UK based eSIM and iSIM specialist Kigen has achieved GSMA eUICC Security Assurance (eSA) certification for its new automotive eSIMs, making them the industry’s first eSA-certified eSIM that support SGP.32 v1.3, GSMA’s latest IoT eSIM (eUICC) specification, the company says.
The certification combines Kigen’s eSIM OS with Infineon’s Tegrion SLI22 automotive security controller, giving connected-vehicle OEMs and Tier 1s a secure, standards-current platform built for fleets.
As cars and two-wheeled vehicles become increasingly software-defined and connected, Kigen’s automotive eSIM has been certified across the Tegrion SLx22 chip family. The portfolio includes the Automotive SLI22, Consumer SLC22, which supports SGP.22 v2.7, and Industrial IoT SLM22, supporting SGP.32 v1.3.
All three products share the same operating system, hardware platform, development tools and management stack. According to Kigen, this enables automotive manufacturers to use a common security platform across infotainment, telematics and headless vehicle systems, reducing platform fragmentation and development time while supporting deployment across connected vehicles and industrial fleets.
Kigen’s implementation supports enhancements introduced in SGP.32 v1.3, published in May 2026, including direct and indirect profile downloads, digital activation codes and emergency profile handling for connected vehicles. According to Kigen, early support for the latest eSIM standards can help OEMs and operators reduce the risk of their architectures becoming outdated, enabling systems qualified today to remain relevant throughout longer vehicle development programs.
Post-quantum cryptography (PQC) is increasingly important for connected vehicles, where long service lives make hardware replacement impractical. Although PQC is not yet part of the GSMA specifications, Kigen can support OEMs in implementing hybrid key encapsulation that combines classical and quantum-safe algorithms on the same platform. OEMs can test end-to-end PQC-resistant communications using Kigen’s C-SDK development suite and test eSIM samples to prepare for long-term security against emerging quantum threats.
“Vehicles are becoming long-lived software platforms, so their connectivity trust anchor must remain secure and manageable long after production,” said Vincent Korstanje, CEO, Kigen.
“Kigen’s new eSA-certified automotive eSIMs give car manufacturers a secure path from factory provisioning to global fleet operation while preserving freedom to evolve connectivity throughout the vehicle lifetime.
“Given the market maturity of our eIM, the time to achieve this certification demonstrates the deep collaboration of Kigen’s product, engineering, certification and operations teams with technology and ecosystem partners.”
“Kigen has played a leading role in shaping the evolution of eSIM for IoT, including through Dr Saïd Gharout‘s leadership of the GSMA eSIM Technical Working Group,” added Gloria Trujillo, eSIM technical director, GSMA. “This latest achievement, with the industry’s first eSA-certified eSIMs supporting SGP.32 v1.3, is an important step in translating that standards leadership into secure, interoperable technology for the next generation of connected IoT and vehicle fleets.”
Katherine Diao, head of IoT and automotive industry at China Mobile International, said, “China Mobile International is pleased to partner with Kigen to introduce SGP.32-based security solutions to Chinese automakers, supporting global deployment, CRA-aligned processes, and reliable connectivity for vehicles designed for long service life.”
