an ETSI MFF2 package from October 2026, giving manufacturers access to the certified platform as they evaluate eSIM technology for connected-vehicle programs.

Security Architecture Combines Kigen and Infineon Technology

The certification combines Kigen's eSIM operating system with Infineon Technologies' TEGRION SLI22 automotive security controller. This combination provides connected-vehicle OEMs and Tier-1 suppliers with a secure platform designed around current standards and long vehicle service lifecycles. The architecture is intended for fleets that must remain secure for a decade or longer, making long-term security assurance a central consideration. By combining the eSIM OS with an automotive security controller, the certified solution brings together the components required for secure connectivity and hardware-based protection within an automotive eSIM platform.

GSMA Assurance Covers Manufacturing and Subscription Management

Kigen said its full eSIM stack assurance extends across GSMA SAS-UP certification for manufacturing and GSMA SAS-SM certification for subscription management. These certifications complement the eSA certification of the automotive eSIM platform by addressing security assurance across different parts of the eSIM lifecycle. For OEMs and Tier-1 suppliers, the combined assurance approach is relevant to connected-vehicle deployments in which secure manufacturing, subscription management, and device-level security must operate together. The stated objective is to provide a platform that can support long-lived automotive connectivity while remaining aligned with applicable GSMA security and eSIM specifications.

Quantum-Safe and Classical Security Support

Kigen also said it can support OEMs that have implemented hybrid key encapsulation combining classical and quantum-safe algorithms on the same platform. This approach allows both algorithm types to be implemented together rather than requiring separate platforms for conventional and quantum-safe cryptographic methods. The capability is relevant to automotive programs where connected vehicles may remain in service for more than a decade and therefore require consideration of long-term security requirements. Kigen's stated support for hybrid key encapsulation adds another security option for OEMs developing connected-vehicle architectures around certified eSIM technology and evolving cryptographic requirements.

OEM Sampling Timeline and Package

The newly certified Automotive eSIMs will be available for OEM sampling from October 2026 in the ETSI MFF2 package. The sampling timeline provides automotive manufacturers and Tier-1 suppliers with an opportunity to evaluate the certified eSIM implementation ahead of broader deployment decisions. The October 2026 availability follows the September 23 certification announcement and specifically identifies the MFF2 package as the sampling format. The combination of GSMA eSA certification, SGP.32 v1.3 support, the TEGRION SLI22 security controller, and the wider GSMA assurance certifications defines the technical foundation Kigen is presenting for future connected-vehicle programs.

Certification and Availability Details

The announcement identifies several technical and commercial milestones associated with the new automotive eSIM platform. The certification covers eSA requirements while the implementation supports SGP.32 v1.3, and OEM sampling is planned for October 2026. The platform also combines Kigen's eSIM OS with Infineon's TEGRION SLI22 automotive security controller and is supported by Kigen's broader GSMA SAS-UP and SAS-SM certifications. Together, these details describe the security architecture, standards alignment, manufacturing and subscription-management assurance, and initial availability that OEMs and Tier-1 suppliers can consider when evaluating the technology.

Industry Impact & Outlook

The certification gives connected-vehicle OEMs and Tier-1 suppliers a standards-current eSIM platform that combines security assurance with support for the latest SGP.32 v1.3 specification identified in the announcement. Its significance is particularly relevant to automotive programs designed around long vehicle lifecycles, where connectivity security must remain dependable over many years. The October 2026 OEM sampling milestone could allow manufacturers to assess the platform within upcoming connected-vehicle architectures, while the combination of classical and quantum-safe algorithms provides an additional security consideration for longer-term deployments. The practical impact will depend on how OEMs and suppliers incorporate the certified technology into their individual vehicle and connectivity programs.
