Tecell’s platform secures communication between chargers and the CMS using industry-standard TLS 1.3 encryption, ensuring all data transmitted is protected from interception or tampering. The system automatically manages certificate lifecycle, including issuance, renewal, and rotation, to maintain continuous security. All connections are validated through mutual authentication, where both the charger and CMS verify each other’s identity before exchanging data. This approach prevents unauthorized access and ensures compliance with EV charging security standards.
How TLS Works in Practice
In real-world deployments, Tecell’s TLS implementation operates seamlessly in the background. When a charger connects to the CMS, it initiates a TLS handshake that negotiates encryption parameters and verifies the CMS’s identity using a trusted certificate authority. The charger then confirms the CMS’s identity through a digital certificate, ensuring no man-in-the-middle attacks can occur. This process happens in milliseconds, with no impact on charging speed or user experience.
Why This Matters for Charge Point Operators
For charge point operators, secure TLS communication is essential for protecting sensitive data like user credentials, payment information, and charging session logs. Without proper encryption, this data could be exposed to attackers, leading to compliance violations and potential liability. Tecell’s approach ensures operators meet regulatory requirements while maintaining trust with their users. The platform also supports audit trails that track all TLS connections, helping operators monitor and troubleshoot security events.
