Revolutionizing EV Charger Security with Lynx’s Advanced Platform Hardening
When an EV charger manufacturer needed to secure public charging stations against rising cyber threats, Lynx delivered. Through cutting-edge encryption, secure bootloaders, and platform hardening, Lynx built a scalable, future-proof system that enabled the client to enter the market with confidence.

Protecting Public Charging Infrastructure with Next-Generation Security
An EV charger manufacturer partnered with Lynx to address critical security challenges. Faced with safeguarding sensitive customer data and preventing unauthorized access to their devices, the client required a solution that ensured compliance and operational integrity. Lynx provided an end-to-end security framework, integrating encryption, key management, and platform hardening. The result? A secure, scalable platform ready to meet the demands of the competitive EV market.
About the Client: Leading Innovation in the EV Market
The client is a cutting-edge manufacturer focused on public EV charging infrastructure. They sought to not only protect sensitive customer data but also differentiate their offerings with robust security as a cornerstone of their brand. By leveraging Lynx’s expertise, the client was able to gain a competitive edge while meeting stringent security and compliance standards.
Challenge
Securing Public Infrastructure Without Sacrificing Usability
The client faced critical challenges: ensuring only authenticated software could run on devices, protecting sensitive user data, and maintaining a secure update mechanism. Complicating these goals was the need to harden the platform while ensuring compatibility with existing systems and preserving usability. Without these measures, the platform would be vulnerable to data breaches, cyberattacks, and reputational damage.
Key Challenges:
- Preventing unauthorized software execution.
- Implementing robust encryption for sensitive data.
- Ensuring secure over-the-air (OTA) updates.
- Hardening the platform against tampering or misuse.
Solution
A Holistic Approach to EV Charger Security
Lynx implemented a comprehensive security solution tailored to the client’s needs. By leveraging advanced technologies and close collaboration with the client’s team, Lynx ensured the platform was secure, compliant, and market-ready. Key components included:
- Secure Bootloader Implementation: Public/private key authentication was used to verify the bootloader, ensuring only trusted software could execute.
- Full Disk Encryption: Sensitive data, including the root filesystem and application data, was protected with dm-crypt encryption.
- Processor-Specific Enhancements: Leveraging TrustZone and OP-TEE technologies enabled confidential data storage optimized for the client’s processor architecture.
- Platform Hardening: Lynx disabled weak protocols and unnecessary ports, implemented meta-security measures, and ensured the system was resistant to tampering.
- Secure OTA Updates: Added encryption and server authentication to the client’s existing update mechanism, enabling safe and reliable software updates.
Results
A Secure Platform Ready to Seize the EV Market
The client successfully launched their secure EV charging platform, setting a new standard for public infrastructure security. Lynx’s solution not only ensured compliance with stringent industry standards but also reduced the risk of breaches and operational failures.
Key Outcomes:
- 100% data encryption for customer data and application files.
- Fully secure OTA update mechanism with encryption and authentication.
- Platform hardening to minimize attack surfaces and prevent tampering.
- On-time delivery through collaboration with TI.
- Positioned the client for success in the competitive EV market.
