Case Study: a leading Tier-1 supplier secures ECU communication with Diconium

Leading Tier-1 Supplier Company - Customer Case Study

A leading tier-1 automotive supplier company faced the challenge of securing UART communication for its next-generation ECUs against spoofing and replay attacks. After their original security vendor withdrew support, they required a solution for secure credential storage and cryptographic processing that could validate OEM-approved hardware without relying on a Hardware Security Module. They partnered with Diconium to address this critical automotive cybersecurity need.

Diconium developed a custom Trusted Application built on the Kinibi Trusted Execution Environment (TEE). Their solution implemented a secure three-step handshake protocol that used pre-shared keys to establish a protected session, ensuring only authorized hardware could issue commands. The Diconium solution successfully defended against attacks during pentesting, allowing the customer to launch their secure product and meet stringent automotive compliance standards.
